LeakFrog® LF002B Water Leak Alarms

These are just great! No two ways around it. I have had my basement saved twice by this device. The last time it went off and woke us up in the middle of the night that the hot water heater had failed and while I got to it quickly, it still had submerged the original LeakFrog from 5 years ago and shorted the board out, so I bought a pair of new ones and actually bought a total of six and gave the others away to employees as a holiday gift. Put this behind your washing machine, next to the water heater, and on the basement that gets some water from time to time so you can move the items up BEFORE they are all soaked.

This thing has saved me so many headaches. My basement had some water problems, but thankfully only on the unfinished part on bare concrete. However, if it was raining very heavily and the leak was undiscovered, it would have been possible for it to reach the finished, carpeted part of the basement. While we were working to fix the root of the problem, we got these LeakFrogs so we would know immediately when there was a problem and we could stop it before it got bad. Out of the box, these did not come with batteries. That was a bit disappointing because the listing said it did come with them, but Amazon credited my account the cost of a pack of batteries, so I was able to get batteries with no (real) issue. Once I got the batteries, I tried it out. Worked great, so I put it on the bare concrete where the water comes in and waited. Sure enough, that thing started beeping like crazy one night and I was able to prevent water damage. On multiple occasions this has saved time, money and lots of stress. Now, even though we've fixed the root of the water problem, we keep one in the basement and test it every so often, just because it was such a good little tool.

Was not as described. Stated as coming with 6 batteries. Came with NONE.

No brainer. Installed the battery and placed the leakFrogs at various spots - too easy. Last week the one in the attic went off, alerted me that there was a little water around the water heater.

I received my 2 leak frogs - and there were no batteries in the box. It wasn't a big deal - but I felt that if it stated "with batteries" then there should have been batteries in the box.

This was our second batch of "leak frog" we had purchased. They are constantly on guard and work perfectly. Saved our bacon several times.

Tested them in the sink with a small amount of water and they seem to work perfectly. I have them under my upstairs toilets.

I'm glad that my wife had talked me into getting a water alarm as a first line of defense after last year's storm season alerted us to some leaky windows. This water alarm woke us up at 3am one morning, which allowed us to catch the puddle that was forming beneath a window before it ruined our rug. After this experience we doubled down on our water alarms so that we might get a more advanced warning the next time a storm comes through town. Now we're confident enough to toss out a few ugly absorbent water "snakes" that were lining the floor beneath the windows, so we're good as long as someone is home to respond to the alarm.
