Use the Basement Watchdog Battery-Operated Water Alarm to detect leaks before costly water damage occurs. This alarm can detect as little as 1/32 in. of water and produces a loud 110 dB alarm that can be heard throughout the house to provide an effective early warning system. The water alarm can be placed directly on floors or mounted for installation in a variety of locations: in a sump pit, near water heaters, refrigerators or dishwashers, next to washing machines, under sinks, close to air conditioner drain tubes or wherever there is a risk of water damage. The sensor with 6 ft. of wire offers installation versatility and can accommodate the addition of more than 100 ft. of wire. The water alarm operates using a single 9V alkaline battery and has a battery-saver feature that only uses energy when the alarm is sounding.

  • Detects as little as 1/32 in. of water to offer an effective early warning system
  • Solid-state circuitry is extremely sensitive and reliable
  • Loud 110 dB alarm can be heard throughout the house
  • Sensor has a 6 ft. wire so it can be extended into a sump pit, or mounted on a wall
  • Accommodates the addition of more than 100 ft. of wire (additional 24 gauge wire not included)
  • Battery will last approximately 2-4 years or as long as stated on the battery packaging

Rated 4.6 out of 5 by 105 reviewers.
Rated 5 out of 5 by Every home should have at least one of these! I wish I knew about this product earlier. The drain on our air conditioner clogged and flooded our hallway and dining room ruining the wood floors. I thought then that I wished there was some type of device that would warn of a water leak. Then one day I happened across this product while looking for something else in the plumbing isle at Home Depot. I bought it and tested it out at home and it works great. It has a loud, high pitched alarm that sounds when water comes into contact with the two metal spots on the bottom. I set it on the floor behind the A/C filter (CLICK ON PHOTO BELOW). I plan on getting another to put near the water heater. It was only $10 and could potentially save me thousands of dollars in water damage. Highly recommended!! December 10, 2014
Rated 5 out of 5 by Cheap Insurance for Basement and Garage Flooding After having the horror of a floor drain backing up in the basement, I wasn't about to take another chance in not knowing when water was coming up onto the floor. I bought this water alarm after seeing that I could install the sensor wherever I wanted and have the alarm itself high and dry, closer to where we'd hear it easily. It can detect water as shallow as 1/32nd of an inch deep. Giving you plenty of time to take action before it's a full on flood. It requires a 9V battery (not included) to operate. The manual says it can last up to five years on one battery, since it only turns on when the sensor gets wet. You can place the alarm right on the floor, or you can detach the sensor and place the alarm up to six feet away with the included wire. You may extend the wire up to 100 feet if you need to. This alarm would also work great to detect leaks from things like spring thaw through the foundation, sump pump failure, hot tub leaks or even an aquarium leak. Given that it has a five year warranty and it's so inexpensive, there is no reason not to have at least one of these in your home. It's far less expensive than an insurance claim or paying to repair and clean up water damage. March 9, 2014
Rated 5 out of 5 by Excellent sensitivity, easy to install, great features, highly recommend it. We've had a couple minor water related problems over the years, mainly caused by poor reliability of available sump pumps and their switches. So after the most recent episode, I replaced the sump pump with most durable I could find and built my own switch to control it. For extra piece of mind, I purchased 2 Basement Watchdog Battery Operated Water Alarms. I like the removable sensor feature that allows the homeowner to mount the alarm on the wall and put the sensor 6 feet away on the floor. You can also splice in extra wire if needed. I spliced in a second sensor, made from 2 stainless steel screws and nuts, that hangs down into the sump on a couple small pieces of PVC pipe about an inch above the waterline where the switch turns the pump on. If the pump fails for any reason and the water ever reaches the screws, the alarm will sound. The actual splice is 2 more stainless screws and nuts, mounted on a piece of plastic that I set on the floor beside the sump. That forms a 3rd sensor for “free”. The second Watchdog Alarm unit that I bought I just put a battery in, wrote the date on the side, and set it on the floor near the water heater, just in case. While I was home last weekend, our electricity went off. I knew it was just a matter of time before the sump would fill without the pump running. Sure enough, within 5 minutes the alarm sounded just as advertised. These units are extremely easy to set up, just put a battery in, and put it sensor side down on the floor. I recommend writing the date on the side to remind you to change the battery after a year or two. Or you can extend the sensor with or without DIY modifications to fit your application. They are very sensitive, just touch the sensors to give yourself piece of mind that they are working. For the price, anyone with indoor plumbing should have a couple to alert you to water where it's not supposed to be. May 21, 2013
Rated 5 out of 5 by Keeping Fingers Crossed I gave it a 5 star rating in anticipation that its gonna do what it claims to do. If so, it will well be worth its cost. Wish i had know about it before my water heater went, maybe i wouldn't have had to spend $750 to clean up the mess. I've since bought two, one for water heater area and one by the washer/dryer.

Rated 5 out of 5 by Easy to use for piece of mind Put battery in, place it on the floor and don't have to worry about my sump flooding without the warning alarm. April 29, 2014
