I also have a leveling valve that is leaking at the valve. At first I also thought the solenoids might be blowing by, but then I actually heard the valve body hiss. A ha !!!

The best place to buy the solenoids is Newell. You can buy them from HWH but they charge more.

I tracked down the manufacturers of the valves(there have been three over the years), but they will not sell to individuals. They say the valve is proprietary to HWH.

If anyone does replace solenoid valves, I would like to have the old ones. I have been able to successfully rebuild some of them. And some of them, not.
