Zircon Leak Alert Electronic Water Leak Detector & Flood Sensor Alarm with 90dB Audio Dual Leak Alarms, 1 Pack,White

How do you give a review on an item that just sits on the floor next to the grey water drain in the basement. You hope to never have to see this gadget actually working since that means the basement drain is backing up.....again!!!! It does give us a bit of peace of mind being down there though. If the drain should back up I'm not sure if we would hear the alarm since our home is quite large and that drain is down in the basement next to the furnace. Hopefully we will never see this item actually doing what it's supposed to do.

Tested with water: Work great. Loud enough to make sure we know there's a problem!

I bought the 5 pack...one for under the kitchen sink...two under bathroom sinks..and two next to the washing machine. I put a paper towel underneath the sensor to increase the area of sensitivity...Very easy to setup,,,Reasonable price.Good for apartments or homes...Its loud ...it is about the same as a smoke alarm..I tested it out and it is very sensitive.They look well built and like i say very easy to setup

If you want a water alarm that just works without needing a smartphone, this is it. It’s basically a smoke detector for leaks. I bought these after seeing a neighbor deal with a major flood from a leaky guest sink that went unnoticed for hours (all night, sadly). I tested it with a damp paper towel and the noise is incredibly loud and clear. It’s a huge relief knowing that if a pipe starts dripping under my sink or behind the fridge, I’m going to hear about it immediately. Highly recommend for every homeowner.

Like it’s super loud alarm sound and uses x 9volt battery that last very long
