What 's special about marine-grade bilge pump hose?

And also fwiw, I wouldn't use corrugated hose for
anything on a boat, anywhere.

Why not? It's pretty crush proof and kink proof. The stuff I'm
familiar with has a fairly smooth bore.

One drawback is that it's supposed to be terminated with wire hose
clamps which may be difficult to get in stainless.

For through hulls I'd look at using some *high* quality hose from the
through hull up to where the 'goose neck' loop would be, and then use
black corrugated hose after that.

But that's what I'd do. It's your boat...your choice.

Anyone had a bilge hose or non-engine hose failure? What sort of hose
was involved?

Hi Pete:

Agreed!
It aint brain surgery.

I've had a sink drain hose fail without warning. It was a cheap currugated
hose. A fair bit of Atlantic came in before we figured out what had
happened. A bad day that I don't ever want to repeat.

I see. Did it split on a bend, at the clamp, or just in a straight
run? Was it this sort of hose? :

The hose was pretty similar to that stuff. Some hot water was put down a
galley sink drain and water started coming out of the cabinet under the
sink. It took a while to realize that it was seawater and that therefore
there was a lot more available than the gallon that had gone down the drain.
As I said, a bad day. I got religion.

$$$$ hose religion I expect...

Yup, and that religion has added up to 0.3% of the cost of owning that boat
over 25 years.

Because corrugations are traps that grab onto sea water minerals, bilge
"glop," waste, and anything else that isn't pure clean fresh water.

That's another reason. Wire can cut into the hose too.

Lots of people! Cockpit drain hoses, clear water hose used for toilet
intake or sink drains...and yes, bilge pump hoses. Corrugated hoses once
were common on boats, but are no longer recommended for any application,
above or below waterline.

Peggie,

Are you talking about the kind of hose in this picture?

http://home.maine.rr.com/rlma/Bilge.htm#Sump

It's almost perfectly smooth on the inside and quite a dense looking
plastic. The standard hose clamps seemed to make a good seal. My
pumps discharge above the waterline so there is no standing water in
the hose. I usually pump the bilge with the hand pump before the
level gets high enough for these pumps to run. It's the only 1 1/8"
stuff I could get at the time.

Do you think I should replace these hoses?

I can't tell from the photo, Roger, whether it's corrugated or only
reinforced. If it's rated for the application--not only for below
waterline, but for whatever goes through it and the temperature of
it--it's ok. If it's not, I'd replace it.
