This original equipment manufacturer (OEM) part is engineered explicitly to mount within the upper dome region of Pentair THS Series \"Smoothie\" high-rate horizontal sand filtration systems—specifically configured for the 42-inch diameter by 72-inch long vessel (model THS4272).\u003c\/p\u003e\n\u003cp data-path-to-node=\"1\"\u003eFabricated from thick-walled, commercial-grade Schedule 80 PVC and high-impact engineering polymers, this wide-set horizontal branch assembly interfaces directly with the filter tank's primary 6-inch flanged inlet bulkhead. Its primary operational role is to receive high-velocity, raw unfiltered pool water and uniformly diffuse it across the expansive 19.7 square foot surface area of the sand bed. The manifold pipe framework features a series of calculated distribution nozzles and diffuse ports that scatter the incoming water stream evenly, completely preventing hydraulic dead-zones, localized media churning, or destructive \"tunneling\"—where high-velocity water cuts direct channels through the 2,210 pounds of silica sand and 700 pounds of gravel.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eBy balancing the incoming fluid velocity, this internal distribution grid allows the filtration system to maximize its commercial turnover capacity (up to 295 GPM at standard commercial ratings) while safely sustaining a continuous maximum working pressure profile of 50 PSI. Built to survive decades permanently enclosed within a harsh, pressurized chemical vessel, its robust Schedule 80 PVC framework resists material warping, solvent-joint fatigue, and advanced oxidation from constant exposure to high-strength sanitizers like liquid chlorine, bromine, and routine scale-removing acid flushes. Due to its large 6-inch main footprint, thick reinforcement walls, and expansive multi-branch configuration, this heavy commercial influent manifold carries a substantial product and shipping weight of approximately \u003cb data-path-to-node=\"2\" data-index-in-node=\"815\"\u003e32.00 to 36.50 pounds\u003c\/b\u003e.\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53720762646639,"sku":"IM-THS72","price":2011.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/616nC5dUwZL_b6e53b6d-20d6-4e5a-ac59-a4f6c6b3287f.jpg?v=1783437651","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-42-x-72-smoothie-influent-manifold","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
