When at Eastern States, I was talking about the pump by-pass to fill the potable tank from city water and you made the comment that you did yours with a solenoid valve and a level contact level sensor to shut it off. (Unless I misunderstood.)
I have an addition to your good idea.
I frequently load the potable tank to half just because I don't want to carry the weight (~170#) of the extra water. Well, you could do that even more easily than I can with just another set of switch selected contacts in the side of the tank.
While I like the idea, I don't happen to have a solenoid valve or a contact level detector lying around. I would want it to be 12VDC as I have frequently taken on water with no AC power handy.

Matt,
You're right. In fact, one could easily have a stack of well-nut contacts
in the tank, switch selectable for the cutoff -- or, with a functional tank
level gauge, connect the cutoff circuit to it. That's just not how I did it
on the now-gone SOB. I haven't gotten so fancy on the GMC though there are
times when it would be nice. Maybe that's a winter project.

Mike,
That recirculation idea (which I implemented here at home 6 years ago, with
a pump, because the water heater is 85' from the showers) made me remember
the delivery of my new 40' SOB in '97:
During delivery preparation and system testing (with me watching) the
"technician" couldn't get the water pump to stop running. After he rounded
up a replacement (probably cannibalized from another coach) and installed it
with no improvement, I innocently asked "what's this valve for?". It was
the city water tank fill valve. With it open, the pump's output fed
directly back into the H20 tank. I think the "bad" pump probably pumped 100
gallons 'round'n'round about 50 times. :-)
The quality of the support from that dealer never did improve -- I've got
lots more tales. :-(

Sometime Ken, You have got to tell us more.
Do you think that the subject person ever figure out what happened and how silly he looked?
