Review on GE Personal Security Water Leak Alarm, Efficient Water Leak Detection for Bathroom, Laundry Room, Basement, Garage, and Beyond, 45411 by Philip Anderson

I love this little water detector! It has a very loud alarm, easy to hear on the next floor. You can just flip the switch to stop the noise, dry the contacts, and then turn it back on. I have other non-switch sensors that just keep roaring while I desperately try to dry them out to clog them, so this is much better. Checking the battery is very easy - just press the test button and the LED will turn bright red (no noise). substitute. The cable is about 10 inches long, so the main unit can be attached to a flat surface with the peel-off adhesive pad on the back and the sensor placed where needed. Our sensor has been submerged in water many times without damage, but the main part must remain dry. The only potential downside is that the sensor contacts don't lay flat, so you need careful positioning to detect small amounts of water on the surface (e.g. a slow leak under a sink). , very small and hard to see, so sometimes I accidentally turn it off. All in all a very good water detector at a great price!
