5 Pack Water Leak Detectors for Home, 100dB Water Sensor Alarm for Basement,Flood Leakage Detection Devices for Pipe/Drain/Sink/Faucet Drip Alert,Floor Flooding in Bathroom/Kitchen/Toilet/Laundry Room

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.

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.

Quality packaging and product construction. Easy to install included batteries. Instructions are adequate and easy to follow. The sensors sense even the smallest amount of water and the default alarm is LOUD although you can adjust the volume to one of 2 lower levels.

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.

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!

This is simple yet easy to use water leak detectors. It's small in size but with very loud alarm. I love that these use 2 AAA batteries rather than 9V battery like my old water leak detector, which was very difficult to install the battery. 2 AAA batteries are much easier to install and also readily available at home compared to 9V batteries. BTW, I was very glad to see that brand new batteries were also included with these detectors. These have 4 water sensors on the bottom and 1 sensor on top. I also love that it has large TEST button to test the unit and it can be used to turn off the alarm in the event when it goes off due to water detection. The best way to use these detectors is to place them on top of a paper towel so that if there's any water leak near by then it will get absorbed by the paper towel then immediately touch one of four sensors on the bottom to sound the alarm. I have placed these under the sinks and behind the toilet tanks so I will know immediately if there's any sort of water leak, which isn't something that I check often. Always test it before using it to confirm that it's working and I also appreciate that it has low battery alert so I don't have to second guess and check the batteries every few months. Highly recommend these water leak detectors. It will pay for itself by just alerting you with water leak once. Better safe than sorry... 5 out of 5 stars!

Changed the inlets to my black tank flush and city water last week. I apparently didn’t get the fixture tight enough, and when I started using the flush, water started leaking and set off the leak detectors. I was able to shut off the water fast enough to where there was very little water that leaked into the floor

A neighbor had a pipe leak and flooded half the house before awaking to a mess. When I moved in to my house, I discovered one AC's primary drain line was blocked, the water was going out the secondary line but the pan was dangerously close to overflowing. Earlier this year, one of my water heaters developed a leak, which I discovered when I noticed water dripping from the outside drain line. (My replacement water heater has a sensor that cuts off the water if a leak is detected). I considered the new whole house cutoff valve, that somehow learns water use patterns and shuts off when it thinks there is a leak - but there is no easy way to install one here. With all this in mind, I bought two packs, 10 total, and placed one in each water heater pan, AC pan, bathrooms and by the clothes washer - pretty much anywhere where a leak is likely. My daughter triggered one while cleaning a bathroom, so they do work. Hopefully I will never need to know how well they work, but it's a cheap warning system. (I told my neighbor about these and she ordered a set)

Ordered the 5 pack kit. Came as advertised. Complete with batteries. 4 Stars as 4 out of the 5 worked. The 5th water sensor would not work.

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