Jabsco manual toilet and pipework clean out ?

[Outwith Jack]

Hi all......
Any advice welcome. I have a 1984 river cruiser with 2 toilets. Both manual .
One needs replacing and the other needs new gaskets. But both are very hard to pump out.
I believe the waste pipes have years of build up.
Without replacing the pipes, what product can I run through the toilet and waste pipes to try and break down any crud...... Thanks

Replacing the pipe is the way to go.
But you could try a "pig" on a wire and simply pull it through repeatedly getting bigger each pass.
Horrible, awful, terrible work.
Just replace the piping.

I sincerely hope the pipe runs are short and accessible.Begin by getting the holding tank pumped out then put most of a bottle of pine disinfectant down both of them.It won't make much difference in terms of functionality but it will make the stench a tiny bit less bad.Open all hatches throughout the boat and make sure you have several pairs of rubber gloves on hand.You may be able to detach the blocked pipes and put them in a bucket (a big bucket so both ends stay contained) at which point a strong flow from a hose might dislodge the nastiness once you get to a suitable place to perform such vile deeds.If you need to escalate to a pressure washer,make sure you are wearing waterproofs and a visor and stand upwind but in all honesty removing the old pipes and replacing is a much better idea.

Are they pipes or hoses?

I believe they are original hoses but can't be certain of the age

The green hose does not look like a sanitary hose, they are usually white. The clear hose attached to the green is definitely not a sanitary hose. The white hose has a life span, after which it starts smelling. If possible, use PVC drain pipe on as many runs as possible, and connect the ends with hose. PVC will not permeate smells.
