Customer Reviews

I have the sensor hanging in my sump pump. It did go off one time when my power went off and I could hear it from upstairs.

So I bought this item for my sump pit. The sensor has a suction cup, and the top of my pump float switch is smooth, seemed the perfect place to attach the sensor -- if the water keeps rising when the float is at the top, this means the pump is being overrun (or broken), and I want to know about it pronto! Big mistake.
So I tested the alarm by dipping the sensor into a cup of water -- worked great, as promised -- and stuck the sensor on top of the float switch, which was the only suitable smooth surface there. Yet after recent record rains when the water rose way higher than the sensor (it was at least 1/2 foot under water, for several hours), the alarm remained silent. Puzzled, I started experimenting with it more to figure out why. And, sure enough, if you lower the sensor into a cup of water slowly keeping it horizontal, a large air bubble remains in there between the leads and prevents it from working! This looks like a big design flaw.
Now I have it in the pit vertically, aligned such that one of the openings in the sensor enclosure is at the top, to allow the air to escape. Placing it this way wasn't as convenient as before (there's no smooth flat vertical surface to attach the suction cup to), but hopefully it will make it work better next time, if there's one.
So the bottom line is, make sure that your sensor is not attached horizontally.
