Put leak sensors wherever water lives behind a door or under a cabinet: the water heater, the washer and every sink come first. Most water damage doesn't start with a burst pipe. It starts with a slow drip nobody sees for days.
The 8 spots, in order
- Water heater. Tanks usually fail with a slow drip from the bottom, not a burst. Set the sensor in the drain pan or on the floor beside the tank.
- Washing machine. Supply hoses crack with age. Put the sensor on the floor behind the washer, near the hose valves.
- Kitchen sink. Supply lines and the garbage disposal both leak. Place the sensor at the back of the cabinet floor.
- AC air handler or furnace closet. When the condensate drain clogs, the pan overflows into the closet or the ceiling below. Put a sensor in or beside the pan.
- Bathroom sinks and toilets. Under each vanity and behind each toilet, where the supply line connects.
- Dishwasher. Slide a sensor under the front kick plate if it fits, or in the sink cabinet next to it.
- Refrigerator ice-maker line. The thin plastic line behind the fridge is a common slow leak.
- Lowest spot in a basement or garage. Water collects at the low point first, and so should your sensor.
How many do you need?
Three covers the big risks: water heater, washer and kitchen sink. That's what our Starter Kit includes, with the hub. Add more as you go room by room.
Before you travel
- Test each sensor: a few drops of water should trigger the alert on your phone.
- Turn on notifications for the app.
- Leave the heat on in a freeze and the cooling on in humid months; never shut the system all the way off.
- Know where your main water shut-off is, and tell whoever is checking on the house.
