Head discharge hose clogged with calcification and vinegar as a solution

Don't know why, but every time I've had a problem with the holding tanks seeping back into the toilet bowel, I've filled the head with a gallon of vinegar and pumped it half through, then waited overnight, and the problem is gone for weeks/months. Haven't had to replace the oneway rubber valve in years.

For what its worth.

Re: test with vinegar

After I solved the problem with heavy calcification by using the tool shown
in the photo section and described in earlier postings, I decided to conduct
an experiment with vinegar and the calcified deposits.

I took some chunks of the deposits and placed and equal amount in each of 2
jars. One jar was filled with 50:50 salt water and vinegar and the other
with 50:50 drinking water and vinegar.

The reults after 30 days of soaking in the solutions:
Nothing, Nada, Zilch... The vinegar solutions had absolutely no effect.

Possibly the results that some have seen with adding vinegar to the head to
rid calcified deposits is some sort of placebo effect!

Thought you would like to know.

Best,

I had the same problem of backflow into the bowl, replaced the hoses and joker valve but still had backflow into the bowl. I added a valve to the line and shut it off whenever I leave the boat. Interestingly it fills the bowl but never overflows the bowl when the boat's not rocking...I guess there's just enough in the hose to fill the bowl. Seems like the leak has finally quit and I'm not sure I need the valve any more, but I'm still going to close it off when I'm gone.

A marine head service guy told me that vinegar and oil was good for preventative maintenance, but not for clearing out clogged lines. He said some people use muriatic acid. Has anyone done that? Any luck?

HI, When you changed the joker valve did you clean out the 90 deg. elbow of salt? The build up of salt/cake in the elbow will not allow the joker valve to close tight. We use baby oil to keep the hose clear and we us silicon grease on the ID of the elbow for easy cleaning later.. It works for a while but the salt always builds up over time. So every 18 months or so we change the hose. We keep two meters of 1.5 inch hose as a spare all the time... We also ask guess to put their used paper in the trash pale.. if you don't eat it fisrt it does not go in the head.. we buy brown paper lunch bags as trash can liners..
Fairwinds to all. We are now in Annapolis.

Hi Kent,
Yes, muriatic acid is the answer! We pour about a liter in each head evry couple or three weeks. Let it bubble up nice and brown - overnight is best - then just flush it down. We are now 8 years on our hoses and no problemo!
Ciao, Craig

Hi Craig. Hope you two are well and enjoying the eastern Med. I'm "stuck" in Charleston until I can get enough time off to get her on up to the Chesapeake. Charleston's not a bad place to get stuck, tho.

Do you just use muriatic acid as it comes off the shelf or dilute it? What's the final concentration of what you pour into the head?

Thanks and Aloha to Katherine.
