Hey guys, hope this is right section for this...
We installed a solar controller and all was good until today. The solar panel has a pinhole leak, and I assumed when the controller shut the flow to the panel off the leak would stop...not the case though. I'm thinking the check valve isn't closing and allowing water to flow back to the panel. I manually shut off flow to the panel with the pvc ball valves and when I opened everything back up the leak stopped. So it seems like when flow to the check valve is cutoff the flapper has a chance to close and do its job, but the solar controller turning the valves doesn't give it that chance and the flow continues.
Does this sound like what's going on? Do I need a different better check valve?
