T&T: Rigid Plumbing

[Dan Winchester]

There have been numerous posts about rigid plumbing and the pros and cons.

I have several questions?  The standard recommendation seams to be SCH 80
PVC.  Has anyone used standard ABS pipe.  This pipe has been used in motor
homes for years and I just got through restoring a 1973 GMC that used ABS
and it seamed to stand up well to all the vibrations that it went through in
the last 34 years of use.  Of course on an RV there is not the permeation
issue to consider.

Has anyone really experienced any cracking or leak problems with any ridged
plastic drain pipes?

What is a good size holding tank for cursing the Puget Sound Area and the
Inland Passage to Alaska for a 48 foot boat with normally one couple aboard
and sometimes another couple for guests.
