Clogged hose ideas

[SEVEN]

My center head pumps plenty of fresh water into the bowl but it will not suck it out. I remote Galley Maid pump and rebuilt it with new stators and re-installed. Same issue. I spoke to Raz and Jim told me I have a clog in the exit line that leads to the holding tank. My original thought was to replace the hose completely which is an all day job. I then thought to try a snake to try to clear. If that fails I was going to pour Muriatic acid into the hose. Has any one tried any of this ideas? If so can you let me know what worked. Or if you have any other thoughts. Thanks in advance.

Have not had the pleasure on this boat. But you said thoughts welcome so I would wait until the last chance with the acid. Snake would be my first shot. Specifically an electrician's snake. Be mentally prepared for the fact that the hose has collapsed internally and no amount of blunt trauma or chemical warfare will save you from replacing it.

I’ll also try the electricians wire puller are well.

I have tried Sew Clean recirculated through the hose with a pump. Worked for a awhile (2-3 months) , then it plugged, maybe from loosening the deposits , so badly that it held 80 psi air pressure. This was truly disappointing. Then a new hose fixed all . First time I changed a long hose , it took me 3 weeks, this included painting the bilge . I cut extra hatches and greatly enlarged others. Now it’s a day or two . Check the hose fitting on the discharge end of the pump. I have had them completely clogged with hard deposits. Oscar’s statement about an internally collapsed hose is is something to take to heart .

Ha, ha! You said a mouthful there. That's every project of mine.

Consider vinegar and a large shop-vac drawing back.
Don't pour any acid down there. It has to come out some way. Hopefully not on you or in your eyes unexpectedly.

It’s either going to be the plumbers snake or replace the hose completely. I’ll start using vinegar as a monthly solution.I plan on working on it Tuesday and Wednesday. I’ll keep everybody apprised as to my findings.

I had same problem, replaced hoses still problem, turned out to be the 90' fittings on top of tank had hard deposit inside reducing diameter to 3/8". Replaced fittings and no issues for 6yrs. Had to use heat to get fitting loose.

I have witnessed this and is a great idea to check into this soon.

I have also witnessed good looking and new stators not pump correctly and clogged priming tubes.
Did this setup work before the pump work or the pump was suspect when the system stopped working?
