This is the best flexible hose to use, where you need to connect the
rigid if you use it: http://www.aussieglobe.com/avs96.htm. This is what
Sealand used to sell as Odorsafe, but they supply something else now
that doesn't work as well and is more expensive. As far as getting rid
of the current odors, a good scrubbing with simple green or any good
cleaner works great. If that fails, PureAyre odor eliminator seems to
work great. http://www.pureayre.com. No commercial connection, just a
satisfied user.

I second Keith's recommendations--both hose, and what to use to get rid
of the residual odors. I've just discovered PurAyre, and from the
feedback I've gotten it WORKS!

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.
