Product review: DB-Tech DB-WAW400 Wireless Water Overflow And Leak Detector

DB-Techi wireless water alarm consists of two units. The smaller unit is the water alarm transmitter (its size is 2.25" x 3.5" x 1") and the larger unit is remotely controlled receiver (its size is 5" x 4" x 1.25"). The transmitter unit has a water sensor probe which is attached by 82" cord to the unit. It also has a retractable antenna to communicate with the receiver unit. Both units have keyhole hangers and come with mounting hardware and two hole templates to make mounting easier. If you have an unfinished basement and can't easily mount the unit on the wall, the cord is long enough to place the unit on top of the water heater while the sensor is at the floor level.

The transmitter unit operates on one 9V battery (not included), and the receiver operates on three C batteries (not included).

I am attaching a video which shows the water alarm operation. The water alarm worked smoothly, however it took some experimenting to figure out when the alarm generates sounds (the manual is not clear).

✔ The transmitter and the receiver both generate sounds. Each one generates a different type of alarm and on a different schedule.

✔ The receiver generates a beep-beep-beep sound for a few seconds every 10 minutes. The receiver can be re-programmed to generate another beep sound, but I was satisfied with the default sound.

✔ The transmitter generates a twirling sound for longer periods of time with shorter breaks.

✔ Each unit has a switch that allows one to turn off the sound manually, which is a good thing because the sound is loud and annoying. Loud and annoying is a good thing for an alarm, but it is also good to be able to turn it off once you know there is a problem.

✔ The video shows that the alarm is very sensitive, it needs very little water to start making noise.

To summarize:
1. Very sensitive, alarm is set off with a small amount of water
2. Reliable, alarm went off in every test I tried
3. The alarm itself is fairly loud and the receiver unit can be mounted in a different location in the house, where it can be heard even better.
4. Mounting might require some creativity if you have an unfinished basement or if the water heater is not near a wall.

I received a sample unit from manufacture to share my experience with the alarm (be they positive or negative) the with the potential future buyers. I addressed pluses and minuses of the unit, and overall recommend it. This inexpensive device can save you a lot of money by alerting you about an unexpected flood before significant water damage occurs.
