Fix noisy central heating pipes easily by following this simple ‘how to’ guide. Clanking and clunking noises coming from your heating system is enough to make a person very annoyed. The thought of calling in and paying a considerable amount of money to a plumber to do the necessary work to stop the noises is even more disturbing. Many home repairs and fixes can be done yourself with easily attainable items and at a considerable savings.
Turn off the main controls for your heating system and wait for it to cool completely. The main controls are where you installed your heating system, which is sometimes in the basement. If the heating hasn't been used recently, you may be able to get started right away.
Wad up a rag and hold it in one hand so it is directly below the air-bleed valve. The metal valve can be located on the top of the radiator on either the left or right side.
Insert the radiator key into the air-bleed socket around the valve and very slowly turn it counterclockwise to release the valve pressure.
Let all the air hiss out of the system and quickly turn the valve clockwise as soon as water starts to drip out onto the rag. Make sure the valve is very tightly closed.
Wipe away with a cloth any water that the rag didn't catch and bleed the air out of any of the other radiators on the system in the same way. Turn the system back on when you are finished bleeding.
