Water Leak Alarm Detector Flooding Sensor Alert 110 Db Battery Operated -Fish Tank Sink Tube Water Heater Sump Pump Alarm Indoor

I set this up for my sump pump. Tested it on the kitchen sink first. It works for the slightest drop of water. Definitely can hear it from my basement. Only con I've found is that it only goes off for a minute. So if you miss that one minute, you don't know you're flooding

Works great, extremely loud considering its size.

I used this to sense possible water leaks behind my built-in fridge. It is an advantage to have a long sensor cable, so I placed it inside the drywall to the bottom. I also tested it before putting it in place and it sounds when touched to water.

I had the sensor in a catch bucket. Went downstairs and the bucket was full and overflowing. The alarm never went off. However, it did go off sitting in the trash can when I threw it out. Only use it in cases where it might be nice to know, because you cannot trust it to go off when you need to know.

Buyer beware. This alarm is innacurate and will wake you up out if a dead sleep for no reason. It doesnt work, flooded my carpet too many times by not alarming. Chucked it in the trash. Cannot be trusted

This is an inexpensive way to have an alarm in case the sump pump stops working. Arrived quickly. Works great. Hope I never have to use it but glad it is there just in case.

When water touched it when testing, the alarm went off. That’s why I bought it...so far it looks like it should prevent the basement flooding without my knowledge...hope is that it never has to go off!

Loud sound so it definitely makes you aware of water leaks. The batteries are easy to replaced. Overall, it's a great product.
