Identified under the LF174A-150 series designation, this valve automatically discharges water when system pressure exceeds its set threshold, preventing equipment damage and potential hazard conditions. The lead-free construction meets current drinking water compliance requirements. Licensed plumbers and mechanical contractors install this type of relief valve during new construction and service calls on water heaters, boilers, and storage tanks where pressure management is a code requirement.\u003c\/p\u003e\n\u003cp\u003eThis valve is sized at 3\/4 inch and is suited for residential and light commercial potable water systems. It is a direct-acting pressure relief valve intended for installation on water heating equipment, expansion tanks, or pressure vessels where ASME-rated protection is required. The LF174A-150 series designation indicates compliance with ASME standards applicable to hot water supply and heating equipment. Installers typically fit this valve at or near the appliance in accordance with local plumbing and mechanical codes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-inch valve size suitable for standard residential and light commercial water heating applications\u003c\/li\u003e\n  \u003cli\u003eASME-rated construction meets code requirements for pressure relief on water heating equipment\u003c\/li\u003e\n  \u003cli\u003eLead-free design complies with current safe drinking water regulations\u003c\/li\u003e\n  \u003cli\u003eLF174A-150 series designation for straightforward specification and replacement sourcing\u003c\/li\u003e\n  \u003cli\u003eAutomatic pressure-activated discharge protects equipment from overpressure conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation pressure relief valve for 3\/4-inch ASME-rated water heating and plumbing pressure vessel 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 ASME requirements. Shut off water supply and relieve system pressure before removing any existing relief valve. Do not cap, plug, or restrict the discharge outlet of the valve at any time. Ensure the discharge line is routed to a safe, code-compliant termination point as required by the applicable plumbing code.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: LF174A-150\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRating\u003c\/strong\u003e: ASME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 30.50 pounds\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: WATTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: f121484\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WATTS","offers":[{"title":"Default Title","offer_id":51233211482418,"sku":"F121484","price":334.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307634001.jpg?v=1780094300","url":"https:\/\/voomisupply.com\/products\/watts-f121484-water-pressure-relief-valve-3-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
