{"title":"Water Heater Shut-Off Valves \u0026 Leak Protection","description":"\u003cp\u003eA water heater is the appliance most likely to flood a house, and the one most often installed where nobody looks. These are automatic shut-off valves that sit on the cold supply to the heater and close it when a sensor finds water on the floor or in the pan. All ship from our Seattle warehouse.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTaco LEAKBREAKER\u003c\/strong\u003e is a control unit with a motorized 3\/4 in. NPT ball valve, actuator and floor sensor, built specifically for a water heater. It is resettable and testable after a trip, so a nuisance alarm does not mean a service call, and it signals with a two-color LED and an audible alarm. The LB-075-H-1LF ships with one sensor, the LB-075-H-2LF with two, for a heater with both a pan and a nearby floor drain. The eLink version (LBW-075-H-2LF) adds WiFi and reports status and trips to your phone.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFloodStop 20001\u003c\/strong\u003e is the same idea at a lower price point: a 3\/4 in. NPT MIP x FIP valve with control unit and sensor. The MIP x FIP body threads inline with the existing supply nipple, so the install is a union break rather than a pipe cut.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSizing and placement.\u003c\/strong\u003e All four are 3\/4 in. NPT, which is the supply on effectively every residential tank heater. Put the valve on the cold inlet, upstream of the heater, and the sensor at the low point of the pan or the floor. A shut-off on the heater protects the heater only — if you want the whole house covered, a main-line valve is the right device.\u003c\/p\u003e\n\u003cp\u003eRelated: \u003ca href=\"\/collections\/potable-water-leak-detection\"\u003eAll water leak detectors and shut-off valves\u003c\/a\u003e · \u003ca href=\"\/collections\/flo-by-moen\"\u003eFlo by Moen whole-house shutoff\u003c\/a\u003e · \u003ca href=\"\/collections\/floodstop\"\u003eFloodStop appliance kits\u003c\/a\u003e · \u003ca href=\"\/collections\/water-heating\"\u003eWater heaters\u003c\/a\u003e\u003c\/p\u003e","products":[{"product_id":"floodstop-water-heater-kit-with-3-4-npt-mip-x-fip-valve","title":"FloodStop® 20001 Water Heater Kit with 3\/4″ NPT MIP x FIP Valve","description":"\u003cp\u003eThe FloodStop® Water Heater Kit with 3\/4″ NPT MIP x FIP Valve by FloodStop is part of our leak detection valves selection.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e FloodStop\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part #:\u003c\/strong\u003e 20001\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Leak Detection Valves\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FloodStop","offers":[{"title":"Default Title","offer_id":44350697668711,"sku":"FLOS-FS3\/4NPT","price":270.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0651\/2253\/3479\/files\/20001.jpg?v=1785805925"},{"product_id":"leakbreaker-water-heater-shut-off-valve-w-control-and-sensor-3-4-npt","title":"Taco Comfort Solutions LEAKBREAKER -
