It is rated to 150 psi and up to 210°F. This model is certified lead-free for potable-water installations.\u003c\/p\u003e\u003cp\u003eThis 1\/2 inch lead free temperature and pressure relief valve is designed to provide automatic temperature and pressure protection to hot water supply tanks and hot water heaters up to 15,000 BTU per hour. This two in one relief valve provides a proven and cost effective means to protect against excessive temperature and pressure emergency conditions. It features a lead free copper alloy body construction, NPT male inlet and NPT female outlet connections, a unique extended thermostat with special thermo-bonded coating and test lever. The temperature relief is 210 degrees (99 degrees C) and the pressure relief is set at 10 psi (8.6 bar).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLead free copper alloy body construction\u003c\/li\u003e\n\u003cli\u003eExtension thermostat with special thermo-bonded coating\u003c\/li\u003e\n\u003cli\u003eStainless steel spring\u003c\/li\u003e\n\u003cli\u003eCSA listed\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\u003cdl\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat pressure is this valve set to?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eIt is factory set to relieve at 125 psi and 210°F. The setting is fixed and is not field-adjustable. Note the 150 psi figure in the specifications is the maximum of the series' pressure range — the ceiling the body is built for, not this valve's relief point. This valve opens at 125 psi. Match it to the appliance nameplate: the relief setting must not exceed the working pressure stamped on the vessel you are protecting.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWill it fit my water heater — what BTU input does it cover?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThis valve is rated for 15,000 BTU\/hr on the CSA temperature-steam basis. Code requires the relief valve's discharge capacity to equal or exceed the input of the appliance it protects, so the number on your heater or boiler nameplate must be at or below that figure. Compare it against the input rating on the water heater's data plate.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eIs this ASME rated?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. It is ASME rated and carries the \"HV\" code symbol under ASME BPVC Section XIII (the section that replaced Section IV for overpressure protection), and it is National Board (NBBI) certified. It is also ANSI Z21.22 \/ CSA 4.4 approved, which is the listing water heater relief valves are required to carry. Inspectors look for that stamp on the valve body, and it is there.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eCan I use this on potable water?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. It is certified lead-free to NSF\/ANSI 372, which is what plumbing codes require for any device in a drinking-water line.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes the discharge have to be piped?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eYes. Codes require the outlet to be piped full-size to a safe point of discharge, terminating with an air gap and no valve, cap, or reducer anywhere in the line — a relief valve that cannot discharge freely is not protecting anything. The manual test lever should be operated at least annually to confirm the valve is not seized.\u003c\/dd\u003e\n\u003c\/dl\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Relief\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Pressure (psi):\u003c\/strong\u003e 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity:\u003c\/strong\u003e 25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United States\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1 Year Limited\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e LF1XL 125-210 1\/2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature:\u003c\/strong\u003e up to 210°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e ASME Section XIII (HV), NBBI, ANSI Z21.22, CSA 4.4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead-Free:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Type:\u003c\/strong\u003e Temperature \u0026amp; Pressure\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory Set Pressure (psi):\u003c\/strong\u003e 125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Setting (°F):\u003c\/strong\u003e 210\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDischarge Capacity (BTU\/hr):\u003c\/strong\u003e 15000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBTU Rating Basis:\u003c\/strong\u003e CSA Temperature Steam\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eASME Code Rating:\u003c\/strong\u003e ASME Section XIII (HV)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Residential Water Heater\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length:\u003c\/strong\u003e Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Configuration:\u003c\/strong\u003e MNPT inlet x FNPT outlet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Reseating:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManual Test Lever:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproved for Potable Water:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSentryPlus Alert Flood Sensor:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Watts","offers":[{"title":"Default Title","offer_id":54935738810667,"sku":"0121324","price":75.54,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0277\/3168\/9577\/files\/061a36f3f53746d38a10353152193007d569f2ea_266330d9-bb66-4a4e-a2e3-02a6cb5f5ac5.jpg?v=1785985398","url":"https:\/\/citysupplygroup.com\/products\/watts-0121324","provider":"City Supply","version":"1.0","type":"link"}
