There is no multiport valve, no backwash port, and no drain line required. Routine cleaning is done by removing and rinsing the cartridge by hand.\u003c\/p\u003e\n \u003c\/details\u003e\n\n \u003cdetails\u003e\n \u003csummary\u003eWhat does the built-in check valve do?\u003c\/summary\u003e\n \u003cp\u003eThe check valve prevents pool water from draining out of the system when the cartridge is removed for cleaning. This means the pump strainer basket and plumbing stay primed during cartridge service, and no re-priming is needed when the filter is reassembled and the pump is restarted.\u003c\/p\u003e\n \u003c\/details\u003e\n\n \u003cdetails\u003e\n \u003csummary\u003eCan the filter head be rotated after installation?\u003c\/summary\u003e\n \u003cp\u003eYes. The filter head is designed to rotate so you can orient the pressure gauge and manual air relief valve in any direction.

Continue until the runoff is clear. Do not use a pressure washer at any setting; high-pressure spray permanently compresses the pleat fibers. Reinstall the cartridge, close the EasyLok ring, open the air relief valve, and restart the pump. Note the pressure when the system is running cleanly; this is the baseline for future cleaning decisions.

The W3C150S is positioned for smaller and mid-size pools, spas, and water features, while the older C150S was rated for larger in-ground pools. If you are replacing an existing C150S, verify connection sizes and footprint before ordering.\u003c\/p\u003e\n \u003c\/details\u003e\n\n \u003cdetails\u003e\n \u003csummary\u003eDoes the W3C150S require any tools for cartridge removal?\u003c\/summary\u003e\n \u003cp\u003eNo. The EasyLok ring design provides single-turn access to all internal components without tools. The only step required before opening is turning off the pump and releasing tank pressure through the air relief valve.

A filter with lower head loss allows the pump to achieve the required flow rate at a lower speed or for a shorter run time, which reduces electricity consumption.

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.

Continue until the runoff is clear. 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 reversed.\u003c\/p\u003e\n\u003ch3\u003eDeep Soak Cleaning and Element Replacement\u003c\/h3\u003e\n\u003cp\u003eSurface rinsing clears the bulk debris load but does not remove oils, mineral scale, and fine organic compounds that accumulate in 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.\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. Each element is 131 sq ft (7\" outer diameter, 32.875\" length). A full replacement set requires four CX1280XRE units.

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.

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. Dosing amounts and backwash procedures may differ from D.E.

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 W3DE3620?\u003c\/summary\u003e\n \u003cp\u003eA minimum of 50.1\" 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 W3DE3620 ProGrid D.E.

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.

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.

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\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. 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\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.

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.

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 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. 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 W3DE6020 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 W3DE6020 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 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.

Instead of rigid grid panels that require 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 redistributes and recoats the tubes. No valve, no drain line, no fresh D.E. required after each cleaning.

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.\u003c\/p\u003e\n \u003c\/details\u003e\n\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.

Pressure typically returns near baseline and the existing charge continues filtering.

The larger filter area means longer intervals between bump cycles, lower sustained operating pressure, and more headroom for high-output pumps. If your pump output approaches or exceeds 67 GPM, the W3EC75A is the correct choice.\u003c\/p\u003e\n \u003c\/details\u003e\n\n \u003cdetails\u003e\n \u003csummary\u003eHow often does the D.E. charge need replacing?\u003c\/summary\u003e\n \u003cp\u003eSignificantly less often than in a conventional D.E. filter. Because the bump mechanism reuses D.E. rather than flushing it, a single 7 lb charge typically lasts several months under normal conditions.

Consult a pool equipment professional for system design guidance.\u003c\/p\u003e\n\u003ch2\u003eHow the Hayward XStream W3CC15093S Cartridge Filter System Works\u003c\/h2\u003e\n\u003cp\u003eThe PowerFlo Matrix pump draws water from the pool through the skimmer and main drain and pushes it through the filter inlet into the XStream tank. Water passes through the pleated polyester CX150XRE cartridge element, where particles down to 10-15 microns are physically trapped in the pleat structure. Filtered water exits through the outlet and returns to the pool. No chemicals, no media recharge, and no backwash valve are involved.\u003c\/p\u003e\n\u003cp\u003eThe cartridge accumulates debris over time and operating pressure on the gauge gradually rises. When the gauge reads 8 to 10 PSI above the clean baseline recorded at startup, turn off the pump, open the air relief valve to depressurize the housing, and use the EasyLok ring to access the cartridge in a single turn. Rinse the element thoroughly from top to bottom between each pleat fold with a garden hose, reinstall, and restart the pump. The process takes around 10 to 15 minutes and requires no tools.\u003c\/p\u003e\n\u003ch3\u003eCartridge Cleaning and Replacement for the W3CC15093S\u003c\/h3\u003e\n\u003cp\u003eFor typical above-ground pool seasonal use, cleaning every two to four weeks during peak summer months is standard. Pools with heavy bather loads or nearby vegetation may need more frequent attention. A deep soak in pool cartridge cleaning solution at season opening and midpoint removes oils and mineral deposits that hose rinsing alone does not clear, and significantly extends cartridge service life.\u003c\/p\u003e\n\u003cp\u003eReplace the CX150XRE cartridge when post-cleaning pressure does not return to the established baseline, when the pleat material shows visible tears or deformation, or when the end caps show cracking. Always use the OEM Hayward CX150XRE replacement to ensure correct fit in the XStream housing.\u003c\/p\u003e\n\u003ch3\u003eInstalling the W3CC15093S and Matching Electrical Requirements\u003c\/h3\u003e\n\u003cp\u003ePlace the unit on a stable, level surface within reach of the pool's return and suction hose fittings and within safe distance of a GFCI-protected electrical circuit. The pump accepts 115V or 230V depending on the motor wiring configuration; refer to the label on the pump motor for the correct setup. Never connect pool pump equipment to a circuit without GFCI protection. After connecting the hoses, fill the pump strainer basket with water to assist priming, install the cartridge, close the EasyLok lid, and start the pump with the air relief valve open until water flows steadily. Record the gauge reading at that point as the clean baseline.\u003c\/p\u003e\n\u003ch3\u003eWinterizing the W3CC15093S\u003c\/h3\u003e\n\u003cp\u003eAt season end, remove the CX150XRE cartridge, rinse and inspect it, and store it indoors away from freezing temperatures and direct sunlight. Drain both the pump pot and filter housing completely; remove the pump drain plugs and open the filter air relief valve to allow all residual water to escape. Store the unit in a non-freezing location. Leaving water in either housing through a freeze cycle risks cracking the plastic, which is not covered under warranty.\u003c\/p\u003e\n\u003ch2\u003eHayward W3CC15093S XStream Cartridge Filter System Frequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs the W3CC15093S designed for above-ground or in-ground pools?\u003c\/summary\u003e\n\u003cp\u003eAbove-ground only.

Although sold as an integrated system, the pump and filter are discrete components. If the pump motor fails but the filter is in good condition, the pump can be replaced with a compatible above-ground pool pump without replacing the filter housing.

Tank, sand capacity, filtration area, and flow rate are identical. Choose the W3S270T2 when your plumbing is 2-inch throughout, your pump output is near the 75 GPM ceiling, or you are replacing a system originally plumbed with a 2-inch valve.\u003c\/p\u003e\n \u003c\/details\u003e\n\n \u003cdetails\u003e\n \u003csummary\u003eDoes a larger valve increase the filter's flow rate?\u003c\/summary\u003e\n \u003cp\u003eNo. The design flow rate is 75 GPM regardless of valve size. The 2-inch valve reduces head loss through the valve body itself, meaning the pump works slightly less hard to push water through the system at high flow rates.
