Ok. Here's the issue.
After 10 days of the above issues and no hot water, we left and stopped at a campground in Nashville on way home. Didn't even unhook and on way home today.
I tried the hot water again. On FWT it still won't light. FLT light comes on every time.
But guess what? On city water it "works". It still fades in and out but from hot to warm instead of hot to cold.
Water pressure!!! No other difference.
So I have a hot water system that won't work on FWT at all.....won't work on low fliw....and only sorta works on full pressure.
Concept is wonderful....execution sucks.
