Only getting a trickle of water from HOT side
I'd sure appreciate some ideas on this...
After camping a few weeks ago at a full hook up campground, I'm now only getting a slow trickle of water from the hot side in our 2000 Itasca SunCruiser and it's 2 year old Atwood 10-E hot water heater.
Here are some specific observations I've made...
It seems like there has to be a bubble in the HW heater that I'm not draining, or some sort of problem with the heater itself (like a second, internal, one way valve that's stuck). The fact that I can get normal pressure flow out of the HW side for brief periods seems to tell me that there isn't a problem with the HW plumbing lines. But, beyond that idea, which I don't know how to fix, I'm stuck.
Anyone out there ever faced this before? Any ideas? I'd be GRATEFUL!
Thanks much!
Dave

- Start with main house tank EMPTY and HW tank EMPTY
- Fill the main tank. I hear the pump filling the HW heater tank.
- I'm pretty sure I can hear the HW electric heater working.
- Once main house tank is full and HW tank seems full (i.e., pump has stopped running), I get GREAT pressure out of the HW side for a few moments, followed by a copious amount of air, followed by just a trickle of water on the hot side. Cold side water flow & pressure are normal.
- Opening the HW heater pressure relief valve (on the heater), I get lots of high pressure water coming out of the pressure relief.
- After I do that (release some of the water from the HW tank via the pressure relief), I get flow from the HW side for a short period ... then back to just a trickle.
