James - We have the same coach, and ours also has the two Fresh Tank Fill switches - one in the Wet Bay and one under the countertop in the galley. Our galley switch is inoperable, always has been since we purchased the coach. I don't know why it's inoperable, but I suspect it's easy to forget it's on when filling the tank when inside the coach. Several times I have started the tank filling and got to doing something else, then, fortunately, hear water overflowing the tank. Our switch in the galley is wired up but just doesn't make the Red Hat solenoid open and close.
