Water Leak Monitoring Sensor with Alarm 1 Pack - Leak Bug Electronic Water & Flood Leak Detector - Detects as Little as 1/32" of Water - Overflow Alert Sensor Beeps Loudly When Water is Detected

I've only had these leak bugs under my sinks for two months & they've already saved me 4 times! Worth it! The kids get excited when the leak bugs go off haha.

These things are really great for your basement day alert you if any water backs up

I had one of those already. Ordered 3 more one under the garbage disposal, basement water heater and under the dishwasher. Had it go off once when the disposal leaked and was able to fix before any damage happened!

I use this in shower of motorhome which has no alarm when gray tank is full! Works as hoped .

Have had this alarm since 2021. Not sure if we have ever changed batteries. It works VERY WELL. Today it went off under our bathroom sink, where there was only about half an ounce of water. Chirps 3 times, then stops for a few sevonds then chirps again (like a loud robin)......non-stop.

I've had the frog version for several years. They've saved me from a leaky basement many, many times up in Ohio. I just bought the lady bugs for my Florida home a few months ago. Well, the one under the kitchen sink started chirping a few days ago. It took me a minute to find the source of the chirp, but sure enough, it was the lady bug alerting me to a leak under the sink. I was able to stop the leak in seconds and before any damage at all was done. Even the next door neighbor heard her chirp! Granted our walls are paper thin and the houses are close together, but the chirp is loud enough!

I got this leak bug to protect under my sinks inside their cabinets, behind the refrigerator where the ice maker and water dispenser had already leaked causing water damage, and by a window that kept leaking until a fourth contractor actually found and fixed the problem.One evening, the leak bug under our kitchen sink went off. I slowly removed everything and there sat the leak bug in as little of water as possibly could be detected, imho, basically just drops. I had set the leak bug on a piece of paper towel. It soaked up enough drops of water and being the brand it is, known for continually being able to absorb water, the leak bug finally went off. I say "finally", but seriously, barely a leak.I checked all the hoses and pipes in the area and found nothing wet. I dried everything up and sat the lady bug up again upon a small piece of paper towel.A week later, she alarms us again and the same exact scenario was present, although this time some drops were even on the lady bug. I checked all pipes and hoses again, especially directly above the lady bug and found nothing. I accidentally hit a hose about midway up in its length and water fell onto the back of my hand. I traced the water source to be located to a coupling in the water intake hose to the sink.I explained all this to our plumber and he felt that this was easy enough for his side kick to check into. He arrived the next morning, first thing, but there was no water leaking to be found, not even in that coupling. He asked if I wanted it replaced anyway and I said, "sure, go ahead."A week later, the same thing! Lady bug was there to mock our lame attempt to fix the problem!This time, my plumber, not his side kick, showed up 2 hours after the lady bug's alarm went off. Same deal. Nothing was wet anywhere, but the coupling (the new coupling!) somehow still held water. Our plumber said the only way he could think of other than a faulty coupling is that the lower hose's plastic inner lining was beginning to crack. He replaced the lower hose and I put the lady bug back on her paper towel perch.She hasn't alarmed us since! Our plumber was so impressed that such a leak was caught so early! He also loves the idea that homeowners can prevent the costly damage due to plumbing failures. He asked me to send him a link to this product so he could recommend it to clients, especially those with tricky leaks like we had!I am against any compensation via discounts, coupons, or any other cost break for giving reviews. This review is my true experience.

These are a little pricy but they really work. I keep one under every sink and consider them all insurance against very costly repairs. I also keep one near my home water heater and AC/furnace. I also have them positioned near each of my aquariums. They are very easy to use, super sensitive (I just lick my fingers and touch each contact to test them), and very loud!
