Yesterday I had a problem that completely baffled me. This 2008 Bounder 37D is new to us, so I'm still figuring things out. This is our second outing in this MH. Went to use some hot water and found it was barely warm. Thought "water heater", but it was full on HOT water. Came back inside and turned on the kitchen water and ran awhile, still warm. Turned on the bathroom water and the kitchen water got HOT.
Called the dealer we purchased from and talked to the service manager. He said the bi pass valve must have gotten turned. I checked but it was in the normal position. I turned it off and back on and now I have HOT water again at all locations.
While it is fixed, I can't figure out what was wrong in the first place. Don't want to go through this on a regular so I'd like to know what caused the problem and why moving the bi pass fixed it ?
