Water Heater bypass valve.

Same thing happened to me last year as I have the Anderson valve set up. Only thing I did try last year for 1st time was blowing out the lines w/ air. Because I was on a tight deadline to get RV to storage place, I bought a water heater hose bypass (like 10-15 bucks) to get me thru things and worry about it in spring. Had to take apart the basement wall and such, but was able to get things done. This spring, replaced a check valve on water heater side. No probs all summer. So when I went to winterize it this Mon, I followed directions at docking station, flipped lever to bypass and turned the A-valve to winterize and no probs. Perhaps when I did the air thing, I messed things up......dunno.

I as well thought the A-valve or bypass valve went south and was going to replace the A-valve. About dropped my eyeteeth when I saw it was about 100 bucks and looked to be more involved than I thought. Found a place in OH that had the exact same type of A-vlave just not from A-valve co for a fraction of the cost. Ordered it just in case the check valve on water tank didn't work. Now I cannot locate it here in the house! Go figure. Anyways, I believe I put the cart in front of the horse last fall trying to be in hurry and messed up the check valve on water tank.

Same here , plus I got one fitting off the bypass valve. The A valve I am careful with ,, been told to get the pressure off before switching to a different mode, or it could blow an O-ring. I am going to attempt to get that fitting back on the bypass, have my doubts . If I can't I will buy a new bypass , and replumb . They are about $60.
