148 is recommended for grey water and as a bilge hose but it will not
stand up to odor permiation in toilet applications. 144 is somewhat
better but not much. 101 is the standard black water hose and Sealand's
Odorsafe is the best.

You don't need a whole lot. I talked to Ed McKunen, president of
Sealand (and not my favorite person) about it. We recommend making your
longer runs in Schedule 40 PVC with short lengths of Odorsafe to absorb
vibration and movement.

I'm sure there's a good reason - but my initial looking discloses two basic
types of sanitation hose.

Both claim the same purpose (keep the stuff and the odor inside while on the
way outside), but there's one which is 3x the price of the other.

What's the difference, other than the obvious price? Easier to use? Won't
let the odor/seep through, ever, vs some number of years? Stays whiter in
more conditions?

The difference, in boat money terms, is pretty insignificant, I'd say (some
couple-three hundred bux for the standard 50' roll), but if it's not needed,
I can use that couple-three somewhere else.

Anybody used both (e.g. "148" vs "Sealand") who can give experiential input?

Thanks.
