Water Heater Woes

25' 2009 FB Flying Cloud Atwood Water Heater. Full-timing in CO at 7500' for 5 years now. This problem did not arise until I started to pull it recently...

I have spent some time on the forums for this problem, though none that really get to the bottom of it.

Water heater fires up appropriately, though will intermittently, more often than not, become weak/quiet, struggling to stay lit. About half of the time it will somehow find the courage to work back up to full, other half it gets so weak that it quits. Then, a struggle with multiple attempts at reigniting, with success about 6-8x trying.

I have thoroughly checked/cleaned/run forced air through the vent tube, checked the patentcy of the jet, and cleaned the exhaust tube. No change.

I have to maintain the vent tube fully vented to decrease this occurrence. If I open the utility door, problem goes away... which would make me think it is choked for air. Though I've trouble-shooterd this...

What gives? All responses are very much appreciated. Thank you.

I would suspect the regulator. Maybe bad propane pressure?

My first thought too. Fortunately an easy fix.

Also moisture can form in propane lines, so once in a while you have to go to the low point (under the belly pan) and open and drain the line. You can even hear the line bubbling if you're outside with the stove top or water heater on.

The chimney can also foul with black oily soot, which does need to be brushed out every once in a while.

I let professionals work on anything to do with propane, and most electrical problems. That said, I'd call around to local propane companies and see if they repair propane appliances - you can pull the trailer to the propane yard, and have them check the whole system stem to stern in about one hour. (probably less expensive than CW or most RV techs too.)

I full time too. We put much more wear and tear on our appliances than most people. After 5 years you're due for a complete propane system check. Get everything back to "like new" condition and you'll be good for another 5 years.

Question. How is your stovetop doing? Slow to light, week flame - that's either not enough pressure or moisture in the lines - because it affects more than one appliance.
Today is a gift, that's why they call it the present.
