Review on Reliance Controls THP205 Sump Pump Alarm: Flood Alert, 9V Battery, 6 Ft Wire Sensor, 105 Db, White by John Souza

This is an alarm clock I hope you never have to use. direct current source. Comes with a screw/anchor for wall mounting and a weight if you want to hang the cable in the hole. The picture of the probe is not what came to my mind. My probe is red and has 2 metal pins about 1" apart which looks like a superior (upgraded) probe. The alarm is loud enough when the house is quiet. My pump is in a rarely visited basement, so the sound is a bit muffled. It's good to have a second pump on hand, when the alarm goes off you know you have a high water level, but without a second pump there's nothing you can do about it. This. During testing, the alarm turned out to be very sensitive. The only complaint about the probe from the alar and the case to the probe could have been a little longer. Conclusion: Works as intended, why pay 2-3 times more? It's basic signaling that does what it's supposed to do.
