One part covers the 0.5 HP through 1.5 HP models.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat the diffuser does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eInside the wet end, the impeller throws water outward and the diffuser is the shaped housing that catches it and turns that motion into usable pressure. When the diffuser is cracked, worn at the eye, or no longer sealing against the impeller, water slips back around instead of going out to the filter. The pump sounds normal, the motor draws normal current, and the pressure is simply down.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eOrdering notes\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is a Val-Pak aftermarket part, not a factory Pentair one, made to the same fitment. Unlike the impellers, which are matched to a specific horsepower, this diffuser is listed across the half through one and a half horsepower Ultra-Flow range. If the impeller is scored or the vanes are worn, replace both while the wet end is open.\u003c\/p\u003e","brand":"Val-pak","offers":[{"title":"Default Title","offer_id":48627762823380,"sku":"VAL-101-3006","price":44.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_7911eca3-14f5-4b2e-944d-e23ee4932e53.jpg?v=1788727834","url":"https:\/\/www.activepoolsupply.com\/products\/diffuser-5hp-1-5hp","provider":"Active Pool Supply","version":"1.0","type":"link"}
