If pressure inside the heater rises past the valve setting, whether from a closed valve downstream, a blocked line or a heater firing with no flow, the relief valve opens and lets it out. Everything else in the system assumes that valve works.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA relief valve that has lifted once often will not seat again cleanly, and one that has been sitting in pool water for years can corrode internally. A weeping or dripping valve is telling you it is finished. It is not a part to adjust, plug or leave for later. Confirm the port size and the valve part number on your heater before ordering.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48627344015572,"sku":"PUR-151-2403","price":179.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_96aa6b53-27b0-4378-a3c7-3d23f5feef6e.jpg?v=1788722679","url":"https:\/\/www.activepoolsupply.com\/products\/pressure-relief-valve","provider":"Active Pool Supply","version":"1.0","type":"link"}
