Wal thanks for the info. I'm not familiar with Shields  fittings. I'll look
for them.

Joel - Yes!  You can see some pics of mine at 
 No 
smells after 11 years of hard use.  Also, the smooth Shields hose 
fittings are worth their weight in gold.  Actually, that's about what 
they cost!  The only hoses I've had to deal with go to the macerator 
pump, which I have rebuilt or replaced about ten times in the last five 
years.  It's really nice to be able to just slide the hose off the fitting.

Re: Stus-List Holding tank discharge hose

[Josh Muckley via CnC-List]

I had to get VERY creative to solve my pump out hose problems.  My holding
tank follows the chine of the hull so a straight piece of hard pipe
perpendicular to the top of the tank was only going to go in about a foot
before stopping on the outboard side of the tank.  The tank fitting wasn't
a "thru-hull" with threads on both sides so whatever threaded in the top
also had to extend through to the bottom.  The sanitation hose was so stiff
that getting it off was impossible without removing the deck fitting.

In the end I replaced almost everything and ended up with a continuous
sequence of parts that was fully assembled prior to installation.  Deck
fitting -> 2" sanitation hose (exactly the right length to reach the tank
~2.5ft long) -> pvc nipple -> pvc threaded adapter that threaded into the
top of the tank -> pvc sink drain tail that fit very tight inside threaded
section and extended ~12" out the threaded adapter -> another piece of flex
sanitation hose that would reach the bottom of the tank.  I had to use a
clamptite (wire tie) on all of my hose connections so that they would fit
through the holes in the deck and tank.

Installation was a dance between someone on the deck and someone screwing
the threaded fitting into the tank.  Oh yeah, don't forget this was the
only opportunity we had to use 4200 under the deck fitting.

We also found some core rot when we removed the deck fitting.  If you find
the same thing I have some pretty good solutions you might like.  Let me
know.

I don't think you'll be able to use solid pipe between the tank and deck.
I don't know what advantage it would be to use solid pipe inside the tank.
How would you seal the pipe as it goes through the tank?  Best solution for
smelly tanks is to keep them empty.

Good luck,

Joel,
That is exactly what I did on mine and it has worked very well. I didn’t use 
any hose on the lower end, just from the top of the pvc to the deck fitting. I 
would suggest that you keep the pvc section as short as possible to reduce the 
torque force on the elbow.

All, 

My nasty winter project is to replace the hose from the holding tank to the 
deck fitting.  Does it make sense to use a piece of PVC pipe from the bottom of 
the tank to a point above the tank so that the hose stays dry?

Re: Stus-List Holding tank discharge hose

[D.J. Platt via CnC-List]

Hi Joel

Did my hose last year.  The last one, which was actually an exhaust hose, 
lasted 32 years.  I suspect the new one, proper sanitation hose which appears 
to be smell resistant, will out last me.  I would not waste a lot of time on 
PVC unless it is really easy to do.

My two cents worth.

Hi Joel,

I think your idea makes sense.   In fact my tank has two fittings and two PVC 
pipes that reach down to the deep section of a V-birth shaped holding tank.   
One for deck and one for overboard marcerator pump.  No matter what sanitation 
hose you use, it will permeate smell.  Mine were replaced in 2004, and I 
started getting complaints by 2009.  

Sanitation is on my list this winter.  We live aboard in the summer and the 
smell is driving my girlfriend crazy, especially if we don’t pump out weekly.  
I was told through numerous industry folks and liveaboards to replace 
sanitation hose with PVC.  To keep PVC from cracking,  use small section of 
sanitation hose at the ends of each run to absorb vibration.
