Designed specifically as an internal snap-fit baffling ring for Pentair and PacFab 1.5-inch top-mount and side-mount six-position multiport backwash valves—commonly paired with residential Sand Dollar® and Tagelus® filters—this part sits positioned immediately beneath the main diverter rotor assembly. Injection-molded from a high-impact, chemically inert engineering polymer, its primary hydraulic function is to break up high-velocity water streams arriving from the pool pump, evenly dispersing the flow into designated valve channels during cycles like Filter, Backwash, and Rinse. This precise diffusion prevents localized turbulence from churning up the sand bed inside the filter tank, maximizing debris retention while protecting internal plumbing seals from premature wear caused by continuous hydraulic surges at operating line pressures up to 50 PSI. The component features a highly resilient, non-corrosive structure that offers total immunity to aggressive pool sanitizers, concentrated chlorine shock, and heavy mineral scaling. The physical dry weight of this single Pentair 1.5\" HiFlow Valve Diffuser is approximately \u003cb data-path-to-node=\"0\" data-index-in-node=\"1367\"\u003e0.05 pounds\u003c\/b\u003e (roughly 0.80 ounces, with a packaged shipping weight of approximately 0.10 pounds), providing pool professionals and DIY homeowners with a lightweight, indispensable, and highly durable internal hardware standard for efficient water circulation control.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!----\u003e\n\u003c\/div\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53180148252783,"sku":"271163Z","price":49.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/271163__63450.jpg?v=1780410504","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-1-5-hiflow-valve-diffuser","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
