Water loss

When I fill my fresh water tank to go boondocking its only 2/3rds full when I arrive. I have a '05 Itasca Sunova. Any ideas?

It's most likely siphoning from the tank from the overflow drain. If you add a loop, like a trap in the line, the siphoning will stop.

Whatever you do, DO NOT block the overflow vent. The coach will literally explode (ok - a little dramatic) if you fill the tank and the air has no where to go.

We just finished repair to a coach where the owner blocked the overflow drain for the same reason -- about $18K later.... Bent all the steel framing in the floor, slides, broke the kitchen side walls, counter, flooring, it goes on....

P.S. It wasn't a Winnie.
