Frozen hot water line

[Erlingiii]

We had our hot water line freeze up somewhere on our fleetwood discovery 39L, I did all your basic preventative measures(furnace/heat lamp), even blocked one of the furnace ducts to push more flow into the basement. Spent the day trying to find the cold spot but the supply line to the heater is untraceable, anyone have ideas? I inspected all the compartments and there is little or no signs of the plumbing

Do you have water in the fresh water tank? If the line is frozen to the tank from the city water side you could try using the pump and use the fresh water tank till you find the problem

Some of Fleetwoods models had the hot water line run right next to the outside wall at the bedroom.


The guy next to us in St. Louis had his freeze, sometime in the past, so hard it broke the outside wall.

I emailed fleetwood last night and when I got up this morning the plumbing schematic was in my inbox. Turns out they run the line to the water heater in the floor under the lip of the slide room(very difficult spot to keep warm, let alone heat up through the carpet). Fortunately, it was sunny this morning and that side of the coach faced south, hot water again! Not much I can do to prevent it, but I think I have spotted a weak spot in the hydrolics bay near the low points.
