A good tip in finding what pipes are causing the noise is to note when the noise happens and whats being used e.g are you using the shower? is the washing machine filling? does the noise happen when you turn the heating on?
Then you need to try and locate the noise. listen around the house while someone turns the tap on and off or when the heating has recently been turned on.
Next, what sort of sound are the pipes making?
Creaking Pipes. A creaking sound can be caused by the water in the pipes heating and cooling making the copper expand and contract. One way to solve this problem is insulating the pipes using pipe lagging, this will slow down the rate the pipes heat up and cool down, reducing and even stopping the loud noises.
