Thanks for the responses. We did use some paper towels to determine where it's leaking, basically between bathroom floor and basement ceiling. None of the exposed piping is leaking. Wondered what else could do it.
Chris, I don't have much experience with the vacuum breaker---is that a correctable flaw or just a fact of life? Certainly explains why it does it only occasionally. Appreciate your insights.
Thanks!!
The vacuum breaker problem is a known issue, per
this post from 2010. It is an easily replaced part. Call Thetford, they may be willing to send a new one free of charge.
