5 Pack Water Leak Detector, Adjustable 0-100 dB Loudly Wet Moisture Floor Water Alarm Leak Sensor, Sink Overflow Pipe Drip Alter for Home/Kitchen/Basement/Bathroom (Battery Included)

It arrived early. The batteries are included. Easy to use and you can test fire the alarm. The alarm is loud enough to hear in your house. Easy to install under the kitchen for leak detection. I bought one for each bathroom and laundry sink and washing machine. I would recommend and buy again if needed. Excellent price for safety.

Tested one and very responsive. Recommend, Great.. Brought for my RV.

We had our whole house repiped last week. Last year we had a huge water leak in the wall and had to have the entire kitchen replaced. We have severe plumbing trauma and we are terrified of water leaks- As a result I bought these handy little guys. Maybe I thought it into existence but the morning after we put them out (and used our washing machine for the first time) the alarm went off, loud. I knew immediately what it was and we came to find our entire laundry area flooded because the plumbers forgot to hook up the drain line from the washing machine. Had I not had one of these little guys my machine would have dumped countless more gallons of water in the rinse cycle 🫠. All this to say, it works, buy it and put it under every water hookup in the house.

These sensors are amazing! We had just finished having our kitchen and bathrooms remodeled and decided to purchase these to place under all our sinks to avoid any possible water damage or issues. Well low and behold the sensor in hall bath started blasting the day after install. It was discovered the plumber had not completely secured our faucet and a very small amount of water was detected. This sensor stopped any possible damage to our new cabinets. The alarm is super loud and so sensitive to even the smallest amount of water. I highly recommend these!

These leak detectors will work well for our use, but the instructions are a bit confusing and do not seem to match the product exactly. The manual refers to an indicator light and certain design features that are hard to see on the actual unit. When I tested them, I could faintly see the light come on, but it was not always very visible. The alarm/test function worked, so I feel comfortable using them under sinks and near appliances. Overall, they seem like a useful, inexpensive product, but the instructions could definitely be clearer.
