Need help here?? Regarding sump pump power. Specifically standby power. I have created a power failure standby system for my sump pump using a electrical contactor normally closed contacts a 12 volt invertor. Power fails, contactor contacts close, turn on power invertor, level switch comes on in sump hole 12V battaries power invertor to run 1/6 horse pump.
Simple so far, but??? what battaries to use as standby? GE Ultrasound Probe Normal car or deep discharge?? And should they be on trickle charge all the time?? Since they would be seldom used? I can seem to find info about which would last the best??
absolutely brilliant and unbelievably simple. From doing this hack myself and trying to hook it up to an existing previously devised water detector float circuit maker set up of my own, I found that a smoke detector will start to chirp, on the test mode circuit ,with the minutest amount of continuity. What I am wondering though is when I place the wire into my sewer clean out pipe in my basement floor to detect if I get another root ball growing in my sewer pipe and water starts to back up, will it set itself off monthes before the event happens ,just out of shear moisture in the air around the 2 ends of the wire creating a circuit? I will connect and find out over time. I still can beleive how simple and how well this works! Thanks genius boy or maybe girl!!
