It uses the same compact body as the Matrix 1 HP, with a horizontal\/vertical discharge that switches orientation with a button press. Upgrading from 1 HP to 1.5 HP is a direct pump swap with no plumbing changes. The only thing to verify before the swap is the electrical circuit; the 1.5 HP requires a 20-amp circuit versus the 15 amps the 1 HP needs.\u003c\/p\u003e\n\u003ch2\u003eHayward PowerFlo Matrix 1.5 HP vs. 1 HP: Which Do You Need?\u003c\/h2\u003e\n\u003cp\u003eThe 1 HP handles pools up to roughly 18,000 gallons on a standard 8 to 10 hour daily run. Once pool volume approaches 20,000 gallons, or the plumbing adds friction through longer hose runs or multiple fittings, the 1 HP starts running near its ceiling, which increases thermal overload events on hot days and slows recovery after heavy bather use. The 1.5 HP provides headroom that keeps the motor comfortable even on a large pool with a suction-side cleaner running simultaneously. The 1.5 HP also draws 14.2A vs. 10.8A for the 1 HP, so confirm your outdoor circuit is 20 amps before ordering.\u003c\/p\u003e\n\u003ch2\u003eHayward PowerFlo Matrix 1.5 HP W3SP1593 - Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ccaption\u003eHayward PowerFlo Matrix 1.5 HP Above Ground Pool Pump W3SP1593 - Full Specifications\u003c\/caption\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\"\u003eSpecification\u003c\/th\u003e\n\u003cth scope=\"col\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU \/ Model\u003c\/td\u003e\n\u003ctd\u003eW3SP1593\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor Horsepower\u003c\/td\u003e\n\u003ctd\u003e1.5 HP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpeed Type\u003c\/td\u003e\n\u003ctd\u003eSingle speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor RPM\u003c\/td\u003e\n\u003ctd\u003e3450 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e115V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAmperage\u003c\/td\u003e\n\u003ctd\u003e14.2A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit Required\u003c\/td\u003e\n\u003ctd\u003eDedicated 20-amp GFCI-protected outdoor circuit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDischarge Orientation\u003c\/td\u003e\n\u003ctd\u003eHorizontal\/vertical (switchable with button press)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePort Size\u003c\/td\u003e\n\u003ctd\u003e1.5\" and 2\" connections\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax Flow Rate\u003c\/td\u003e\n\u003ctd\u003eApprox. 53 GPM at low head\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBasket Access\u003c\/td\u003e\n\u003ctd\u003eFront-access strainer basket\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePool Application\u003c\/td\u003e\n\u003ctd\u003eAbove ground pools above ground pools\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBody Material\u003c\/td\u003e\n\u003ctd\u003eCorrosion-resistant polymer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eUL Listed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e1 year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cdiv class=\"note\"\u003eSpecifications are subject to manufacturer revision.

The W3SP1593 uses the same body dimensions, port positions, and connection sizes as the Matrix 1 HP. An existing 1 HP Matrix installation can be upgraded to the 1.5 HP by swapping the pump body and connecting to the same hose fittings already in place. Verify the electrical circuit is rated for 20 amps before making the swap; the 1.5 HP requires 20 amps versus the 15 amps adequate for the 1 HP.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat circuit do I need for the PowerFlo Matrix 1.5 HP?\u003c\/summary\u003e\n\u003cp\u003eA dedicated 20-amp GFCI-protected outdoor circuit. The pump draws 14.2A at full load; running it on a 15-amp circuit will cause the breaker to trip under sustained load. If your pool area currently has only a 15-amp outlet, upgrading the circuit breaker and outlet to 20 amps is required before installing this pump.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWill my existing filter handle the 1.5 HP's flow rate?\u003c\/summary\u003e\n\u003cp\u003eCheck it. A filter sized for a 1 HP pump will run at elevated pressure under the 1.5 HP's higher flow rate, which restricts filtration and shortens filter media life. For a 20,000-gallon pool, an above ground sand filter with a 19 to 22 inch tank diameter rated for 45 to 55 GPM is appropriate for the Matrix 1.5 HP's output.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat timer works with this pump?\u003c\/summary\u003e\n\u003cp\u003eA standard plug-in outdoor pool timer rated for 20 amps at 115V. Confirm the timer's amperage rating before connecting; a 15-amp timer is undersized for the 1.5 HP's 14.2A draw and can overheat under sustained load. Mechanical dial-style pool timers are the most common and reliable choice for above ground pump control.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow does the Matrix 1.5 HP compare to the PowerFlo LX 1.5 HP?\u003c\/summary\u003e\n\u003cp\u003eBoth are Hayward above ground pumps at 1.5 HP and 115V with comparable flow rates. The difference is physical layout. The Matrix has a side-discharge port and front-access basket in a compact low-profile body, which suits tight installations and horizontal filter connections. The PowerFlo LX has a larger footprint, top-load basket, and top or angled discharge, which suits open installations where basket capacity and easier access are priorities. Choose based on your installation layout, not horsepower; they produce similar flow at the same head pressure.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdiv aria-label=\"Hayward PowerFlo Matrix 1.5 HP Above Ground Pool Pump W3SP1593 Manual and Warranty Info\" role=\"complementary\" class=\"doc-links\"\u003e\n\u003ch2\u003eHayward PowerFlo Matrix 1.5 HP Above Ground Pool Pump W3SP1593 Manual and Warranty Info\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca rel=\"noopener\" href=\"\/files\/hayward-powerflo-matrix-1-5hp-w3sp1510-owners-manual.pdf\" target=\"_blank\"\u003eHayward PowerFlo Matrix 1.5 HP W3SP1593 - Owner's Manual (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca rel=\"noopener\" href=\"\/files\/hayward-powerflo-matrix-1-5hp-w3sp1510-installation-guide.pdf\" target=\"_blank\"\u003eHayward PowerFlo Matrix 1.5 HP W3SP1593 - Installation Guide (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cscript type=\"application\/ld+json\"\u003e\n  {\n    \"@context\": \"https:\/\/schema.org\/\",\n    \"@type\": \"Product\",\n    \"name\": \"Hayward PowerFlo Matrix 1.5 HP Above Ground Pool Pump W3SP1593\",\n    \"brand\": {\n      \"@type\": \"https:\/\/schema.org\/Brand\",\n      \"name\": \"Hayward\"\n    },\n    \"sku\": \"W3SP1593\",\n    \"description\": \"Hayward PowerFlo Matrix 1.5 HP single-speed above ground pool pump.
