The spring-loaded disc mechanism closes automatically when flow stops or reverses, protecting equipment and system integrity without manual intervention. Built from PVC, this valve is suited for corrosive or non-petroleum fluid applications where metal valves would degrade. Plumbers and pipefitters install this valve in residential and light commercial piping systems as a backflow prevention device.\u003c\/p\u003e\n\u003cp\u003eThis check valve is used in water supply, irrigation, chemical feed, and pool or spa plumbing lines where backflow could contaminate supply lines or damage pumps and equipment. The 3\/4-inch size fits standard residential and small commercial pipe runs. It is appropriate for systems where flow direction must be maintained automatically without relying on manual shut-off procedures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpring-loaded mechanism provides automatic closure on flow reversal or loss of pressure\u003c\/li\u003e\n  \u003cli\u003ePVC construction resists corrosion in water, irrigation, and chemical piping applications\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch pipe size fits common residential and light commercial plumbing configurations\u003c\/li\u003e\n  \u003cli\u003eInline installation design simplifies integration into existing pipe runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation check valve for 3\/4-inch PVC piping systems in residential and light commercial plumbing, irrigation, and pool or spa applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before cutting into any existing line. Observe the flow direction arrow marked on the valve body to ensure correct orientation. Solvent-cement connections to PVC pipe should use the appropriate primer and cement rated for the service fluid and temperature.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Spring Check Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: PVC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 032888016040\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MUELLER INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 101-604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MUELLER INDUSTRIES","offers":[{"title":"Default Title","offer_id":51383077536050,"sku":"101-604","price":32.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312671611.jpg?v=1782587397","url":"https:\/\/voomisupply.com\/products\/mueller-industries-101-604-pvc-spring-check-valve-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
