My bilge was full of water this evening. It appears the bilge pump is misbehaving. I eventually got it to work - basically it didn't seem to be sucking up any water unless it was in a specific position. I am guessing it is on its way out.
So I should replace that pretty soon but in the meantime I'll make regular periodic checks in the bilge. The bilge pump is not fixed down - should it be secured properly or is it supposed to be able to move around? I think the connecting hose is not airtight either and so probably isn't able to suck up water from the bilge as well as it perhaps should.
Any advice on bilge pump positioning would be appreciated! And any replacement bilge pump recommendations would be great as well.
Thanks!

Our pump is sat in a little well bolted to some sheet steel to keep it there. The pipe is after the pump so will wont affect our pump.
Of course a big hole in the oipe will mean its pumping water back into the bridge.

Might just be blocked. Usually they have a removable bit at the base which acts as a strainer.
Have you had a look at it ?

Rule are the dogs danglies.
No real advantage fixing it hard in position - having gravity do the work means it's easier to lift it and clear any debris from the pump inlet.
Best set up is a float switch wired in parallel to a manual switch, that or a fully automatic job if funds stretch - a good battery and a decent pump will shift a fair bit of wet stuff.

I wondered when he talked of a pipe and sucking water up from the bilge.
so wondered if it was a standard bilge pump or something odd

Depends where the water is coming from. If it is coming from above the boat then a float switched pump is okay but if it is coming from below the boat I would prefer to install a timer system to avoid the sinking caused by the float switch failure.
I would guess that in the OP case its a stern tube which needs repacking and/or greasing.

Like ours but with a weight at the bottom When we got it there was a lot of rust that had fallen from above in there. It was a thick orange sludge. A quick strip down and clean and it was as good as new |

Our bilge pump isn’t fixed down, it just sits under the stern gland, held down by gravity, the outlet pipe and wires. Here’s tip, don’t drill holes for screws under where the pump sits! |

Whale gulper. Good pumps not impossible someone has used one as a bilge pump.

My bilge was full of water this evening. It appears the bilge pump is misbehaving. Worth pointing out that if you bilge is full of water (assuming you mean the bilge behind the engine) that this is not technically a bilge pump problem. The pump is there to deal with unexpected water. If unexpected water is getting there then there must be a reason for it. |

Here’s tip, don’t drill holes for screws under where the pump sits!Know of a Princess that took on a lot of water after a minor grounding incident.Later investigation showed that the bilge pump was attached to a wooden pad screwed directly to the skin of the bilge with screws that went right through !!! When they bounced on a hard sand bank, the screws were pushed back through the GRP .... and damn near sunk the boat  dammit I see the forum format playing up again |
