The single most common cause of water hammer in residential plumbing is the sudden closure of fast-acting solenoid valves or ceramic disc faucets (such as those found in modern washing machines, dishwashers, and single-handle mixing valves). When a high-velocity stream of water rushing through pipes is halted instantly by a closing valve, the kinetic energy of the moving water creates a powerful hydraulic shock wave that reverberates backward through the piping network, causing violent banging. Verification: Install dedicated water hammer arrestors near these fast-closing appliances to absorb the shock.
