A few weeks ago, I asked if anyone knew of a water sensor that will turn the pump off if it detects the presence of water. Someone sent me to SmartHome.com. I want to thank who sent me there.
I purchased a water sensor with a built in relay from SmartHome.com. It model # is 89461 - Water Alarm w/Relay Output. I used thermostat wire, the a red and white wires in pic to connect the built in relay to a 20 amp GFCI. I connected the red and white wires to ground and neutral on the GFCI out. The relay switch is normally open. Connected a small extension cord to the line in on the GFCI. If things are wired correctly, touching ground to neutral will trip, turn off, the GFCI. Put the little green water sensor in water, alarm goes off and GFCI trips. I plugged my water pump into the GFCI and plugged the extension cord going to the GFCI where the water pump was plugged in. Some GFCI's don't like motors. MY pump didn't trip the GFCI. If there is a plumbing leak while I'm not home I may have a wet floor when I get home, but won't have a flooded basement.
If anything screws up, it is as simple as unplugging the GFCI and plugging the pump back where it orginally was.
Hope this may help someone.
