WasherWatcher Laundry Tub Overflow Protector - Water Leak Shut Off Detectors w/ LED Indicator, Alarm, Water Sensor, & More - Easy to Install Washing Machine Leak Detector for Any Drain System

I tested it before installing and it tripped. It also has an alarm that goes off letting you know. Hopefully, no more water issues in the wash room.

Ever forget to unplug the laundry tub drain before starting the next load of laundry?? Maybe the sound of an overflowing laundry sink is bothersome?? Well having been the victim of my own forgetfulness, I purchase this little device, and now, I have no more worries of flooding my garage shop because the sink drain is plugged.The alarm is loud enough to hear, but not so loud as to raise the dead, and - it does as advertised and shuts off the washing machine as soon as it's activated. Price for the peace of mind is totally worth it.

After a couple of basement water disasters of my own making, I finally got smart and ordered one of these. I've owned it for quite a while now, but recently managed to drop a sock in the laundry tub when loading clothes into the washing machine. Needless to say, the sock plugged the drain, so when the water was draining from the machine, it backed up to this device, which did its job and shut off the washer and put out its characteristic beeping sound. It took me a minute to realize what it was, but I was so thankful that one water disaster was averted, thanks to this awesome little device. It worked perfectly as designed.

It was easy to install and works great, but why doesn't it have a reset button. You have to unplug it to reset it

Great for turning off the washer if your sump pump fails. The original unit (that was several years old ) was taken out by a massive power surge.

I don’t normally write reviews, but this Washer Watcher has just paid for itself. I came Home from work the other day and entered my house through our Utility Room, once inside I heard a beeping that I didn’t recognize so I asked my Wife to help me. We found that the beeping was from the Washer Watcher, our Utility Room Sink was filled with soapy water right to the sensor. Well the sink was backed up and not a drop went on the floor because the Washer Watcher shut off the power to the Washing Machine and stopped the water from entering the sink. When I researched these protective devices most required redoing the plumbing, the Washer Watcher takes 5 minutes to install if that long and is at least $100 cheaper than the more sophisticated devices. This was money well spent.

I formerly purchased this product from Menards for around $25, but the unit now only sells for nearly 3 times this price. Since there is no other product on the market like this one, I accepted this. Now, I have found that they have changed the product for the worse. After first detecting water in the laundry tub, the sensor locks the unit into the alarm mode, stopping the washing machine, flashing the red light, and sounding the very loud, annoying alarm non-stop until the entire unit is unplugged (even after the water has run down the drain, and is no longer being detected by the sensor). The product used to automatically restart once the sensor no longer detected water in the laundry tub (once the water had gone down the drain). I have cats in the house, and do not want to torture them with the very loud sound of the alarm any longer than I have to, so I'm now much more restricted in when I can and cannot run the washing machine (I have to be home, and able to hear the alarm). Here is what the instruction sheet that came with the product states:"When the sensor detects water the output is de-energized, the LED will turn red and the alarm will sound. When it is triggered the WasherWatcher will latch in the de-energized state and needs to be reset to enable the output to turn back on. This is accomplished by unplugging the switch from the outlet, waiting a few moments, and re-plugging it back in."Very disappointing.

The old one lasted 10 years. I hope for the money they charge for this one it better last 20 years.
