Thanks. Being new to this arena, where would one find an approved holding
tank ? Is this something that would only be available at a marina ? Would
it be possible to just dump it into your homes waste system. I have a clean
out trap at home with a 4inch pipe as the opening. Seems like I could just
unsrew and dump into there. Or would that make no sense ?


We used a porta-potty for years on a small cruising boat and
poured it out into the toilet at home; we're hooked up to
city sewer and it's no problem.

Don't dump it into a system that flushes into a septic tank,
though. Unless you add a bacterial treatment to the
porta-potty tank, rather than sterilizing chemical mixed
with perfume (which is what most people do because it's
cheaper), the stuff in your porta-potty will kill your
septic system DOA.

Jim is right about using marine or camping toilet paper. It
will break down much better. And make sure that it doesn't
get caught in the flush valve, since that ruins the seal.

Many people complain that the porta-potty always stinks, but
this is because of a problem with the way they are using it.
Ours (a Thetford 135) was a well made little unit and even
after a couple of days use, gave off no odor at all.

Hope this helps
