The alarm is GREAT! I was sleeping on the top floor of our house. The alarm was by the water tank on the first level. All you do is put a battery in it and unwind the cord. Put the little white piece at end of wires with the 2 sensors on the floor and/or under a cabinet. My husband has bad hearing, but I could hear something shrieking and ran down and stepped in 6 inches of water at 4 a.m. (My hearing is not so great either). Have used these for the last 10 years all over the home. Highly recommend!
i bought mine a few years ago and it is still working. It is supposed to detect water overflow on to the floor from plumbing leaks. the alarm is is always on only when the there is water touching the two leads built-in. To shut off just move it a dry spot.
One might be able to "rig" the alarm to act as a switch that would turn on your pump but it would take some parts and knowledge of electrical. I would certainly not trust it to activate a pump or any other device. It's just an alarm.
Yes,drop wire in sump above water.When water reaches it it will sound.
It should. Alarm may be muffled inside wall and you’ll need to get at it to change batteries every 5 years
Just like chaining the batteries in your smoke alarms which I do on my birthday, I just do it every year. The batteries in theory will last 5 years but I am not willing to gamble on water damage to save a few bucks.
It has to be about 1/8 of an inch or so
You should be able to test unit and hear the tone to differentiate from other units.
As a retired electrical engineer, I know that all the electrical components that make up modern electronics assemblies function at least down to 32 degrees Fahrenheit. I have two Watchdog water alarms lying flat on the basement concrete slab in unheated areas of my basement. Our basement air temperature dips to 40 degrees Fahrenheit in the coldest days of winter, but because I've never had the sensors get wet then I can't be sure that they would have sensed the water and set off the alarm. Buy the alarm and test it under those conditions. They did work for me when I tested them under other conditions.
