Yep! I started having the same problem. I really believe it is the three way ball valve that started leaking through all of a sudden. To buy the original part from ShurFlow it costs around $400.00. I am planning on just buying a three way valve for around thirty dollars and change it myself. I do not need the plate that shows what the valve is opened to, filling tank or city water. The plate just shows when pointed in one direction or the other what it is doing. Not important to me. So it looks fairly easy to change out, we will see after the weather warms up a little. Too cold right now to do anything outside. LOL!
