We had an issue with our drain line from the washer backing up. It made a huge mess. I didn't hear the water pooring out of the drain pipe onto our floor untill it came cascading through the ceiling to the first floor. I installed a 9V battery. Tested the sensor under the faucet. Works well and is loud. Now I can feel better knowing that if the issue occurs again. I will get a warning in time to cut the washer off. Very inexpensive. 👍

A simple product for a reasonable price, works as advertised. If you are home most of the time, this should give u adequate warnings, if not home often… get a WiFi hub with sensors to text/alert you remotely.

This alarm works great. Very simple to use and very loud. Alarm is in basement, and you can hear it upstairs at the opposite end of the house. Extremely easy to reset.

Works well. Has a very loud alarm when wet. It's a good cheap product. Only bad part is that the wires are brittle and can fray easily. Had to buy another set to replace old set. Lasted about 2 yrs.
