An immersion well is a sealed tube or socket that allows a temperature sensor or thermostat probe to be inserted into the water or fluid stream without direct contact with the water. This enables accurate temperature measurement within the heater system while keeping the sensing element protected and removable. The 72082 measures 3.5 inches in length and is built to match OEM fit and function for straightforward replacement service.\u003c\/p\u003e\n\u003cp\u003eThis immersion well is intended for pool and spa heating systems where the original well has corroded, cracked, or otherwise failed. It is installed within the heater body at the water inlet or outlet port, depending on the specific heater configuration. Pool and spa service technicians performing heater diagnostics or sensor replacements will typically encounter this component when troubleshooting inaccurate temperature readings or sensor failures. It is suited for residential pool heater applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOEM-style replacement immersion well for Pentair pool and spa heaters\u003c\/li\u003e\n  \u003cli\u003e3.5-inch length for correct probe depth and fitment\u003c\/li\u003e\n  \u003cli\u003eSealed design isolates temperature sensor from direct water contact\u003c\/li\u003e\n  \u003cli\u003eAllows sensor removal and replacement without draining the system\u003c\/li\u003e\n  \u003cli\u003eDirect replacement for simplified servicing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement immersion well for Pentair pool and spa heaters requiring a 3.5-inch immersion well.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pool and spa service technician. Before servicing, shut off power to the heater at the breaker and allow the system to cool to a safe handling temperature. Ensure water flow to the heater is isolated before removing the existing well to prevent water discharge. Verify thread type and size before installation to confirm a leak-free seal, and use appropriate thread sealant as required by local codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.5 inches\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: PENTAIR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 72082\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PENTAIR","offers":[{"title":"Default Title","offer_id":68079367258418,"sku":"072082","price":16.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/baae45f8b70be2fba819e4476bb94ad4.webp?v=1793120255","url":"https:\/\/voomisupply.com\/products\/pentair-72082-immersion-well-3-5-inches-pool-heater","provider":"Voomi Supply","version":"1.0","type":"link"}
