Ok so for those that read my other post in the lounge, sorry wrong forum, you are aware that i got to wash my tile floor this morning with 50 gallons of salt water. Well that is all cleaned up now and I have replaced my check valves with flaper valves which are working like a charm. Plus they are clear so I can monitor them. All the water stays put when the pumps go down, but now I have a new problem.
First let me lay down the closed loop system so you can make sense of it. Starting from the sump water is picked up by a little giant pump and pumped into a frag tank. Water is overflowed in the frag tank where it is picked up by another little giant (same one) where it gets pumped back up into the main tank where again there is an overflow down into the sump to start things over again. There are ball valves where needed so I can control the flow here and there due to running two pumps.
Now..at the second little giant I have a series of ball valves where I can route water directly into the main tank, or I can route it through the chiller. So the problem is, with everything running fine, when i change the ball valves to route water through the chiller the GFI snaps and kicks the tank off line as everything for the main tank and both pumps is wired through a GFI. I touch nothing electrical just the path of the water. The main circuit for the house does not pop, just the GFI. Any ideas???
I am thinking a bad GFI - they are so sensitive. Sorry for the long post, I tried to avert further questions to provide more possible solutions.
In any event I am flood free now and in the future
