This valve serves as the downstream shutoff in a reduced-pressure zone or double-check valve assembly, allowing technicians to isolate the assembly during annual testing and servicing. The tapped port accepts a standard test cock fitting, giving certified backflow testers direct access to system pressure points without disassembling the line. Licensed plumbers and backflow prevention specialists are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThis shutoff valve is used in commercial and residential plumbing systems where backflow prevention assemblies require periodic certification testing. It is positioned as the second shutoff in a backflow preventer assembly, upstream of the downstream shutoff station. The tapped test cock port makes this valve compatible with standard backflow test kit connections used during annual certification procedures required by most local water authorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTapped port accommodates a standard test cock fitting for backflow assembly testing\u003c\/li\u003e\n\u003cli\u003eFunctions as the second shutoff valve in a backflow prevention assembly\u003c\/li\u003e\n\u003cli\u003eDesigned for use with the 975XL2 backflow preventer series\u003c\/li\u003e\n\u003cli\u003eSupports isolation of the assembly without interrupting the full system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement second shutoff valve for use with the ZURN 975XL2 backflow prevention assembly series.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or certified backflow prevention technician in accordance with local plumbing codes and IPC requirements. Shut off the water supply and depressurize the line before removing or installing any backflow assembly component. Verify that the test cock port is properly plugged or fitted before returning the assembly to service. Do not overtighten fittings at the tapped port, as this can damage the threads and compromise the test connection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Second shutoff valve tapped for test cock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Assembly\u003c\/strong\u003e: 975XL2 backflow preventer\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ZURN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2-850TXL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ZURN","offers":[{"title":"Default Title","offer_id":51233729708338,"sku":"2-850TXL","price":295.42,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307612150.jpg?v=1780107656","url":"https:\/\/voomisupply.com\/products\/zurn-2-850txl-second-shutoff-valve-test-cock","provider":"Voomi Supply","version":"1.0","type":"link"}
