My p-bus uses a headhunter toilet so I'm currently (temporarily???) out of the Microphor world. The headhunter toilet poses its own set of special challenges. For those interested, the headhunter toilet is a macerating design. It's super simple but it relies on some critical check valves and if those valves start leaking, evidenced by a diminishing bowl water level, it could mean that toilet water is draining back into the fresh water tank! Eek! Sigh! Every toilet seems to be somewhat cursed! LOL!

David, not sure if you are serious about the back flush but this is one of my fears with an unfamiliar system. the new to me air operated toilet in my lxi has issues. I need to undo PO re engineering and make sure the plumbing code safe measures are followed

In my 94 there is a atmospheric vacuum breaker in line with the tank flush system that I believe vents sewer fumes into the wall of the coach where the device is located. I often thought of removing it but have fear of the impact if there is an issue. one problem with AVB devices is they vent by default when not pressurized

Are there atmospheric vacuum breaker devices in the LXi that I need to make sure are inplace?
