As for whether to use hard PVC....it's only recommended for long
straight runs. And it also should be "soft coupled" to anything rigid
(toilet, tank, y-valve, macerator pump, thru-hull) with enough
hose--about a foot--to cushion it from shock and flex. If you don't, it
can crack. So unless you have long straight runs, I suggest you go with
the AVS96 hose Keith recommended.

Peggie, could you elaborate a bit on the "solely for long strait
runs"-part. As you describe it, I suspect only a very few
installations are suited for using hard pvc.

I installed hard pvc by using a heat gun and some 45 degree bends.
I made "the soft connection" on both ends and I used rubber fasteners
every 30-40 cm to ensure proper fixation and thus reliability.
In my view hard pvc (installed with care off course) is superior cause
it's really non-permeable and *stays* non-permeable. Next to that it's
a lot cheaper than these top-quality hoses.
