{"title":"Flo by Moen Smart Water Shutoff \u0026 Leak Detectors","description":"\u003cp\u003eFlo by Moen puts leak detection and automatic shut-off in one body plumbed into the main, plus battery puck detectors for the fixtures the main valve cannot see. Everything on this page is stocked and ships from our Seattle warehouse.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSmart Water Shutoff valves\u003c\/strong\u003e install on the main downstream of the service shutoff. The unit monitors flow, pressure and temperature, runs a nightly pressure test on the plumbing, and closes the supply on its own when it reads a leak. Size the valve to the pipe you are cutting into, not to a fixture branch: a 1 in. main needs the 1 in. unit or the whole house loses pressure through the device. We stock 0.75 in. (900-001), 1 in. (900-006) and 1.25 in. (900-002).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSmart Water Detectors\u003c\/strong\u003e are battery pucks that watch one spot and report to the same app as the valve. Put one in a water heater pan, under a sink base, behind a laundry box or at a sump. They sense water, temperature and humidity, so they warn before a pipe freezes rather than after it bursts. Sold singly (920-004) or in a three-pack (920-005) for a house with several risk points.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCable and accessories.\u003c\/strong\u003e The 6 ft Smart Leak Detect sensing cable (920-006) extends a puck along a run of pipe or the length of a pan, where a single point would miss the water. The 25 ft extension cable (920-003) reaches an outlet further from the main than the stock lead allows.\u003c\/p\u003e\n\u003cp\u003ePairing note: the shutoff valve and the detectors work independently, but on the same account the detectors can trigger the valve to close. A whole-house valve without detectors still catches a leak downstream of itself by flow signature; detectors without a valve raise the alarm but close nothing.\u003c\/p\u003e\n\u003cp\u003eRelated: \u003ca href=\"\/collections\/potable-water-leak-detection\"\u003eWater leak detectors and shut-off valves\u003c\/a\u003e · \u003ca href=\"\/collections\/floodstop\"\u003eFloodStop appliance kits\u003c\/a\u003e · \u003ca href=\"\/collections\/moen\"\u003eAll Moen\u003c\/a\u003e · \u003ca href=\"\/pages\/water-leak-detection-guide\"\u003eWater leak detection guide\u003c\/a\u003e\u003c\/p\u003e","products":[{"product_id":"flo-by-moen-0-75-in-water-leak-detector-with-automatic-water-shut-off-valve","title":"Moen 900-001 Flo by Moen 0.75 in.
