Toilet to tank, toilet overboard and through hull. Plus pipes and hose. I am
aware of PVC of course, but I'm not certain of its durability or its
permeability by vapors and toilet gases. These are valves made from a fiber
reinforced plastic that is popular in the chemical industry. I am not aware
of its name, but it is much stronger than PVC.

Peggy,
I need a series of 1.5" ball valves and other toilet and holding tank
plumbing items for waste handling.

Why do you think you need ball valves in sanitation system plumbing?
There's not a lot of applications for 'em.

What else do you think you need?

Please recommend for me the best material for waste handling.

For most applications PVC or marelon. Anything but metal.
