After repairing a holed diaphragm and giving the boiler a service it now vibrates.
The vibration starts first thing in the morning when the CH kicks in.
Turning on the hot tap to temporarily stop CH then turning off hot tap cures the problem.
Every thing is fine. The heating goes off mid morning, but then when you run hot water the vibration comes back. When CH comes back on in the evening there is no vibration.
Any ideas would be greatly appreciated.
