Hi all
We get a really annoying tapping noise in the central heating pipes when the central heating kicks in. The tapping is very frequent at first (5-10/second) but gradually slows down until it disappears.
As we have a Megaflo system I have read that the problem might be due to overpressurising the central heating. The pressure gauge only show about 1.7bar at the moment.
Therefore, my questions are:
1) Is it possible to reduce the pressure on the central heating only so that the taps are still at high pressure?
2) How do I reduce the pressure on the Megaflo system? I know how to put the pressure up, but not down
3) Could it be some problem other than an overpressured system?
Many thanks for any help you can give.
