I live in a 3 Story condo. Whenever I run my water in the kitchen, bathrooms or flush my toliets, it is followed by a loud noise in the pipes once the water is turned off. It sounds like pressure or air. I also hear the noise when I am not running water. So, I am guessing it is the result of my neighbor running water.

What is this? Is it pressure or air in the pipes.

See the posting about 90 PSI

Also a lot of installers use what is called band iron for supporting piping instead of Clevis hangers and riser clamps and do not space these supports properly or figure in a four fitting swing for expansion of hot water piping (expansion loops)

Without the proper supports pipes vibrate and in severe conditions hydraulic shock waves occur and then an air chamber should be installed to allow the shock waves to hit the air which then compresses air compresses water doesn't ( much,much lesser degree) so this wave can cause some serious piping damages.

This sudden shock normally occurs with quick closing valves (solenoid) found on dishwashers and washing machines and some ball cocks found in toilets

Thanks for your reply. I think that my problem is a weak valve on my washing machine. How do I correct this?
