I suspect you had a blow-out of the toilet's vacuum breaker. Here's a line from an email I sent to
Dometic Sanitation Corporation
"I had a blow-out of what appears from Dometic’s online diagrams to be the vacuum breaker (Item H in ‘Dometic RV 300-310-320 series toilets installation and operation owner's manual’.
Diana replied "Your toilet is still covered under warranty so I will send you a replacement vacuum breaker
" and she did. Great service from Diane.
Easy? Was for me. Hardest part was getting my big melon head in position to see what I was doing!
