Do not use a pressure washer at any setting; high-pressure spray permanently compresses the pleat fibers and reduces effective filter area in a way that cannot be undone.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eDeep Soak Cleaning and Element Replacement\u003c\/h3\u003e\n\n  \u003cp\u003e\n    Surface rinsing clears the bulk debris load but does not remove oils, mineral scale, and fine organic compounds that work into the pleat material over a season. Soaking all four elements overnight in a dedicated pool cartridge cleaning solution at the start of each swim season, and again during periods of heavy use, is the most reliable way to restore operating pressure to the recorded clean baseline and extend element service life.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    Replace a CX580XRE element when pressure does not return to the clean baseline after a full clean-and-soak cycle, when the pleats show visible tears or permanent compression, or when end cap cracking allows unfiltered water to bypass the media. Because the W3C3030 allows individual element replacement, inspect each element's condition at every cleaning rather than waiting for a full set to fail.\n  \u003c\/p\u003e\n\n  \u003ch3\u003ePump Pairing and Flow\u003c\/h3\u003e\n\n  \u003cp\u003e\n    The W3C3030's 122 GPM design flow rate fits the output of most standard residential pump configurations for in-ground pools. For variable-speed pump installations, lower speeds during overnight filtration reduce electrical costs while keeping the filter operating at pressures that extend element life. If your pool also has a spa or water features that draw higher combined flow at full speed, verify the total system GPM at each operating mode stays within the filter's rated ceiling. If high-speed combined demand consistently approaches or exceeds 122 GPM, the \u003ca href=\"https:\/\/nonstopswim.com\/products\/hayward-swimclear-425-sq-ft-4-element-cartridge-pool-filter\"\u003eW3C4030 at 150 GPM\u003c\/a\u003e provides additional headroom.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\n  \u003cp\u003e\n    The W3C3030 connects via CPVC 2\" or 2.5\" union couplings at the inlet and outlet. No multiport valve is needed. Connect pump discharge to the filter inlet and filter outlet to the pool return. The tank requires 50.5\" of vertical overhead clearance for cartridge removal during service; confirm this at the equipment pad before installation. Install all four CX580XRE cartridges before closing the lid. Prime by running the pump with the air relief valve open until a steady stream of water (not air) flows from the port, then close the valve. Record the gauge reading as the clean baseline: a rise of 8 to 10 PSI above this number indicates cleaning is due.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eWinterizing the W3C3030\u003c\/h3\u003e\n\n  \u003cp\u003e\n    At season end, remove all four CX580XRE cartridges, perform a full cleaning and soak cycle on each element, and inspect each carefully before storage. Store cartridges indoors in a dry location away from sunlight and freezing temperatures. Use the 1.5\" integral drain to fully empty the tank body, leave the lid open to allow residual moisture to evaporate, and store the tank in a protected location.

Soaking all four elements overnight in a dedicated pool cartridge cleaning solution at the start of each swim season, and again during periods of heavy use, is the most reliable way to restore operating pressure to the recorded clean baseline and extend element service life.\u003c\/p\u003e\n\u003cp\u003eReplace a CX880XRE element when pressure does not return to the clean baseline after a full clean-and-soak cycle, when the pleats show visible tears or permanent compression, or when end cap cracking allows unfiltered water to bypass the media. Because the W3C4030 allows individual element replacement, inspect each element's condition at every cleaning rather than waiting for a full set to fail.\u003c\/p\u003e\n\u003ch3\u003ePump Pairing and Flow\u003c\/h3\u003e\n\u003cp\u003eThe W3C4030's 150 GPM design flow rate accommodates a wide range of residential pump configurations. For installations with variable-speed pumps, lower speeds during overnight filtration cycles reduce electrical costs while keeping the filter working at pressures that extend element life. Higher-speed runs for spa jets or water features sit comfortably within the filter's rated flow. Confirm at commissioning that the pump's output at each operating speed is appropriate for the filter and that the system does not consistently run near the rated maximum, which accelerates pleat wear.\u003c\/p\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe W3C4030 connects via CPVC 2\" or 2.5\" union couplings at the inlet and outlet. No multiport valve is needed. Connect pump discharge to the filter inlet and filter outlet to the pool return. The tank requires 58.5\" of vertical overhead clearance for cartridge removal during service; confirm this at the equipment pad before installation. Install all four CX880XRE cartridges before closing the lid. Prime by running the pump with the air relief valve open until a steady stream of water (not air) flows from the port, then close the valve. Record the gauge reading as the clean baseline: a rise of 8 to 10 PSI above this number indicates cleaning is due.\u003c\/p\u003e\n\u003ch3\u003eWinterizing the W3C4030\u003c\/h3\u003e\n\u003cp\u003eAt season end, remove all four CX880XRE cartridges, perform a full cleaning and soak cycle on each element, and inspect each carefully before storage. Store cartridges indoors in a dry location away from sunlight and freezing temperatures. Use the 1.5\" integral drain to fully empty the tank body, leave the lid open to allow residual moisture to evaporate, and store the tank in a protected location. In hard-freeze climates, bring the tank indoors or into an insulated space to prevent ice damage to the tank body and seals.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat replacement cartridge does the W3C4030 use, and how many are required?\u003c\/summary\u003e\n\u003cp\u003eThe W3C4030 uses four Hayward CX880XRE replacement cartridge elements, one per position in the Quad-Cluster manifold. Each element is 106 sq ft (7\" outer diameter, 25.5\" length). A full replacement set requires four CX880XRE units. Common aftermarket cross-references include Unicel C-7488 and Pleatco PA106.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the design flow rate for the W3C4030?\u003c\/summary\u003e\n\u003cp\u003eThe W3C4030 has a published design flow rate of 150 GPM per Hayward's documentation. Sustained operation consistently at or near the rated maximum accelerates element wear and shortens cleaning intervals, so the pump should be sized to meet the pool's daily turnover requirements rather than running at the ceiling continuously.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDoes the W3C4030 require a backwash valve or drain line?\u003c\/summary\u003e\n\u003cp\u003eNo. The W3C4030 uses CPVC union coupling connections at the inlet and outlet as its only plumbing connections. There is no multiport valve and no backwash drain line. Cleaning is done by removing the four cartridge elements and rinsing them by hand with a garden hose.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I use cartridges from the 325 or 525 sq ft SwimClear models in the W3C4030?\u003c\/summary\u003e\n\u003cp\u003eNo. The W3C4030 uses CX880XRE elements (106 sq ft each). The 325 sq ft model uses smaller CX580XRE elements and the 525 sq ft model uses larger CX1280XRE elements. Installing the wrong element results in improper manifold seating that allows unfiltered water to bypass the cartridge media. Always match replacement cartridges to the model number on the filter tank or in the owner's manual.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow does the W3C4030 differ from the 525 sq ft SwimClear model?\u003c\/summary\u003e\n\u003cp\u003eBoth models share the same 150 GPM design flow rate and four-element Quad-Cluster configuration. The 525 sq ft model provides an additional 100 sq ft of total filter area (131 sq ft per element vs. 106 sq ft per element) via larger CX1280XRE cartridges. The additional filter area extends the interval between required cleanings and provides more headroom for pools with consistently high debris loads, heavy bather traffic, or heated environments where filter demand is elevated year-round.

Once fully depressurized, open the one-piece clamp, lift the lid, and remove each CX1280XRE element individually. At 131 sq ft per element and 32.875\" in length, these are the largest cartridges in the SwimClear line; have a stable surface ready nearby and note which element came from which position so you can track wear differences across the Quad-Cluster over time.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    Rinse each element top to bottom with a garden hose and spray nozzle, working between every pleat fold on all sides. Continue until the runoff runs clear. Do not use a pressure washer at any setting; high-pressure spray permanently compresses the pleat fibers and cannot be undone.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eDeep Soak Cleaning and Element Replacement\u003c\/h3\u003e\n\n  \u003cp\u003e\n    Surface rinsing clears the bulk debris load but does not remove oils, mineral scale, and fine organic compounds that work into the pleat material over a season. Soaking all four elements overnight in a dedicated pool cartridge cleaning solution at the start of each swim season, and again midway through periods of heavy use, is the most reliable way to restore operating pressure to the recorded clean baseline and extend element service life.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    Replace a CX1280XRE element when pressure does not return to the clean baseline after a full clean-and-soak cycle, when the pleats show visible tears or permanent compression, or when end cap cracking allows unfiltered water to bypass the media. Because the W3C5030 allows individual element replacement, inspect each element's condition at every cleaning rather than waiting for a full set to fail. At this element size, indoor storage at season end makes a meaningful difference in protecting the pleat material and end cap seals from off-season UV and freeze damage.\n  \u003c\/p\u003e\n\n  \u003ch3\u003ePump Pairing and Flow\u003c\/h3\u003e\n\n  \u003cp\u003e\n    The W3C5030 shares the same 150 GPM design flow rate as the W3C4030, so the two filters suit similar pump configurations. The practical difference is filter area: 525 sq ft vs. 425 sq ft means the W3C5030 holds more debris before pressure rises to the cleaning threshold, extending the interval between service events under equivalent conditions. For installations where the pump output comfortably fits within 150 GPM and the driving consideration is minimizing cleaning frequency, the W3C5030 is the stronger choice. For variable-speed pump installations, lower speeds during overnight filtration cycles keep the filter operating at pressures that extend element life while reducing electrical costs.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\n  \u003cp\u003e\n    The W3C5030 connects via CPVC 2\" or 2.5\" union couplings at the inlet and outlet. No multiport valve is needed. Connect pump discharge to the filter inlet and filter outlet to the pool return. This tank requires 68.5\" of vertical overhead clearance for cartridge removal during service, which is 10\" more than the W3C4030; verify this at the equipment pad before committing to placement. Install all four CX1280XRE cartridges before closing the lid. Prime by running the pump with the air relief valve open until a steady stream of water (not air) flows from the port, then close the valve. Record the gauge reading as the clean baseline: a rise of 8 to 10 PSI above this number indicates cleaning is due.\n  \u003c\/p\u003e\n\n  \u003ch3\u003eWinterizing the W3C5030\u003c\/h3\u003e\n\n  \u003cp\u003e\n    At season end, remove all four CX1280XRE cartridges, perform a full cleaning and soak cycle on each element, and inspect each carefully before storage. At this element size, indoor storage in a dry location away from sunlight and freezing temperatures is particularly important for protecting the pleat material and end cap seals. Use the 1.5\" integral drain to fully empty the tank body, leave the lid open to allow residual moisture to evaporate, and store the tank in a protected location. In hard-freeze climates, bring the tank indoors or into an insulated space to prevent ice damage to the tank body and seals.\n  \u003c\/p\u003e\n\n  \u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat replacement cartridge does the W3C5030 use, and how many are required?\u003c\/summary\u003e\n    \u003cp\u003eThe W3C5030 uses four Hayward CX1280XRE replacement cartridge elements, one per position in the Quad-Cluster manifold.

The difference between the two models is filter area (525 sq ft vs. 425 sq ft), not flow capacity. Sustained operation consistently near the rated maximum accelerates element wear and shortens cleaning intervals, so the pump should be sized to meet the pool's daily turnover requirements rather than running at the ceiling continuously.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eDoes the W3C5030 require a backwash valve or drain line?\u003c\/summary\u003e\n    \u003cp\u003eNo. The W3C5030 uses CPVC union coupling connections at the inlet and outlet as its only plumbing connections.

The W3C4030 uses shorter CX880XRE elements and the W3C3030 uses CX580XRE elements. Installing the wrong element results in improper manifold seating that allows unfiltered water to bypass the cartridge media.

Filtration Works in the Hayward ProGrid W3DE4820\u003c\/h2\u003e\n\n  \u003cp\u003eDiatomaceous earth is a naturally occurring, mined material composed of fossilized diatom shells with an extremely porous silica structure. When pool-grade D.E. powder is added through the skimmer with the pump running, it coats the fabric-covered grid elements inside the tank. Pool water passing through this D.E. cake is filtered to 5 microns on the first pass.\u003c\/p\u003e\n\n  \u003cp\u003eAs the cake loads with debris, operating pressure rises. The filter is serviced by backwashing through a compatible valve, which clears the spent D.E., followed by a fresh 6 lb D.E. charge to recoat the grids. Pool-grade D.E. must be used; food-grade and pest-control D.E. products are not appropriate for pool filtration.\u003c\/p\u003e\n\n  \u003ch2\u003eHayward W3DE4820 ProGrid D.E.

Filter\u003c\/h2\u003e\n\n  \u003cp\u003eWhen operating pressure rises 8 to 10 PSI above the recorded clean baseline, the filter needs servicing. Backwash through a compatible valve until the sight glass or discharge runs clear, then add a fresh 6 lb D.E. charge through the skimmer with the pump running. Always pre-slurry the D.E. powder in a bucket of water before adding it to the skimmer to minimize airborne dust and improve even grid coating.\u003c\/p\u003e\n\n  \u003cp\u003eOnce or twice per season, a full grid cleaning is required. Drain the tank, remove the grid assembly, and clean each grid panel individually. A diluted muriatic acid soak dissolves mineral scale; rinse thoroughly before reinstalling. Inspect each grid for tears or delamination that would allow D.E. powder to bypass the fabric into the pool.

Store the cleaned, dried grid assembly indoors to protect the fabric from freeze-thaw cycles. Drain the tank body completely using the 1.5\" drain and leave the drain open through the winter.

The tradeoff is media management: D.E. powder must be added after each backwash, grids require periodic acid washing, and spent D.E. must be disposed of in compliance with local regulations (discharge to storm drains is restricted in some jurisdictions).

A backwash valve is sold separately. Compatible options include the SP0740DE (Selecta-Flo 2\" SKT), SP0710XR50 (Vari-Flo 1.5\" NPT), SP0715XR50 (Vari-Flo 2\" NPT), and SP0410X5025 (Slide Valve 2\" SKT).\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eHow much D.E. powder does the W3DE4820 need, and how often?\u003c\/summary\u003e\n    \u003cp\u003eThe W3DE4820 requires 6 lbs of pool-grade D.E. powder for the initial charge and after each backwash cycle. Always pre-mix the D.E. into a slurry with water in a bucket before adding it slowly through the skimmer with the pump running. Never add D.E. with the pump off; the powder will settle to the tank bottom rather than coating the grids.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does it mean if D.E. powder appears in the pool?\u003c\/summary\u003e\n    \u003cp\u003eD.E. appearing in the pool as a white or gray cloud or fine dust on the pool floor indicates a torn or damaged grid allowing powder to bypass the fabric. Turn off the pump immediately, disassemble the tank, and inspect each grid panel. A damaged grid must be replaced before adding fresh D.E. and returning the filter to service.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eCan the W3DE4820 use Perlite instead of D.E. powder?\u003c\/summary\u003e\n    \u003cp\u003eYes. Perlite is compatible with the ProGrid's vertical grid design and is used by some pool owners in areas where D.E. disposal is regulated or where the handling of silica-based media is a concern. Dosing amounts and backwash procedures may differ from D.E. Follow the Perlite product manufacturer's guidelines for the correct amount per square foot of filter area.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eHow often does the W3DE4820 need a full grid cleaning?\u003c\/summary\u003e\n    \u003cp\u003eOnce or twice per season is typical for residential installations, usually at pool opening and at the midpoint of heavy use. Routine backwashing handles bulk debris load, but scale, oils, and fine organics that backwashing cannot remove accumulate in the grid fabric over time. A diluted muriatic acid soak of the grid assembly during seasonal cleaning dissolves mineral deposits and restores filtration efficiency.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat vertical clearance is needed to service the W3DE4820?\u003c\/summary\u003e\n    \u003cp\u003eA minimum of 58.1\" of vertical clearance above the filter is required to remove the grid assembly. When planning equipment pad placement, also account for the height of the backwash valve above the tank: add 12\" for a 1.5\" multiport valve, 14\" for a 2\" multiport valve, or 7\" for a 2\" slide valve.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003ch2\u003eHayward W3DE4820 ProGrid D.E.

When pool-grade D.E. powder is added through the skimmer with the pump running, it coats the fabric-covered grid elements inside the tank. Pool water passing through this D.E. cake is filtered to 5 microns on the first pass.\u003c\/p\u003e\n\n  \u003cp\u003eAs the cake loads with debris, operating pressure rises. The filter is serviced by backwashing through a compatible valve, which clears the spent D.E., followed by a fresh 7.5 lb D.E. charge to recoat the grids. Pool-grade D.E. must be used; food-grade and pest-control D.E. products are not appropriate for pool filtration.\u003c\/p\u003e\n\n  \u003ch2\u003eHayward W3DE6020 ProGrid D.E.

Compatible options include the SP0740DE (Selecta-Flo 2\" SKT), SP0710XR50 (Vari-Flo 1.5\" NPT), SP0715XR50 (Vari-Flo 2\" NPT), and SP0410X5025 (Slide Valve 2\" SKT).\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eHow much D.E. powder does the W3DE6020 need, and how often?\u003c\/summary\u003e\n    \u003cp\u003eThe W3DE6020 requires 7.5 lbs of pool-grade D.E. powder for the initial charge and after each backwash cycle. Always pre-mix the D.E. into a slurry with water in a bucket before adding it slowly through the skimmer with the pump running. Never add D.E. with the pump off; the powder will settle to the tank bottom rather than coating the grids.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does it mean if D.E. powder appears in the pool?\u003c\/summary\u003e\n    \u003cp\u003eD.E. appearing in the pool as a white or gray cloud or fine dust on the pool floor indicates a torn or damaged grid allowing powder to bypass the fabric. Turn off the pump immediately, disassemble the tank, and inspect each grid panel.

Perlite is compatible with the ProGrid's vertical grid design and is used by some pool owners in areas where D.E. disposal is regulated or where the handling of silica-based media is a concern.

Routine backwashing handles bulk debris load, but scale, oils, and fine organics that backwashing cannot remove accumulate in the grid fabric over time. A diluted muriatic acid soak of the grid assembly during seasonal cleaning dissolves mineral deposits and restores filtration efficiency.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat vertical clearance is needed to service the W3DE6020?\u003c\/summary\u003e\n    \u003cp\u003eA minimum of 68.125\" of vertical clearance above the filter is required to remove the grid assembly. When planning equipment pad placement, also account for the height of the backwash valve above the tank: add 12\" for a 1.5\" multiport valve, 14\" for a 2\" multiport valve, or 7\" for a 2\" slide valve.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003ch2\u003eHayward W3DE6020 ProGrid D.E.

Pool Filter: No Backwash, No Grid Teardown\u003c\/h2\u003e\n\u003cp\u003eThe PerFlex W3EC65A delivers 2-micron D.E. filtration without the maintenance overhead of a conventional grid-based D.E. filter. Instead of rigid grid panels that need backwashing, fresh D.E. after every cleaning, and periodic acid washing, the PerFlex uses patented Flex-Tubes that clean themselves via a bump handle. When pressure rises, you stop the pump, stroke the bump handle, and restart. The Flex-Tubes compress and release, shedding the spent D.E. cake, which then redistributes and recoats the tubes. No valve, no drain line, no fresh D.E. needed after each cleaning. A single 6 lb charge lasts significantly longer than in a conventional D.E. filter because the powder is reused rather than flushed away.\u003c\/p\u003e\n\u003ch2\u003eHow the PerFlex Bump-to-Clean Cycle Works\u003c\/h2\u003e\n\u003cp\u003eWhen operating pressure rises 10 to 12 PSI above the clean baseline: stop the pump, push the bump handle down slowly then up briskly, repeat 8 times. The Flex-Tubes flex and compress, dislodging the loaded D.E. cake. Dirty and clean D.E. mix together and recoat the tube surfaces. Restart the pump. In most cases pressure returns near baseline and the existing D.E. charge continues filtering without any addition of fresh powder. This cycle can be repeated many times before a full sump drain is needed, and a full D.E. recharge is only required when bumping and draining no longer restore acceptable pressure.\u003c\/p\u003e\n\u003ch2\u003eHayward PerFlex W3EC65A D.E.

The PerFlex uses Flex-Tubes that self-clean through the bump mechanism. Spent D.E. is redistributed and reused rather than flushed away, so no backwash valve, drain line, or grid acid washing is needed. Water clarity is the same; the maintenance difference is significant.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow long does a D.E. charge last?\u003c\/summary\u003e\n\u003cp\u003eSignificantly longer than in a conventional D.E. filter. Because D.E. is reused through the bump cycle rather than discharged and replaced, a single 6 lb charge can run for several months depending on pool size, bather load, and debris conditions. Most PerFlex owners add a full D.E. recharge only one to three times per season rather than after every cleaning.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat D.E. powder do I use?\u003c\/summary\u003e\n\u003cp\u003eStandard pool-grade diatomaceous earth. Do not use food-grade, pest-control, or industrial D.E. products; those are formulated differently and are not appropriate for pool water contact. Perlite is also compatible with the Flex-Tube design as a silica-free alternative.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eD.E. is appearing in my pool. What does that mean?\u003c\/summary\u003e\n\u003cp\u003eD.E. returning to the pool through the return fittings means one or more Flex-Tube elements has a hole or seam failure allowing powder to bypass the filter media. Stop the pump immediately, drain the tank, remove the tube assembly, and inspect each element individually. Replace any tube showing a breach before restarting.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this a direct replacement for the EC65A?\u003c\/summary\u003e\n\u003cp\u003eYes.

Too little flow and the pool does not turn over adequately; too much flow and the filter runs above its rated pressure ceiling, which accelerates D.E. cake loading, shortens service intervals, and puts stress on the flex-tube elements and housing seals. For pool owners without experience in pump curve analysis and hydraulic system design, this is the most common source of equipment performance problems after installation.\u003c\/p\u003e\n\n  \u003cp\u003eThe W3EC40C92S eliminates that risk. The 1.5 HP pump included in this system is factory-tested with the EC40AC filter to confirm that flow, pressure, and D.E. service interval all fall within appropriate ranges for pools up to 20,000 gallons. The pre-configured pump-to-filter connection also eliminates the port-sizing adapter issues that commonly arise when combining separately sourced components.\u003c\/p\u003e\n\n  \u003cp\u003ePool owners who already have a functioning in-ground pump and need only the filter can purchase the standalone EC40AC filter separately and pair it with their existing pump — provided the pump's output at operating head does not exceed the filter's 40 GPM rating.\u003c\/p\u003e\n\n  \u003c!-- ============================================================\n       SECTION 5: How It Works\n  ============================================================ --\u003e\n  \u003ch2\u003eHow the Perflex EC40AC Filter in the W3EC40C92S Maintains Itself Between Full Recharges\u003c\/h2\u003e\n\n  \u003cp\u003eThe 1.5 HP pump in the W3EC40C92S draws pool water through the skimmer and main drain and delivers it to the EC40AC filter. Inside the filter, pool water passes through the D.E.-coated flex-tube elements, which capture particles down to 2–5 microns. Filtered water exits through the outlet and returns to the pool. Over time, the D.E. cake on the tubes accumulates debris and operating pressure rises on the gauge.\u003c\/p\u003e\n\n  \u003cp\u003eWhen pressure climbs 8–10 PSI above the clean baseline, turn off the pump and stroke the bump handle 8 times — down slowly, up briskly. The flex tubes compress and flex, dislodging the loaded D.E. cake into the sump at the base of the filter. The tubes immediately recoat from D.E. still suspended in the water, and restarting the pump typically restores pressure near the clean baseline without adding any new D.E. powder. This bump cycle can be repeated multiple times before the sump needs draining.\u003c\/p\u003e\n\n  \u003cp\u003eWhen bumping no longer restores pressure, drain the sump by opening the drain at the base of the filter, allowing the spent D.E. slurry to discharge fully, and closing it again. If pressure returns near baseline after draining, the existing D.E. charge is still active. Only when both bumping and sump draining fail to restore acceptable pressure is a full 6 lb recharge required.\u003c\/p\u003e\n\n  \u003c!-- ============================================================\n       SECTION 6: Installation Overview\n  ============================================================ --\u003e\n  \u003ch3\u003eInstalling the Hayward Perflex W3EC40C92S – System Placement and Startup Checklist\u003c\/h3\u003e\n\n  \u003cp\u003ePosition the filter and pump on a stable, level equipment pad with clear access to the bump handle on the filter exterior, the sump drain at the filter base, and the pump strainer basket on the front of the pump body. The system connects to the pool's return and suction plumbing through 1-1\/2 in. NPT fittings at the pump inlet and filter outlet. Route the suction line from the pool's skimmer and main drain to the pump inlet, and route the return line from the filter outlet back to the pool's return fittings.\u003c\/p\u003e\n\n  \u003cp\u003eBefore adding D.E., fill the pump strainer basket with water to assist priming. With the pump running, open the manual air relief valve on the filter and hold it open until water flows steadily from the port, confirming the system is fully primed. Then, with the pump still running, slowly add the 6 lb initial D.E. charge as a pre-mixed slurry through the filter inlet. Allow 3–5 minutes of circulation before checking the gauge and recording the clean baseline pressure. The pump must be connected to a dedicated GFCI-protected electrical circuit — do not operate pool pump equipment without GFCI protection regardless of circuit voltage.\u003c\/p\u003e\n\n  \u003c!-- ============================================================\n       SECTION 7: Seasonal Maintenance\n  ============================================================ --\u003e\n  \u003ch2\u003eSeasonal Maintenance and Winterization for the Hayward Perflex W3EC40C92S D.E. Filter System\u003c\/h2\u003e\n\n  \u003cp\u003eAt the end of each swim season, drain the filter sump completely and flush it with clean water. In mild climates where temperatures do not reach hard freeze levels, drain the filter housing fully through the sump drain and air relief valve, drain the pump through its designated drain plugs, and leave all drains open through the off-season to prevent water from collecting in either component.\u003c\/p\u003e\n\n  \u003cp\u003eIn freeze climates, full winterization requires draining both the pump and filter of all water before temperatures drop. Open the clamp housing on the EC40AC filter, remove the flex-tube assembly, rinse it thoroughly, and store it indoors in a dry location to protect the knitted tube material from freeze-thaw damage. Remove the pump drain plugs and any water from the pump pot and volute, and store the pump in a protected, non-freezing location if possible. Water left in either component through a hard freeze cycle can cause cracking that voids the warranty and requires full component replacement.\u003c\/p\u003e\n\n  \u003cp\u003eIn spring, reinstall the pump drain plugs, reinstall the flex-tube assembly in the filter housing, secure the clamp band, and perform a full 6 lb D.E. recharge before opening the pool.

The filter hardware, flex-tube elements, clamp housing, bump handle, sump, and plumbing connections are identical between the two. The W3EC40C92S is the right choice when both a filter and a pump are needed. The standalone EC40AC is the right choice when an existing compatible in-ground pump is already installed and functioning — provided its GPM output at operating head does not exceed the EC40AC's 40 GPM rated flow ceiling.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eIs the W3EC40C92S designed for in-ground or above-ground pools?\u003c\/summary\u003e\n    \u003cp\u003eThe W3EC40C92S is designed and rated for residential in-ground pool applications up to 20,000 gallons. The 1.5 HP pump included in this system is an in-ground pool pump, which differs from above-ground pool pumps in priming design, head ratings, and flow characteristics. For smaller in-ground pools up to 10,000 gallons, the W3EC30AC1 system with the EC30AC filter and 1 HP pump is the more appropriate choice.\u003c\/p\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails\u003e\n    \u003csummary\u003eDoes D.E. powder come included with the W3EC40C92S?\u003c\/summary\u003e\n    \u003cp\u003eNo. The W3EC40C92S system does not include D.E. powder. The initial charge of 6 lbs of pool-grade diatomaceous earth must be purchased separately before the system can be placed in service. Use only pool-grade D.E. — not food-grade, pest-control, or construction-grade products.

Filter System for Above Ground Pools\u003c\/h2\u003e\n  \u003cp\u003eThe W3EC50C93S bundles Hayward's EC50AC PerFlex extended-cycle D.E. filter with a 1.5 HP PowerFlo Matrix above ground pump, a platform base, and all the hose hardware needed to connect to your pool. The PerFlex design uses patented Flex-Tubes instead of rigid D.E. grids. When pressure rises, you stop the pump and stroke the bump handle to clean the filter; the Flex-Tubes flex and shed the loaded D.E., which redistributes and recoats the tubes. No backwash valve, no drain line, no fresh D.E. needed after each cleaning. A single D.E. charge lasts significantly longer than in a conventional grid filter because the powder is reused rather than flushed away.\u003c\/p\u003e\n\n  \u003cp\u003eThe pump and filter are performance-matched at the factory, meaning the 1.5 HP Matrix pump's flow output falls within the EC50AC's rated range at typical above ground pool plumbing resistance. This matters: pairing an undersized pump with a larger filter leaves filtration capacity on the table; pairing an oversized pump can over-pressure the filter and compress service intervals. The W3EC50C93S removes that guesswork.\u003c\/p\u003e\n\n  \u003ch2\u003eWhat Is Included\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eEC50AC PerFlex extended-cycle D.E. filter with clamp-band housing\u003c\/li\u003e\n    \u003cli\u003e1.5 HP PowerFlo Matrix above ground pool pump with industrial-size strainer basket\u003c\/li\u003e\n    \u003cli\u003eModular platform base\u003c\/li\u003e\n    \u003cli\u003eUnion connection\u003c\/li\u003e\n    \u003cli\u003eTwo 1.5\" x 6 ft filter hoses, hose adapters, and hose clamps\u003c\/li\u003e\n    \u003cli\u003ePressure gauge and manual air relief valve (installed on filter)\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \u003cdiv class=\"note\"\u003eD.E. powder is not included.
