We just purchased a new toy hauler. The first and second and third shower was horrible. Low water flow and either the water is too hot or too cold, won't adjust, any ideas? We had an on demand in our house and we threw it out....dang.
Generally temp rise will affect flow of warm water, as will incoming flow rate to the water heater. Increase of the cold to temper the water and you slow down the flow, essentially shutting down the heater.
