It features a brass body. Rated to 150 psi.\u003c\/p\u003e\u003cp\u003eThis 3\/4 inch pressure relief valve is used in residential applications to protect against excessive pressure on domestic storage tanks and tankless water heaters. It consists of a brass body construction with NPT threaded male inlet and NPT threaded female (drain) outlet, test lever, and stainless steel spring. It is ANSI Z21.22 approved, ASME rated and design certified and listed by CSA. The pressure relief is set at 75 psi (5.2 bar).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBrass body construction\u003c\/li\u003e\n\u003cli\u003ePressure relief is set at 75 psi (5.2 bar)\u003c\/li\u003e\n\u003cli\u003eTest lever included\u003c\/li\u003e\n\u003cli\u003eASME rated and CSA certified\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 75 psi. 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 75 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\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\u003eNo. This model is not certified lead-free, so it cannot be installed in a potable (drinking) water line under the NSF\/ANSI 372 weighted-average lead rule. Use it on non-potable service, or order the \"LF\" version of this model for potable water.\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\u003eSize:\u003c\/strong\u003e 3\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size:\u003c\/strong\u003e 3\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size:\u003c\/strong\u003e 3\/4\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e Brass\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 50\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 3L-075 3\/4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e ASME Section XIII (HV), ANSI Z21.22, CSA 4.4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead-Free:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Type:\u003c\/strong\u003e Pressure Only\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory Set Pressure (psi):\u003c\/strong\u003e 75\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 Tankless \/ Thermal Expansion\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\u003eManual Test Lever:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApproved for Potable Water:\u003c\/strong\u003e No\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":54935746085163,"sku":"0011086","price":152.74,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0277\/3168\/9577\/files\/21e7127e1213b4d2597e7f9678cc4bec27f502af_61d5ab3b-a8a8-49a3-b831-8129864f3ce0.jpg?v=1785985559","url":"https:\/\/citysupplygroup.com\/products\/watts-0011086","provider":"City Supply","version":"1.0","type":"link"}
