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.
