dab radiator water pumpi have a dab water pump which pumps the water round my radiators from my stove, although it seems to be working fine , it is making a sqeeking noise, is there some sort of maintenance , such as an oiling ppoint on the pump that i should be maintaining, or do you think its maybe an early sign of coming to the end of its life,

There should be a large screw on the top, centre of the pump, slowly loosen to release the air that has been trapped in the pump causing the sqealing. Works 99% of the time.

The pump is water lubricated at the end bearing, so it is very important that it in sitting Horizontal and that there is no air in the end bearing as above.

the pump is horizontal, but the big screw is on the side not the top, i tried undoing it and a bit of water came out, seems to have quietened it a bit

On some pumps the screw just loosens and you don't get much water out.
Just a few drips, but it is enough to do the job.
They are usually quite hard to do as well
