"singing" pipes

[mformark]

The water pressure in my area seems to have increased radically in the last couple of weeks and now my entire plumbing system howls at various point of the day and night. We're talking express train level of noise here!.
Flushing the loo a couple of times in a row stops it, but a few minutes later off it goes again. Any ideas on curing this? The water Co. deny all knowledge of the pressure increase.

I am not a plumber. You could always try fitting a pressure reducing valve
