by 9-volt battery. I plan to change it out twice a year when Daylight Savings Time switches on and off. Just like my battery switching of our home alarms.

Answer: 
12 Volt battery. Even though we have had no leaks to really test it, I know when we first installed it, it was VERY sensitive and has a decent sounding alarm.

Answer: 
The manual says it does - by chirping periodically like a fire alarm. I've not had mine long enough for a battery to go bad so can't verify from experience.

Answer: 
Just installed mine & all we have in SC is humidity. I have the end of the line "alarm" detector positioned at the relief value in the pan so it goes off asap. My storage room is built into my house, have to go outside to walk in it. When I tested it, the end had to go into the water for it to go off. Just the end getting damp didn't do anything. I'm not an expert but I say no

Our hot water tank leaked in the middle of the night and we were lucky to shut it off without any damage to our homes or the condos below. This unit probably saved us from a very expensive insurance claim. My only complaint is that it could be louder. I will now be looking for one that can contact me remotely if there is a leak when I'm not home. Money well spent!

Rated 5 out of 5 by from Superb product that exceeded expectations. Rarely do you realize a need for something and then find it exactly like you envisioned. This is one of those needs for me that was exactly what I was looking for. And it came from my favorite store, Home Depot.

Rated 4 out of 5 by from Water heater leak alarm It installed easily, appeared to be well designed for the purpose but until there is a leak, it's functionality cannot be determined.

Rated 5 out of 5 by from Inexpensive insurance! Using on a water heater. Works exactly as advertised and is sensitive to even a very small amount of water. Great value.

Rated 2 out of 5 by from Bad quality I purchased 5 of RWD41 in late 2014. Within 6 months one of the units started chirping. I switched out the sensor cable and it stopped so I contacted Honeywell for a replacement sensor cable. They gave me a terrible time but eventually sent me a replacement. The 1 year limited warranty period expired about 4 months ago and another sensor cable went bad. These units cost over $20 each and the sensor cables don't seem to last more than a year or so. A replacement sensor cable is almost as much as a new RWD41. The quality of these sensors are terrible. Save your money and buy something that is more reliable.

Rated 4 out of 5 by from Almost perfect After 3 floods, shocked to come across this. It's a must as my water heater is in the storage room that's part of my house & backs up to my living room & laundry/kitchen. Last flood, 2 years ago raised insurance $500. Never again I pray. So easy to put up, only 4 stars because it's not loud enough. It's at one end of the house when I stay in the middle w/the tv going. I'll most likely get 2 more to add to it. It would get 10 stars if it could be programed into a cell phone. If no one is home to hear it, it's of no use. Unless you get home before the flood is too bad. They need to make it larger, to hold several batteries, whatever will make it a real ALARM but I'm grateful to have it. I'm always home & water heaters aren't made like they used to be. If I only had a garage for the water heater. I recommend it, you may be home when it bursts. If you house is like mine, get 3 & don't forget to change the batteries
