It is amazing..... more like unacceptable.... that Thor continues to make new units with this problem!
The problem is the Vacuum Breaker Valve that is supposed to prevent water from backing up from the black tank into the plumbing.
For the past 3 or 4 years Thor has consistently installed either defective Vacuum Breakers or they have installed them backwards in the San-T-Flush plumbing.
We just took our 2018 Outlaw 29H out for the first time since they fixed our San-T-Flush issue. It worked great now that it is fixed working properly and much better than pouring water into the tank from the toilet.
Our dealer even made an access panel to make it easier to replace the Vacuum Breaker if it ever fails again.
