Water Sensor Alarm, Smart Water Leak Detector for Home & Basements | Made in The USA | Automatic Flood Detectors and Water Alarm, Pure Water Capable (WaterWatcher)

Compact sensor, not only alerts with 85 db alarm but also shuts off my dehumifier. I use a dehumidifer in the attic above my clothes closet (yes you can guess my problem). The dehumidifer did its duty, overflowed and ran down from the unfinished attic into my closet. 7 suits, numerous shirts, some Sheetrock damaged and corner tape required fixing. Found this alarm/shut off switch on Amazon. Am working right now to test a catch basin that houses the dehumidifier so if an overflow occurs it sonically notifies us while turning off the dehumidifier. So far all the “mock-ups” have worked, water in the catch basin sets off the alarm as well as turns off the dehumidifer long before there is enough water to cause damage. The alarm sets off at 0.2 inches of water in a 5 inch deep catch basin. Plenty of leeway. Easy to install, connects to a single electric receptical. Pretty loud alarm, don’t know if I really need that because of the automatic shutoff.

I recently repaired my washing machine and had little confidence about how well the repair would hold up, so I wanted an alarm to let me know if there were any leaks. This device does it all: 1. It has a sensor you place on the ground that detects water. It needs to be on a flat surface. It will detect water if the entire surface area below the sensor is wet, but it doesn't have to be a lot of water. Placing the sensor in a pan and dumping a cup of water in was enough to set the alarm off, so it is sensitive but won't falsely trigger. Think of it as a "puddle detector". Note if there is water near the sensor, but not under it, it won't trigger. So place it where you think water will most likely pool up. 2. It will sound an alarm that is loud, but not "wake the neighbors" loud until you push a button on the side to cancel the alarm. 3. It also TURNS OFF THE POWER to the device plugged into it! So for a washing machine where the water valve solenoids have to be energized to let water flow, they will get shut off automatically and the water will stop. That's exactly what I wanted! I think the cable from the main unit to the sensor is a little flimsy but once you set this thing up you'll probably never touch it again, so it's fine. I don't know if the power outlet on it is UL compliant, but if you are concerned about that you can still use this detector with nothing plugged into the outlet. In that case it will sound the alarm but won't turn anything off. I have a lot more confidence running the washing machine when I am elsewhere in the house knowing this alarm is monitoring the water situation. Highly recommended!

First, this does exactly what I need it to do. My washing machine drains into a tub that then needs to pump up a few feet to the sewer outlet pipe. As such I use a fine screen lint filter in the tub to avoid anything getting trapped in the pump. If this screen clogs up early in a load of laundry then during the final rinse and spin the tub could overflow. I've already had to mop up the basement a few times for this reason. This is the only product I have found that can sense for this spilled water and shut off power to the washer so it stops pumping out to the tub. In my tests it does exactly that. A bit pricey in my opinion for what it does, but if it saves me from needing anything more than a simple towel to clean up a tub overflow then I'll take it. There are some cons which I can live with. These have already been cited in other reviews: the smooth teardrop shape that can be difficult to grasp, the bulky size, the question of since when powered the relay is always on (this does allow for it to fail safe) will that reduce the life of the relay, and the need to remove power in order to reset the unit. As was noted in Roland Petit's answer to the question about shutting off or silencing the alarm, someone with a little electronics skill can bodge together a "reset" switch. Roland describes putting a switch on the transformer which I'm not a fan of as then you are dealing with a mod on the AC side of the circuit, something riskier than is necessary. I opened my unit to inspect it and found the logic us using an Atmel ATTINY44A microcontroller chip. Pin 4 of this chip is a reset that if brought low (grounded) will reset the chip. Conveniently there is a pinheader socket right nearby and two of the through holes are for reset and ground, conveniently both right next to each other. This is probably used for QA testing at the manufacturing plant. Wiring a momentary switch between these easily accessible solder points will provide you a much safer way to reset the unit, providing your mounting of the switch is well spaced away from the AC components. I've already done a workbench test of this and confirmed easy reset of the unit with these contact points. If I find a momentary switch that I feel I can mount acceptably then I will likely install that mod at that time. This unit has a 5-year warranty and it is minimal effort for me to unplug to reset, so I'm not in any rush to add this mod. THIS MOD SHOULD ONLY BE DONE BY PEOPLE WITH REASONABLE ELECTRONICS SKILL! FAILURE TO INSTALL PROPERLY COULD RESULT IN INJURY OR DEATH! NO QUESTION THAT THIS MOD WILL VOID YOUR WARRANTY! It is disappointing that for the price STAK Enterprises didn't have a reset switch already included as a part of the design. Another con that I found when I opened it up is that there didn't seem to be any strain relief in the main unit beyond the flex boot on the wire going to the sense puck. A good yank of the wire could pull it off the mainboard. Given the ample length of cable provided for the puck this probably isn't much of a worry, but while I had it open I still put a knot in the wire inside the housing that will take the stress if the wire gets pulled. One final note to keep in mind with the puck is that the two post contacts closest to where the wire enters the puck are the sense posts. The post that is opposite where the wire enters is just for making a 3rd leg to level the puck. I doubt it will really matter for anyone but if for some reason you want to sense for water directionally then have it facing with the exiting wire pointing towards the direction that you want detected first.

This device works excellent. I put this in a water tray to keep an eye out on a dehumidifier I put in my basement. I have a pump that pumps out the water from the condensation and if the pump goes bad, then it will turn off the dehumidifier. Excellent product.

This device is fantastic and performed excellently in my somewhat unique circumstances. When I bought my house, the sump drain was poorly configured with flexible tubing that was likely to fail and could potentially spray water all over the basement when it did, so I connected the sump to this device, ensuring that if it were to fail, the sump would just turn off.

This device works just as it was intendent. Like the added reset/mute button. I have installed on a 3/4 HP water pump. It gives me peace of mind knowing my basement won't flood if a pipe bursts or a connection fails.

If you have a problem with septic and your washing machine ect is running then this item will save you a big mess by shutting down the item you plugged into it also the alarm is quite loud.

Does what it's supposed to do. We had a sewer backup because our backwater valve was closed and the washing machine started it's drain cycle. Installed the sensor in our basement bathroom shower (our lowest point which is the first place water will come up) and ran the device to our laundry room. Tested it by starting the washing machine and pouring a glass of water by the sensor. Stopped the washing machine instantly! Wonderful device.
