Stenner lists it for the 45, 85, 100 and 170 Series adjustable and fixed pumps, and for the SVP and BDF Series pumps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it sits\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe injection check valve is the last piece in the feed line, threaded into the pipe where the chemical goes in. Two jobs: it delivers the dose into the flow, and its internal check stops pressurized water from travelling back up the tubing toward the pump when the pump is idle.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy it wears out\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eEverything the pump feeds passes through this one fitting, so it takes the full strength of the chemical along with line pressure and, on hard water, scale. A valve that weeps at the pipe, will not hold a prime, or feels gritty when it seats has done its time. Match the ferrule size to your tubing before ordering, since the same valve is built in several sizes.\u003c\/p\u003e","brand":"Stenner","offers":[{"title":"Default Title","offer_id":48634170114260,"sku":"GHS-451-4038","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/GHS-451-4038-_1a.png?v=1788826164","url":"https:\/\/www.activepoolsupply.com\/products\/stenner-pumps-ucinj38-injection-check-valve-with-3-8-inch-ferrule","provider":"Active Pool Supply","version":"1.0","type":"link"}
