On or the other of the two seals is shot. Usually the flush valve seal is the
culprit.

Seriously, if you can smell the contents of your porta potty when it's closed
up, then something is wrong with it.

It is entirely possible & practical to have an odor free head.


which as you say, means a lot of trips to the dump out. I guess
I just rather not do that every other day.

Yeah, me too.



Of course, holding tanks can get nasty too if you don't do the
regular maintenance. One of the other instructors had a very fun,
exploding holding tank experience, when he decided to do a pump
out. Apparently, no one had bothered in a couple of weeks... yuck.
Glad I wasn't there.

That's gotta be one of the perks.....

A common problem (seen it four or five times this summer with boats in our
marina) is a clogged holding tank vent. Makes it difficult & slow to empty the
HT and tends to make it splatter when trying to pump out.

But a lot of people would rather sit around and drink beer & brag instead of
either 1- going sailing or 2- fixing their boat so it will work properly. Human
nature, I guess.
