Below is a brief journey around the pump that is fitted to your central heating system. If at some stage you need to replace this pump and are not confident to remove it from your heating system, then it will definitely pay you to use the services of a professional plumbing company. Kensington Plumbers carry out all types of plumbing work.

The pump does not have may things to go wrong and also not much to see on its casing either, however you will see where the electrical cable enters the motor (this is coming from the boiler). On some pumps, you will also notice that a metal or plastic cylinder is fitted onto the pump. This is a called (smoothing) capacitor and is fitted to prevent the magnetic field generated by the pump motor (as it turns) from causing any interference to any of the domestic electrical equipment such as a television or radio. A Kensington Plumber can fit a pump. There could also be a dial or it may be a screw which is fitted to the casing so that the pump speed can be adjusted manually by you or a professional either by hand or screwdriver. The pump is almost silent as it runs, although it vibrates which you can feel if you touch it. The large screw situated on top of the pump is the bleed screw and is fitted to allow the homeowner or a professional plumber to purge any air that may be inside. No central heating pump is able to prime itself, therefore if air was to leak in, the pump would not be able to get rid of the air until it is bled out manually. This can be done by loosening the screw slightly until the hissing sound stops and then tightening the screw back up again. The pump as you can see is really quite basic, but very important for the job of keeping you warm.
