I have spent some time eliminating a leak from my original Dometic CTS3110 toilet. The end result is a complete replacement of toilet and now I have an unused 2nd CTS4110 cassette that I do not want plus a SK5 access door that I did not fit to the MH.

Additionally I have a new Lower Bowl seal that did not get installed.

Seal cost $39 and am looking for $20 + postage

SK5 door came with the new toilet, is available for $104 am looking for $50 + postage.

Cassette cost me $379 and I am looking for $180 plus postage. Available in Macedon Ranges north of Melbourne.

Lower bowl seal fits between the ceramic bowl and the top of the cassette

The SK5 kit can be used to add a lockable door pretty much anywhere you want another opening

The pristine cassette

Donmar,

Yes it is.

Cassette is SOLD. I'll list the other items separately
