What is the loud banging noise when I turn the water on or off?
A. This is a common occurrence in plumbing supply lines when faucets are opened or closed quickly. You can usually eliminate the problem by securely anchoring those lines, although on long pipe runs, it may be necessary to have a professional technician install air chambers at the end of the run. If you are remodeling or buying a new home, it is best to install piping of the proper dimension along with hammer arresters.
