The problem is the fitting, Lloyd...you'll never get it onto a gray pvc

Stop by your local boat store and pick up a nylon 1.5" fitting...the
barbs on those are 1.5".


Not sure what you mean here. The one fitting is the plastic 1" - 1 1/2"
adapter that I bought at a marine store (and it says "1 1/2" right on
it!). The other is the existing brass suction-break that was used with
1 1/2" diesel filler hose.

Never mind what it says...measure the OD. You'll find that nominal (what
it's supposed to be) and actual (what it is) aren't always the same.

PVC plumbing fittings aren't made just for the marine industry...they're
the same PVC fittings that are used throughout the plumbing industry.
I've never found anyone who knows the reason for it, but ALL gray pvc
1.5" thread x 1.5" barbed fittings are actual 1 5/8" barbed. But they're
all marked 1.5 x 1.5. This is only true of 1.5"...for all other sizes,
nominal and actual are the same.


I measured both fittings: the plastic (donno if it's pvc or nylon) is just
a hair over 1.5". Some hot water and soapy got it on fine. The other one
is also a hair over 1.5, and yes, the two fittings on the suction break
are about 1/32" different.


Btw...you said brass...most marine fittings are bronze. If it really IS
brass, I wouldn't use it in a sanitation hose...urine is corrosive and
brass is likely to get clogged up with vertigris.


Must be bronze - I bought it a a marine store (at typical marine price!)
and they knew it was for a holding tank.


Not sure I can get a hairdrier at this hose.

Lloyd, if you can get at it to work on it, you can get a blow dryer
close enough to it to warm it a bit. That's why they make extension
cords.

Well, I CAN'T really get at it to work on it: only about 1/4 of it. I
tried heating it with a steam-cleaner (Now it's Really Clean...), and as I
felt it getting cold again almost immediately, I realized (duh!) it's full
of water, which is at least thermally connected to the ocean through the
bronze thruhull! No way I'm getting this baby hot!

Should I drill a hole in the hose and let most of the water out (it's
slanted down, so water in the fitting will still be there...)? Any way I
can cut it off without damaging the fitting?
