Understanding and Fixing the Banging Sound From Pipes

Hearing a sudden, startling bang within the walls after closing a tap can be an unsettling experience for any homeowner. While these noises are often dismissed as simple plumbing quirks or the nature of an old home, they can indicate a water hammer issue in the plumbing system that requires professional attention. This guide to water hammer explains what it is, why it occurs, its risks, and how it may be fixed.

What Is Water Hammer and Why Does It Happen?

sounds The jarring, banging sound often heard after a faucet is closed or when a water-using appliance stops its fill cycle is a sign of water hammer, or hydraulic shock. It is essentially a pressure surge that occurs when the momentum of water flowing through the pipes is suddenly forced to stop or change direction. Its kinetic energy transforms into a powerful shock wave that travels backward through the piping, causing the pipes to vibrate and even strike the home’s wooden framing and structural supports, resulting in loud banging noises.

Several factors can contribute to water hammer, such as:

Quick-Closing Valves: Modern appliances that use water, such as dishwashers and washing machines, can use solenoid valves that snap shut instantly, causing pressure surges.
Loose Pipes: When piping is not properly secured, it has more freedom to move. This lack of stability intensifies the noise and physical impact during a surge.
High Water Pressure: If the home’s water pressure is too high, the kinetic energy of the moving water is increased, making the resulting shock waves much more forceful.
Clogged Air Chambers: When vertical pipe sections designed to act as cushions become waterlogged or clogged, they lose their ability to absorb impact.

The Risks of Ignoring Water Hammer

leak While the noise itself is a nuisance, the true danger of water hammer lies in the repetitive physical stress placed on the pipes. Each occurrence of hydraulic shock subjects joints, fittings, and pipe supports to immense strain. If left unaddressed, this constant stress can lead to leaks or even catastrophic burst pipes.

The high-pressure waves can also disrupt and damage the sensitive internal valves and components of expensive water-using appliances, including dishwashers and washing machines, leading to premature failure. Also, any water leak or burst pipe resulting from unresolved pressure surges can cause extensive, costly water damage throughout the home and a spike in water costs.

Common Fixes for Water Hammer

The most effective way to resolve water hammer or hydraulic shock issues is to consult a professional. A plumber has the specialized tools and expertise to accurately identify the causes of the pressure surge and recommend the best solution.

Potential fixes may include:

Installing Water Hammer Arrestors: These specialized devices contain a spring-loaded piston or a sealed, pressurized air chamber. Water hammer arrestors act as shock absorbers, safely dissipating the energy of the surge before it can cause vibration or damage to the pipes.
Adjusting Water Pressure: A plumbing technician can check the home’s water pressure and, if necessary, adjust it to a safer level for the piping.
Replacing the Water Pressure Regulator: If the existing water pressure regulator is broken or malfunctioning, it can be replaced.
Securing the Pipes: Securing loose pipes can significantly reduce noise and physical wear and tear caused by pipe movement.
