Was dry camping this past week. Fired up the water heater on propane and I could hear it fire up and heat from the outside of the RV. When using the water over the next couple of days, I notice that the water was warm, but not hot.
Someone suggested that I may not de-winterized properly and utilized the by-pass.
Not sure if that's the problem, but I have attached a couple of pix of the by-pass. Is it in the right position? and would this be the cause of low water temperature?
