We have a water pump located next to the immersion heater in the airing cupboard in the upstairs bathroom (see attachment). I assume this is for the central heating system as it leaks when the central heating is switched on. The leak is only a drip but quite a lot of water collects when the heating is on a lot as it is during winter. The leak is a drip from the front and centre of the pump shown in the picture. As you can see there are also scale deposits, which I asume are due to the leak.
I was told by a friend that it is easy to fix, but he was not too clear about how. Can anyone enlighten me? I believe it involves removing the central slotted screw. Thanks in advance.
[quote="plumbbob"]The leak is from the cover over the main pump bearing. If it won't tighten up, remove it (you will get a small drip or dribble of water whilst it is removed) clean it and replace tightly.
It may be the rubber "O" ring is damaged and needs replacing.[/quote]
