{"product_id":"pentair-tr140c-lower-pipe-assembly","title":"Pentair TR140C Lower Pipe Assembly","description":"\u003cp data-path-to-node=\"0\"\u003eThe Pentair Triton TR140C Lower Pipe Assembly (primarily designated as part number \u003cb data-path-to-node=\"0\" data-index-in-node=\"83\"\u003e154489\u003c\/b\u003e for standard TR140\/TR140C configurations, or \u003cb data-path-to-node=\"0\" data-index-in-node=\"135\"\u003e154010\u003c\/b\u003e for commercial TR140C-3 heavy-duty plumbing matrices) is a critical internal fluid-distribution conduit engineered exclusively for the lower basin infrastructure of Pentair Triton II and Triton C commercial series side-mount high-rate sand filtration systems.\u003c\/p\u003e\n\u003cp data-path-to-node=\"1\"\u003eInjection-molded from a heavy-walled, high-impact, and chemically inert polymer compound, this rigid manifold branch pipe links the central vertical internal plumbing column directly to the lower horizontal lateral hub assembly. Measuring approximately 17.5 inches in length, 7.5 inches in width, and 2.75 inches in height, its primary operational role is to safely handle massive volumes of incoming water, directing the high-velocity fluid downward across the sand bed.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eDuring the normal pool filtration cycle, it serves as the final path ensuring that clear, media-free water collected by the slotted laterals is channeled smoothly out through the bottom tank bulkhead and back to the pool return plumbing. Conversely, during high-velocity backwash cycles, it manages the reversed, turbulent flow of pressurized water needed to lift and expand the silica sand matrix, flushing away deeply trapped organic matter.\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003eThis robust architecture allows the internal plumbing core to safely sustain continuous system operating pressures up to 50 PSI without weeping, hairline cracking, or experiencing joint separation under heavy pump vibration surges. Built to remain permanently submerged beneath hundreds of pounds of dense silica sand in a harsh, chemical-laden framework, its rugged composite design completely resists material deformation, stress-cracking, and corrosive breakdown from high-strength pool sanitizers like chlorine, bromine, and winterizing acid washes. Due to its solid, thick-walled cylindrical geometry tailored for high-volume commercial flow rates, this individual lower piping assembly carries a net product weight of approximately \u003cb data-path-to-node=\"3\" data-index-in-node=\"738\"\u003e1.60 to 1.80 pounds\u003c\/b\u003e, with commercial versions scaling up to a shipping weight of \u003cb data-path-to-node=\"3\" data-index-in-node=\"819\"\u003e4.40 pounds\u003c\/b\u003e.\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53416213643375,"sku":"154010","price":273.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/154010.webp?v=1782745441","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-tr140c-lower-pipe-assembly","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
