Job today involves unblocking a Jabsco manual bog that has not been used for about a year so i imagine it will stink.What tools and cleaning stuff should i take.Is it right not to use domestos or similar in it?
 
Yuck

Good luck

I will be with you in spirit as I am removing mine which I am expecting to be similarly unpleasant! No bleach - for the little rubber valves.
 
If it really has been unused for a year there is every chance that all bacterial activity will have taken place and it won't smell at all. Strong bleach can damage plastic and rubber if left in contact for a long time but for typical dilute use it will not do any damage. I use a disinfectant sometimes but mostly a rinse through by pumping it (assuming the boat is in the water) should be enough.
 
Single,

From your last post it seems you think the Jabsco is not the problem.

You imply a blocked discharge pipe is the cause.

The seacock does not need to be closed to remove the Jabsco providing there is a high loop in the discharge pipe. And if the discharge pipe is blocked then there shoud be no inward flow of water anyway.

If you suspect solids have been left in the pipe and gone hard you could try rodding the pipe but in my experience this rarely works. I think you are stuck with replacing the pipe and, of course, the seacock.
 
Causeway,

A well meaning response but may be impractical as many boats have a discharge pipe many feet long. Mine for example is about 9 feet from pump to seacock, and the blockage could be anywhere along the length.

We had same problem this year while away for a couple of weeks , I had fitted a new jabsco loo over last winter but as the pipe was 4 mtrs long and behind everything I didn't check the pipe , this was a mistake , within a couple of days it became obvious that there was a issue with flushing , water would come in easily but a huge pressure was felt when trying to pump out .
Not being brave enough to pull the pipe off seacock whilst afloat I dried out against a wall and set about finding the problem , I pulled the pipe off seacock and found this was clear , shining a torch up the pipe revealed that there was a blockage 6 inches back from seacock , not wanting to muck about further I bought a new pipe and fitted that , it did take me a couple of hrs start to finish but worth it to have a loo that flushes .

The most common thing that was said to me at the time was don't put anything down it unless its been eaten first and this is now our rule too .

Agreed. It's a golden rule. Soft toilet paper in small quantity may be OK but "wet wipes" are usually the worst culprits causing a blockage.
 
I'm with Oldsalt on this one: nothing in the loo that hasn't been eaten first is my motto!
Jokes aside, I've used what we call a screwbedoo- sort of like a curtain-spring with a vicious pair of hooks on the end made of bent wire...
Trying to service a loo in situ is at best unpleasant: I'd disinfect the hell out of whatever's left in the system with prolonged contact with dilute oxidising agent (think bleach, but in tiny dilutions). Then close off both seacocks and remove the pump assembly, and don't even try and service the seals- just replace them all. While you're at it, I'd look at your hoses, especially if they're clogged: maybe whipping them off and rreplacing them isn't a bad investment either?
 
As others have said, no problem removing the pump to service providing their is a high loop in the discharge pipe. I wouldn't rush to buy a service kit either. Normal service is often resumed with a good clean. Give the joker valve a good look over as these do become weak and enable the bowl to refill from the loop after emptying.

I would be VERY carefull pulling, pushing or poking at the discharge pipe if it is the usual cheap white stuff of a certain age. When I replaced mine last winter the old pipe ruptured in several places with suprisingly little force.
 
Close both throughulls, replace the Joker valve, don't bother cleaning it they go soft. Then take off the outlet pipe and smack it hard on the ground to get the calcium build up out. Usually there is also a build up at the top of the throughull which you will see, so clean that too.

As said never put anything down the toilet you haven't eaten.
 
face mask and vic up the nostrils, plenty of kitchen towel to contain the liquid that will inevitably flow out once you start undoing a few screws ;)

I tried using the seal kit on an old toilet and ended up buying the whole pump which I should have done in the first place.

Good luck.

I did buy a new pump when the old one became very stiff. After replacing the pump, I had a close look at the old one. In the end, all that was needed was a smear of vaseline round the o-ring of the piston.
I now have two pumps, both working smoothly.

When a Jabsco pump gets stiff, just add a teaspoon of veg oil/olive oil to the pan and flush....
