Hello. We recently had a new combi boiler put in, and everything is fine so far. Except every now and then the pipe work in the bathroom (so bath room Rad and waste pipe that goes down through kitchen ) start vibrating a hell of a lot and make a huge racket. This pipeworkl wasnt touched in the boiler switch except to flush the Rad. The first time i had a ook at it the Rad thermostat was on full and tight, so I turned it downa bit and the vibrating stopped - but teh a few days later it started again.
Has anyoen got a clue what could be causing this please?
Thanks
