Common Plumbing Problems - Noises

Check to see if any pipes are rubbing against one another or on a rough surface inside the wall or floor. The copper water supply to the dishwasher may be rubbing against a rough surface. Dishwashers have a solenoid valve (and other electronic appliances) that shuts the water off in an instant. The sudden stop is what causes water hammer. Sometimes the noise is generated from water heaters that have energy-saving nipples on top.
