Suburban on demand water heater
I have a 2018 Montana 3920fb which has a bathtub. Believe me we the on demand water heater. The problem is it must run for 7 to seconds before it starts heating. When I do the dishes or wash my hands I need to run the water for at least 10 seconds before any hot water. My gray water tank seems to fill very fast and this is waste of water. As i have to winterize this system there must be a tank with it. As my dealer didn't show me everything there is a switch in the top of the onboard center. Does anyone have advice.
