5 Pack Water Leak Detectors for Home, 100dB Water Sensor Alarm Black

These things are great! They are simple to use and function just as advertised. We had a sneaky leak under or kitchen sink. By arranging several of these on paper towels in the areas that were getting wet, we were able to find it and fix it. We then re-used them when we had a new dishwasher installed. They picked up a leak from the air gap that would otherwise have just dripped every time we ran the unit until we finally figured out there was a leak way at the back of the cabinet. Useful item. I'll be hanging onto them.

These leak detectors appear to work well. I placed them inside plastic pans under the drain pipes. I have 4 convectors that occasionally have leaks and one of them had a hairline crack in one of the trays which resulted in a slow drip. The detector sounded the alarm and I was able to catch the leak when there was a tiny amount of water in the plastic pan underneath. Had I not had the these, I may not have noticed the leak until I had a puddle or a flood. These are very easy to install and set. They have a volume setting too but even at the lowest setting, they're loud especially because I'm in a one level apartment. I recommended them to others who are also satisfied with the extra protection. Note that this model does NOT connect to your phone for alerts so if you need that option, you'd need to spend more money for a different model.

What I like best about these water detectors is they're very small and inconspicuous but extremely loud. I've been giving them away to my customers as I'm a plumber on things that we install in the basement and they saved us quite a few times from problems. Strongly recommend

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)

Very simple, but loud water alarms. The batteries are easy to install (2 AAAs). With multiple volumes for the alarms, they’re customizable. According to the instructions, you can also pair it with a “hub” to make the alarms “smart.” We didn’t purchase that additional device because I prefer simplicity. One downside is that the low power alert only occurs once and it is a short three-chirp alert (according to the instructions). So, we will need to be sure to check the devices every few months to make sure the batteries work. Ideally, these would chirp once every hour if the batteries are low. Otherwise, I’m happy with the simplicity, volume and size.

Very simple and cheap and very effective

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!

These are a great addition to keep on hand. They are SUPER loud and do their job accurately. I am grateful for the creator of these sensors as they really give great piece of mind. It does take batteries, but we've had ours for nearly 5 months and they are still going strong.

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.
