Head removal

[HoosierDaddy]

My '93 has an air pressure operated Sealand toilet. I'm thinking of doing some remodeling that would involve moving it. Is the mounting and drain requirements similar to a regular household toilet? What size drain plumbing is required?
Thank you!

I have an 88 coach with the same toilet and did remove to put a marble floor down. The drain pipe is approx one and one half inches and if you look in your bay under the toilet you should be able to see it. The air operated process acts as a masurater and breaks everything up with the air and water acting as compressed air so the waste goes into the tank as small peices.
They are great toilets and I sure prefer them over a standard toilet because I live in my coach full time and have never had and sludge build up in the waste tank.
I also installed a shut off valve on the air line to the toilet in the bay so when I work on it I don't have to drain the entire air system.
It is easy to remove and work on so have at it.
