Greetings! I was dewinterizing today, and running hot/cold through my Class B. I have a Coachmen Beyond with a Truma Combi Eco water/cabin heat system.
After setting the valves for use, I ran hot water until the air cleared and I assume the tank filled. My Truma and most of the plumbing system is completely visible under one of the bench seats. Everything seems to be working, but I have the following question/problem.
If water is dispensed from the Cold tap the pump stops instantly when shut off.
If water is dispensed from the Hot tap the pump runs for about 7-10 seconds and then shuts off.
When taps are off there is no pump action, so I don't think I have a leak anywhere. When I dispense Hot it comes immediately, so I don't think I have air trapped somewhere.
Any thoughts? Or is it typical and I just did not notice it before as I rarely use hot water anyway . . .
