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

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?

Why would it be full of water before you ever use it???? Unless you
tried putting hot water in it??? You don't heat hose from the inside,
Lloyd...you warm it from the outside. You just stick the end into a pot
of boiling water--which can be a little hard to do in some locations--or
you just turn a blow dryer on it (from a distance that isn't likely to
burn it)...and let it run for a few minutes. Because you don't want to
risk damaging the hose, you do need some patience.

Noooo! If you do that, the hose will never seal.

Same way you should have put it on: warm it with a blow dryer. It
should soften up enough to come off.

I used a heat gun and spray silicone to get my sanitation hoses on the
fittings. It was tough, but worked.

Ouch again!
Peggy...you are BAD!

I had better stay on your good side. TheMirage 33 I crew on is also having a
problem with a head that was replaced only two years ago. We sailed on a
six hour trip yesterday without toilet facilities and something has to be
done.
I'll get the toilet model and make this weekend.
The problem... we can't expell contents of bowl.
We're guessing we may have a blockage in the line
or the pump mechanism is faulty
or the y valve that used to direct waste water
somehow got turned to the holding tank line that has
been cutoff and capped and is stuck there. When
we turn this valve (on a1983 boat) no resistance is
felt.
We don't use the holding tank as the dirty water is expelled directly
through the thru hull
I'll post again with more info. later as the boat is at our summer club in
St. Margaret's Bay and we don't have the full service
repair people on hand as we would at the Squadron.

The entrance would be about 15 nm south west of Halifax Nova Scotia.
It takes us between 7 and 8 hours to sail club to club.
note: our summer club is approx 44 degrees 38.15 minutes N
63 degrees
55.12minutes W

Prob'ly not...unless you've had guests aboard who've flushed something
they shouldn't have.


or the pump mechanism is faulty

I think the problem is in the toilet.

If it's a Jabsco, the wet/dry valve has prob'ly failed--very common in
Jabsco toilets. That valve is just a little "door" that swings to open
or close the flush water inlet...it hangs, and when it does, it creates
backpressure in the toilet that feel like a clog in the discharge line.

If the toilet is a Raritan PH II, there's an air valve on the front of
the wet dry housing--a little flat square nut with a hole in it that
looks like it's molded into the housing, but is actually threaded in. If
it gets clogged, it'll create backpressure, preventing the toilet
from flushing. The cu remove it, clean it, wrap the threads with
teflon tape and put it back.


or the y valve that used to direct waste water
somehow got turned to the holding tank line that has
been cutoff and capped and is stuck there.

If that were the case, waste would be backing up into the toilet.

If the toilet is something other than a Jabsco or PH II, I'll need more
info to trouble shoot it.
