What Is Water Hammer?

Water hammer is a plumbing condition that occurs when flowing water suddenly stops or changes direction, creating a pressure shock wave inside the pipes. This pressure wave causes pipes to vibrate, resulting in the loud banging or knocking sounds often heard behind walls or ceilings.

What Causes Water Hammer?

Several plumbing issues can contribute to water hammer.

Sudden Valve Closure

When a faucet, appliance, or plumbing valve closes quickly, the moving water comes to an abrupt stop, creating a pressure wave inside the plumbing system.

Water Momentum

Because water has mass and momentum, stopping its flow suddenly causes it to strike valves and fittings, sending shock waves throughout the pipes.

High Water Pressure

Excessively high water pressure can increase the force of the pressure wave, making water hammer more severe.

Loose Plumbing Pipes

Poorly secured plumbing pipes may move when pressure waves occur, creating louder banging sounds and increasing the risk of damage.

Signs of Water Hammer

Common symptoms include:

• Loud banging or knocking noises.
• Pipes vibrating after faucets are turned off.
• Plumbing noises inside walls.
• Shaking water supply lines.
• Leaking pipe joints.
• Sudden pressure fluctuations.

Why Water Hammer Should Be Repaired

Ignoring water hammer can eventually lead to plumbing damage, including:

• Loose pipe fittings.
• Water leaks.
• Damaged valves.
• Burst pipes.
• Damaged appliances.
• Premature plumbing system wear.

Common Water Hammer Solutions

Several repair methods may be used depending on the cause of the problem.

Water Hammer Arrestors

Water hammer arrestors absorb the pressure shock created when water flow suddenly stops, helping eliminate banging noises and protect the plumbing system.

Pressure Reducing Valves

If excessive water pressure is contributing to the problem, installing or adjusting a pressure reducing valve (PRV) can help stabilize the system.

Secure Loose Pipes

Properly fastening and supporting plumbing pipes helps minimize movement and vibration during pressure changes.

Slow-Closing Valves

Some plumbing fixtures are designed to close gradually, reducing the sudden pressure changes that cause water hammer.

Air Chambers

Air chambers or standpipes can provide additional cushioning by absorbing pressure surges. Older air chambers may require maintenance or replacement over time.
