Use the Basement Watchdog Battery-Operated Water Alarm to detect leaks before costly water damage is caused. 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. A convenient battery-saver feature only uses energy when the alarm is sounding to offer a long battery life.

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.
Pros: Reliable, Easy to Install, Good Instructions
Well, my plumber was in my home and mentioned that he didn't see a "water alarm" in the basement. (3 weeks ago) He said for ten bucks I would be a fool not to have one. I bought one the next day, it sat around for a week until I put a 9v battery in, and then down to the basement it went. I put it by the sewer back flow opening, and BAM! this morning my wife calls me about the noise in the basement. Sewer backup! is was only wash water, but I don't go down there every day, and I would have had a basement full of poo. a massive cleanup was avoided,and we cleaned up with a paper towel or two. the plumber is there clearing the drain right now.
I bought one 10 years ago (I wrote the date on the battery) at Home Depot. Recently one evening while watching TV in the living room, I thought I heard a noise like a smoke detector coming from the basement. My wife who had been down there 30 minutes earlier told me I was hearing things. I opened the basement door and heard the noise. Walking down the steps in my stocking feet as soon as I stepped off the last step, I stepped into warm water on the carpet. I knew immediately what had happend and immediately turned off the main water valve. This $10 alarm saved me thousands! I'm going out tomorrow to buy a couple more!
Works well and easy to test with a little water or your hand. Since I was going to splice in some wire into the existing wire for a long run anyway, I wondered if I could add a "sensor". So I spliced in two more wires - 3 and 12 foot bell wire, wired in parallel - and then took two small pieces of wood and put screws in the blocks (spaced like the two contacts on the original sensor) and used them to secure the other ends of the wires. And it works ... if water hits either the original sensor or my two make shift ones the single base unit alarms. And now I've got coverage for an odd shaped space that includes a lift station and water heater for the cost of my time and the parts and pieces I keep in the shop.
We have water pipes that sometime leak therefore we have about 8 of these in our finished basement. They are very sensitive and detect moisture extremely well. Very loud alarm. Give us peace of mind having these to avert a major flood.
We have water problems in our basement whenever we get a lot of rain in a 24 hour period. This alarm is loud and reliable and has saved us many times by letting us know when there is water in our sump. It has given us time to take action in the cases where the sump was overwhelmed. Like it so much we bought one for a friend with similar problems. Only drawback is cord is not long enough to mount anywhere but next to sump. I soldered 70 feet of speaker wire to it and placed the unit upstairs so we get notice even when sleeping.
It's 5:00 AM. I hear the scream of an alarm. What is it? Fire? Gas? Break-in? Nope.... it's my water alarm I installed 2 years ago. All I did was install a lithium battery (for long life) and place it near the water heater. It is SO easy. If I didn't have this, I would have flooded the basement. I have since purchased another 7 units to place under my sinks, toilets, and refrigerator. It was loud enough to wake me up from 2 floors away, behind 3 separate closed doors, and with a fan running in my bedroom. My wife said I was silly to get this when I purchased it years ago. Needless to say... I now get to say "told ya so".
This product is something that you buy and forget about such as a smoke or carbon monoxide detector. It is there to do a job which is protecting your home but you don't want to ever hear the alarms go off! I bought the water alarm for that purpose, to protect my basement from flooding.
I've bought 2 of these. My basement flooded when I wasn't home the first time so I don't know if the alarm sounded. The second time my basement flooded, I was upstairs and should have heard the alarm. When I went down to the basement and found it was flooded, I found this box submerged in the water, the connectors were definitely wet and the alarm never sounded. The unit and battery were about 5 months old.
Pros: Easy to Install
Cons: no reliable

Review 12 for Battery-Operated Water Alarm
It didn't work after the sump pump failed
PostedAugust 14, 2013
Ease of installation
No, I do not recommend this product.
After my 5-week old sump pump failed (made by the same company) this alarm failed to do its job. Seems to be a trend with these guys. I had couple of inches of water (never mind 1/32") and no alarm. Stay away from this alarm and this company.
I live on the second floor of a condo with an 80 gallon water heater in the first floor garage which is an attached part of my unit. It is located in a closet with a closed door .If there was a leak I might not be aware of it for days. I was skeptical that a ten dollar item would operate as advertised. When I tested it with a small amount of water in my sink,it worked perfectly. I have advised two friends to get one . They did and are equally pleased.
Was worried about the hot water heaters leaking (they are in the attic). I didn't think the alarm would be loud enough to hear in the house, but I tested it and was wrong. This alarm is the loudest I could find from any manufacturer. Easy install - just stick in the 9V battery and set it in the water heater pan.
Bought this to put in the water heater pan so I would know if water was leaking from the water heater. I had positioned the pan in the wrong place and there wasn't enough room for the unit to sit beside the water heater. Bummer, till I read the directions. Slide out the sensors and set the unit itself on the top of the water heater. WOW, and you can add up to 100 ft of wire between the sensors and alarm. WOW. $10 is a very cheap insurance policy against water damage. Fantastic product for the price.
