Hi Bob,

I'd love to plumb with PVC pipe, but I've heard
that the flexing of the boat causes it to develop
cracks over time. Is that true?

Have you considered a composting head?
Seems it would save space and cut out all the plumbing
and leaking crap. Not cheap.

Here's somebody who uses one and give a good account of his/her
experience with it.
