So here's an update with a different problem. Got into the basement and found the panel that JW mentioned (thanks, JW). Got it off and sure enough, the water heater was not in bypass. Purged the tank (again) to get as much of the pink stuff out as possible, refilled it, and fired it up on propane. (No AC available at that point.) This is a 10 gallon Atwood heater, by the way. Had a Suburban in my old rig, so Atwood is new to me.
Must have taken a half-hour for the burner to light, but eventually it did with no intervention on my part. Waited a good half hour to an hour until it shut off, then ran the hot water at the kitchen sink. While the water was warm, it never did get hot. Same for the shower and bathroom sink Must have run it for a half-hour before the heater fired up again. So, with all that, I'm thinking I have either a faulty thermostat, or the mixer on the back of the heater is adding too much cold to not enough hot.
Has anyone else run into this and have some ideas to share? I'll take all the advice I can get.
Thanks...
