[diyplumber1980]

Hi guys, ive got a problem i need help on. When i flush the loo, the pipes around house vibrate very loudly. Its both hot and cold pipes. The toilet has push button flush. The house has a combi boiler only, no water tank. Its a large house, 3 floors, 5 bedrooms. Any help wouls be much appreciated.

Make sure all the pipe work is clipped secure, if you cannot reach all of it say behind cupboards or boxing push some foam insulation on it to avoid any vibrations.
Check your inlet valve on the cistern it may be worn causing pulses reverberating back up the supply pipe.
