    I bought 2 of these after my basement window well filled with water during a rain storm and the water had no where to go so it came in to my basement! I learned that night that I had no drain system for my windows. I placed one under the window and one under my kitchen sink incase my dishwasher or sink ever leaked. Last night, the alarm went off after we had all gone to bed when the counter mechanism from the disposal was clogged and the water from the dishwasher started to shoot out the top of it. We would have slept through the entire cycle and had a way bigger mess to clean up otherwise. The alarm was loud enough to wake me up and my husband heard it from down in the basement. I am now buying a few more of these for the bathroom sinks and my hot water heater which is next to my basement sink - 2 birds with 1 stone. We check the batteries 2X/year at the same time as our smoke/fire alarms.

    Hook up additional wires in parallel and cover multiple areas (close by) with one unit. I am covering two a/c air handlers in pans along with a humidifier.

    Seems to work well. We pruchased this item because of a recent hot water tank leak. Hope to never have a use for it. But we tested it out and it really worked well. Was very loud. Good name and we trust First Alert for our smoke alarms so I will put my trust in this for a water leak.

    This appears to be a good unit. After installing the battery I tested the unit on a plate of water. It went off and is loud. Removing the unit from the water was sensed in less than a second and the siren went off. I've placed it next to our water heater in the basement, however you can slide off the base and place the case itself up to six feet from the sensor. This is likely because the case itself isn't waterproof.

    Sounds like a great idea. I hope I never get to see it work. That would mean my slopsink overflowed. I have the wasing machine emptying into slopsink in the basement. We can hear the siren from upstairs.

    Does it run on either/or battery or electric or do you need both? Also, do you place it on the water heater or the floor around the water heater?

    • A. It is battery operated only. Under my hot water heater is a tray that is required by code. I used the "remote" feature and put the sensor in the bottom of the tray and mounted the alarm about eye level. It makes it easier to change batteries once a year. If you do not have the tray, you can mount the sensor on the floor under the hot water heater. I have 3 of these and they work great.

    • A. It is battery, 9 Volt, operated. You place the sensor contact down on the floor where it will get wet. I placed mine in a the pan that the water heater is in. The pan is metal so I had to put down some tape to keep the aluminum pan from shorting the sensor contacts.

    • A. 9V battery included. It goes on the floor where the leak would be. The sensors also pull put on about 6' of wire so you can put the alarm part in easy reach or where it can be heard easily
