{"product_id":"extendable-backwater-valve-kit-3-in-pvc-body","title":"Extendable Backwater Valve Kit - 3\" - PVC Body","description":"\u003cp\u003eClean Check® extendable backwater valves prevent sewage backup into a residence or building as a result of a plugged sewer system, excess volume in the system or groundwater flooding. They are designed to be installed easily outside a home, business or other structure, without using a costly manhole and are readily accessible for maintenance or cleaning. The extendable valves consist of a tee-shaped valve body, a top collar and a bottom collar with a replaceable PVC flapper attached. In the event of back-pressure, the flapper blocks the reverse flow and prevents a sewage backup. Clean Check® valves are available in ABS and PVC and in multiple sizes, to meet the needs of most residential and commercial construction. Vertical offset from upstream to downstream side is: 3 in and 4 in valves - 0.4 in, 6 in valve - 1\/2 in.\u003c\/p\u003e","brand":"CLEAN CHECK","offers":[{"title":"Default Title","offer_id":53407583797537,"sku":"97033","price":177.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0943\/1905\/1041\/files\/RectorSeal_96931_1245b6c7-94de-4c6a-bc13-b2f38bd8d7e0.jpg?v=1790122815","url":"https:\/\/standardvmi.com\/products\/extendable-backwater-valve-kit-3-in-pvc-body","provider":"Standard Plumbing Supply","version":"1.0","type":"link"}
