PVC. In fact Sealand recommends it over hose. Much less subject to odor

The potential for leaks increases geometrically with the number of
connections.

A simple of hose has two (2) process connections.

Replace with a piece of PVC pipe and a short length of have on each end, you
have 4 process connections.

Maybe on a stink boat, but never on mine.

I'll stay /w/ hose and replace as needed.

Hi,

I'd have thought wrapping the hose with foil tape would take care of
any permeation problems.

cheers,
Pete.

Sch 40 pipe (white PVC), ABS (Black) and sch 80 pipe (gray PVC), are rated
for sanitation service, but who in their right mind would put it on a boat?

White PVC has no UV inhibitors and if left in the sun, will probably
fracture in less than 1 year in a place like SoCal or Fla.

Who in their right mind would run their sanitation hose on the outside of their
boat? :-)
