Fresh Water Filling

Hello!

The last time I put fresh water in, the input valve (solenoid?) appeared to be reluctant to tightly close once I was done filling the tank. And the surface area around the input nozzle is a bit warm.

We tend to leave the water pump switch in the "off" position as a general practice.  When we leave it "on" there appears to be air in the system when we turn the pump on.

Can this situation cause any harm?

best, paul

Paul,
        If the solonoid valve does not close completely the system cannot hold pressure. When you turn the pump on, it wants to pump water back into the tank thru the leaking solonoid valve. If the valve seating is really bad the pump would running continously. A slight leak would take some time to bleed off the pressure and then run the pump to presurize till cutoff pressure of pump is reached. Probably won't hurt for short term use if you always shut pump off but eventually you might have the pump run continously and burn it out or blow the fuse. This happened to me and for a temporary fix I took out the solonoid valve and put a ball valve in so that I could manually shut off the fill line.
I disassembled my solonoid valve and it cleaned out easily but you have to drain the tank. A few days ago I wrote about how I replumbed to eliminate the fill/house line connection.
Good luck,
Rick
