When system pressure or temperature exceeds safe operating thresholds, the valve opens automatically to discharge water and relieve the hazard. The inlet and outlet connections are both 3\/4 inch female thread, and the probe length is 4.625 inches. Licensed plumbers and HVAC technicians install this valve as a required safety device on water heating equipment.\u003c\/p\u003e\u003cp\u003eThis relief valve is suited for residential and light commercial water heater and boiler installations where ASME-rated safety devices are required. The 1912 MBH ASME rating covers high-capacity water heating applications. The 3\/4 inch female-by-female configuration fits standard tank and heat exchanger tappings.

Shut off the water supply and allow the system to cool before replacing this valve. Connect a properly sized discharge pipe to the valve outlet, directing it to a safe drain point as required by code. Never cap or plug the discharge outlet, and do not test the valve by lifting the lever unless the system is ready for water discharge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eASME Rating\u003c\/strong\u003e: 1912 MBH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet to Outlet Connection\u003c\/strong\u003e: 3\/4 inch Female x 3\/4 inch Female\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProbe Length\u003c\/strong\u003e: 4.625 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CAMPBELL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: L100277759\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CAMPBELL","offers":[{"title":"Default Title","offer_id":51342973731122,"sku":"L100277759","price":209.41,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/100277759.jpg?v=1782012433","url":"https:\/\/voomisupply.com\/products\/campbell-l100277759-temperature-pressure-relief-valve-150-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
