    I've got a customer that I have replaced solenoids on several valves, including the master several times over the past year. They are the cheap Weathermatic valves, which I know have crappy solenoids. Checked the power supply and output at the controller, everything looks normal.

    Besides replacing the entire valve, what could be causing the repeated shorting of the solenoids?

    Did you check your amperage for the circuit?

    Lightening, power surges.

    You answered your own question-cheap Weathermatic valves and crappy solenoids. Go to and buy as many as you need-I've had no issue with these:

    The weathermatic solenoid issue is well known however it’s been a while since then. Likely you are replacing the defective solenoids with more defective solenoids.

    Isn’t there a buyback program for these or labor and parts weathermatic was doing for a while?

    As far as I know I've been using new stock.

    Did check amp draw and it was as expected. Had found the common and a couple of the valve wires without wirenuts in the dirt at the splice going into the garage with multi-strand, but cleaned that up last time I was out.

    Will likely just replace the valves with PGV's. The Hunter solenoid is the one I find being replaced the least around here.

    Just swap out every last square solenoid with the new round one. Job done.

    After I switched WM solenoids to the versions with white wires, problems over.

    I know for sure I've been using the ones with white wires. So I'm wondering what else would be causing this to continue to happen?
