just wondering if any of you guys could help me before I consider
calling the plumber.
Basically, when the hot water is turned on and the boiler activated, it
starts to shudder, firstly fairly quietly, but becoming louder and
louder. After about 5 to 10 seconds it reaching a climax, then stops.
If the water is kept running the shuddering starts again after a couple
of minutes. I guessing this maybe something to do with the pressure?
Any suggestions would be greatly appreciated.
