Water pipes banging when taps are turned on/off


Hi,
I live in a 1970's house. The problem above started happening about 2 weeks ago. I affects both the hot and cold water taps throughout the house, and the banging seems to be localised to some pipes above the lounge.
Any suggestions as to the cause/cure?
Thanks, Simon Mc.

Usually an air lock. We lived in a house that had this problem if ever we left the place for 24hrs it would get back at us by banging the pipes - never did totally fix it, but the old trick of connecting a hose to from the cold to the hot tap down stairs and turn on both usually did the trick.... I also got drenched once or twice so make sure the hose is firmly on the cold tape especially!!

Sometimes there's a run of pipe which is either horizontal or actually uphill. This can get air trapped in it. Either re-route the pipe so that the flow is always downhill, or put an escape pipe at the highest point of the bad routing leading it up higher than the tank to vent the air.
This assumes the problem is caused by air - which it might not be. It's odd that both H&C are affected together.
