Water heater issues
We have a suburban model SW6DE water heater in our camper and have been having a lot of trouble with it. On propane, it always overheats and blows the pressure relief valve. I replaced the pressure relief valve, and both the high and low thermostat. Still overheats.
I recently replaced the electric element. Since then I have intermittent hot water. It will go from warm, to cold, to hot, and back to cold. It does the same thing on propane now as well, only water is hotter, but still intermittent.
Tired of the problems. Ready to buy a new hot water heater. Any other things to check?
