I just finished a hardscape project for a retired engineer. I set up an excavator to keep him busy and away from my work, he got bored and decided to test irrigation that ran under the hardscape. He capped all the lines on the 2 inch to do a leak test prior to flatwork and blew out the city meter.
I am thinking about replacing the toilet with a gravity flow model and just use fish oil in my diet. Way too much consideration to flush one of these units for me.

There should be a vacuum break right on the air/water separator but it may depend on what toilet you have. (You may have said earlier, but I'm too lazy to look back, lol). In my LXi there was a general plumbing vacuum break buried beneath a removable panel inside my hallway closet mounted on the wall. In both cases there should be a trap downstream to block fumes. The issue with my Headhunter toilet is there's no air gap between the fresh water and the blackwater in the toilet bowl. The pressurized fresh water enters below the bowl water line, macerating style. The microphor toilets that I've worked with have an air gap so there's no way for black water to back flow into the fresh water tank. HTH's

Greg, before you settle for a gravity flow toilet, you might want to consider another option. I think there is some horizontal plumbing in an LXi that makes a gravity flow toilet not to work efficiently. This is the toilet model I have in my LXi. I think it is made by Thetford. I'm presently away from my bus but I will be back Monday. If this interests you, I can get you more specifics then.

This toilet works excellent. It has a lite flush and a heavy flush operation with the push of a button. The electric controls go to sleep after a period of non-use.
It seems so unnecessary to have to deal with all the pneumatics associated with the Microphors.
