The Resideo RWD42 Water Leak Alarm offers superior protection against leaks and water damage near potential trouble spots close to plumbing around the home or office. This patented 5 ft. cable solution extends the detection zone offered by traditional spot detectors by 3100%. Additional cables (sold separately) can be connected to extend the cable and increase water sensing area up to 240 ft. Water Sensing Cable detects water on entire length of cable. Place the cable in spots where you do not usually observe such as water heaters, sump pumps, under sinks, around toilets, behind washing machines and dishwashers. This is the only system that can run around the entire perimeter of a room or basement. The Resideo Water Leak Alarm also gives off a chirp sound when the battery is low. This detector can be placed flat on the floor or mounted on a surface, for wall mounting, use double-sided tape (included) to adhere to a dry surface. This unit works directly out of the box with no assembly required, simply add batteries and place in the desired location where you want to prevent water damage.
Easy to Install
The detector is powered by 2 AA batteries (not included). Do not mix old an new batteries. Do not mix rechargeable and alkaline batteries.

This leak alarm was so easy to install, a baby could have done it. So far so good. BUT I hope I never have to test it with a leak.

Liked the alarm, easy to use, good price. Think the alarm could be louder than it is though.

There is nothing better than this
This will go off if ANY moisture touches ANY part of the sensor cable. Other, inferior alarms have a long, plastic covered wire with the only part that senses water being a gizmo at the end. The wire could actually be submerged in water and there would still be no alarm if the box at the end isn't wet. Talk about a false sense of security. Imagine the damage that could occur under, say, a dishwasher, if a rivulet of water from a slow leak touches the wire but avoids the sensor on its stealthy journey into the apartment ceilings below. That won't happen with these alarms. Just make sure the fabric covered sensor cable is taped down flat with small pieces of tape along the whole length. You will have to provide better hold down clips than what are provided, however, because the provided ones have poor adhesive on them. Even a damp rag accidentally touching the cable will set off the alarm. To silence it you will have to unplug the cable for a few minutes until it dries out.

Resideo RWD42 Water Leak Alarm With Sensing Cable
I have had the Water Leak Alarm for at least three years since a neighbor had a flood that caused extensive damage to his ceiling. The Water Leak Alarm is easy to set up on your smart phone and easy to check when you're away from your home. Notifications are sent to your smart phone when the alarm senses a problem or gives you a warning. I've actually had a bathroom ‘very slow leak. I received notifications but didn't see water on the floor ?. But, when I passed my hand across the ‘Sensing Cable I felt it wet. This leak would have only gotten worst. I was able to make a minor repair and avoided what potentially could have been a real problem. I have four devices and have just added two more including the attic where the HVAC is. I plan to give my two sons three Water Leak Alarms each for their homes. I'm very happy with the product and I tell others my story.
