Shower drain

[John 32i]

Does anyone have any advice regarding a shower drain on a Beneteau Oceanis, I can hear the pump working but the water remains in the shower tray - I have poked a piece of wire about 6 inches up the pipe but then it wont go any further! Is it possible there is a stuck valve or something somewhere that I havent opened..?

Is there a bundle of hair around the pump impeller?

Is there a Jabsco filter ( eg http://www.force4.co.uk/ProductImages/fullsize/830074.jpg ) somewhere inline between drain and pump? If so it will be blocked. Unscrew the cap and get out all the hair and gunge, also from the inlet to the filter unit.

It may be fairly well hidden - follow the pipe run....

If it is a diaphragm type pump the diaphragm may have been perforated or perished and will need replacing. We had the same problem but despite a filter some other items of debris in it were preventing a proper seal.

Check this

On my Oceanis 323 the bilge pump and the shower pump were one and the same, there was a switch in the shower marked “Shower Pump” and a switch at the navigation control panel marked “Bilge Pump”. They both started and stopped the same pump, but you had to change a two way valve under the wash hand basin to alter the sauce for the pump. If yours is the same, is the valve turned the wrong way ?

I did not like that arrangement, so I have added a separate bilge pump to my boat.
Good luck, George

If the motor is going and there's plenty of water in the drain then I would trace it through undoing each big as it goes.

I started at the seacock end, testing first whether that was open and clear - can you pump water down the last pipe to it? Then can the pump do it, then is the filter clear and can you pump from a bucket outwards and so on.

That has mostly worked for me but on one occasion last year all the connections were clear individually but there the whole system didnt work when connected. I dismantled and cleaned the pump - all looked fine but still no joy. I then found the previous owner must have put the back on the wrong way round so it did pump - but feebly.

Other problems I've found have been blockages, poor electrical connection, blocked and rusted filters and mangled/split pipes leading to bad seals. Oh yes, and a seacock shut after I'd spent hours on a problem.
