    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.

    First Alert water detector devise is cheap insurance. Senstive to even a slight amount of water. EZ to set up.

    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.

    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?

    • 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.

    • 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.

    • 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
