Need some advice from you clever people.
Two days before christmas our water system developed a hammering sound but it intermitent if we fill the bath and flush toilet at same time or bath/washing machine it starts, but not every time it's got to the point were affraid to use water late at night.
Have been told different things from a tap washer to the rising main.
Can anyone help? don't want to get a pro in as I keep spending my money on me Duke's.
Thanks AGE.
