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.

yes as soon as you remove the contacts or eliminate whatever is causing continuity the alarm stops. Its very simple as soon as something creates a circuit between the two silver contacts on base it starts.. remove it and it stops..

I read a review/hack online that if you are comfortable soldering and wiring, all you have to do us take the removable sensor off the bottom, tap into the wiring, extend however much you need to, and create a second set of contacts. Basically all it takes is two more contacts in the second location, that can complete the circuit if they get water on them. It won't be an OEM modification, but what I read Read More

On the other hand, as inexpensive as these are, your time is probably worth enough you could just buy a second unit for less than the value of your time to modify it. Read Less

Answer: 
The unit has an attached sensor which allows you to mount the unit and have a remote, wired, sensor. For example you can place the sensor in the back of a cabinete under a sink and mount the unit where you can access it easily. There are no controls. Battery in, unit on. Water under the sensors, loud noise. No water, shuts off.

Answer: 
Usually, humidity will not set off the Basement Watchdog Water Alarm. Both of the sensors need to be connected by at least 1/32" of water. If this much moisture were to build up, however, it would trip the alarm. Please contact us directly for more information at 800-991-0466 ext 3 for tech support M-F 9-5 CST.

Answer: 
It should not - there are two electrical contacts on the bottom, over an inch apart, and it requires liquid water to create a circuit between them to activate the alarm. However, if it sits on a floor that gets significant condensation, such as in a very damp basement, that might be enough to trigger it.

Rated 4.6 out of 5 by 164 reviewers.
Rated 4.0 out of 5.0 by Excellent fail safe for sump Super easy to install and used a zip tie to attach the sensor below the "flood" level to prevent any damages to home -- love the extension cable so you can place the box out of the flood zone to hear better. CHEAP!! March 29, 2016
Rated 5.0 out of 5.0 by This thing works! I'm sorry to report this thing works! Sorry, because we found out when it started squealing from the basement. Thought it was the smoke detector but quickly realized it was the alarm, alerting us that the main drain was backing up. It alerted almost instantly, allowed me to shut off the washer before it flooded stuff, and get the drain fixed before the backup caused real damage. Best $10 or so we've spent. I've added one under the kitchen sink, and behind the washing machine, as the other two most likely places to have a damaging leak and not know until it's too late. And installation consists of popping a battery into it, and setting it where the leaking water will puddle. Done. It'll take you longer to open the packaging than to set it in place. July 13, 2016
Rated 5.0 out of 5.0 by MUST HAVE This device just saved my wife and I thousands on potential flooding damage in our basement, we were notified in the middle of the night with plenty of time to react to water seeping in our basement from unusually high and fast amounts of rain. I will be buying another one for extra security as this product gets a 10 out 10 in my book August 16, 2016
Rated 5.0 out of 5.0 by Simple but very effective watchdog It doesn't get any simpler than this little device. It's meant to warn you if there is any water present in areas that you don't want it. It's basically a battery powered, very loud alarm that is triggered when water connects the two metal contacts on the bottom. Water conducts electricity so it acts like a switch to turn on the alarm. When you lift the contacts out of the water it breaks the connection and the alarm stops. It has a long cord stored inside that pulls out of the bottom so that it can be mounted on the wall and the sensor can be placed on the floor. If you choose to stand it on the floor, place it were it won't get knocked over easily because it won't work in this position till the water is about an inch deep. You want the contacts to be at the lowest point so as soon as water appears it triggers the alarm. It would have been nice if there were stabilizers on the bottom that either flipped out or snapped onto the unit when it's used in the standing position. If you think you might need to add more stability to it and your handy, it would be an easy fix. I would suggest placing it somewhere were it won't be knocked over yet still visible so that you can check it easily and you should be just fine. If you have children and pets that's another story. It also would have been nice if it had a low battery warning like smoke detectors. This is something you will have to keep an eye on or it most definitely will not warn you with a dead battery. August 16, 2016
Rated 5.0 out of 5.0 by Easy and effective Very easy to get up and running - just insert the battery. I like that it can be used as is or the sensor can be removed to place where it is needed and the casing can be mounted elsewhere. This accommodates several different kinds of spaces where I needed to install them. Nice produce. July 19, 2016
Rated 5.0 out of 5.0 by Works as Advertized The water alarm is used in the crawl space under our pier and beam house which only gets some water after very heavy rain storms. The alarm is used to alert us when excess water is present so we can use a submersible pump to drain the water out. The alarm has the option to put the sensor up to several feet from the alarm unit. February 10, 2016
Rated 5.0 out of 5.0 by quick cheap water detector these were easy quick and reasonable much better than finding the hot water heater in a closet flooded because you didn't open the door July 20, 2016
Rated 5.0 out of 5.0 by Works as advertised We got this after a long saturday of fighting with our washing machine that decided to throw up some missing socks. Fortunately they ended up in the pump trap. Unfortunately accessing the trap required disconnecting the hoses. Since the washer/dryer are on the second floor we wanted to be sure we knew if they started leaking. It turns out they were fine but a line from the AC unit ran into the same drain and I didn't put it back correctly. Shortly after turning on the AC I heard the alarm. It is pretty sensitive so saved a real mess and probably a lot of water damage. Well worth the cost. Just got to remember to replace the battery. May 17, 2016
