Answer: 
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

Rated 4.5 out of 5 by 36 reviewers.
Rated 5.0 out of 5.0 by Water Defense, Leak alarm I have these in my condo and they have saved me more then once from having to replace my laminate floors. When I bought a second unit for a rental they were one of the first things I installed!! and will never be without. March 22, 2016
Rated 2.0 out of 5.0 by 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. January 13, 2016
Rated 5.0 out of 5.0 by I hope I never need it but...... After the washer overfilled, I found it inexpensive insurance to get this product. By testing it I am confident that it will alert me well before the kitchen fills with water. March 8, 2016
Rated 5.0 out of 5.0 by It works! We live full-time in an RV. Due to the nature of RVs bouncing up-and-down the road, you do on occasion have a water leak due to a fitting getting loose. Well last night we heard a series of loud beeps from the Honeywell water detector and sure enough one of the fittings came apart, the hose clamp slipped off the plastic fitting. I highly recommend this product. It works! March 1, 2016
Rated 5.0 out of 5.0 by Water Leak Alarm -- it really works! We needed an alarm to let us know when water was entering our house. Our first floor is partially submerged under the ground up to our windows. This particular room has had 2 floods due to our landscape system leaking or breaking. After renovating the bottom floor with new carpet & pad, just a mere heavy spot of rain caused the alarm to go off. Luckily, the alarm goes on and STAYS on. It is battery operated, easy to install, and will save our downstairs from flooding once we know it is getting wet a little. I felt the carpet when it first went off, it felt dry;but the sensor knew better. By the time it was seen to, it was damp by about 2 inches in the corner of the house. Amazing how sensitive the alarm was. We fixed the outside issue, January 19, 2016
Rated 5.0 out of 5.0 by No More Hidden Mold After having a "secret" leak under our water heater upstairs for over 5 years that no plumber could ever find and our ceiling dowstairs even caved in once we finally fixed the leak using a FLIR camera. To prevent future hidden leaks put one of these things by water heater and by washing machines to make sure we aren't caught off guard by hard to see slow leaks that cause mold to grow. Like a smoke detector but for water. So far so good! March 5, 2013
Rated 5.0 out of 5.0 by water detection Easy to install. Easy to understand. And with a regular phone cord, you can extend your distance from water area to detect to base unit. Easy test. January 5, 2016
Rated 5.0 out of 5.0 by Water Monitor This is a great item, entire wire will alert you if it gets wet.. December 9, 2015
