Knocking Sounds in Water Pipes in Liverpool

 Have you ever heard an unexpected knocking or banging sound coming from your water pipes? This is a common issue for many homeowners, and it can be pretty jarring when it occurs. While it may seem like a small inconvenience, repeated knocking sounds inside your pipes could signal a deeper plumbing problem that requires attention.

What Causes Knocking in Water Pipes?

The knocking or banging noise you’re hearing is usually called "water hammer." This phenomenon happens when the flow of water is suddenly stopped or changed direction. This abrupt change creates a shockwave that causes the pipes to vibrate, producing the distinctive knocking sound. Water hammer can occur when you turn off a faucet, flush a toilet, or when appliances like dishwashers or washing machines abruptly stop the flow of water.

Water Hammer: The Primary Cause

Water hammer happens when the water flow in the pipes is abruptly halted, often because a valve closes too quickly. This sudden stop leads to a pressure buildup in the pipes, which generates that familiar knocking noise. 

Air Chambers and Their Function

In certain plumbing systems, air chambers are installed to help absorb the impact of water hammer and reduce the associated noise. These air chambers are small sections of pipe filled with air that act as buffers when water flow is abruptly stopped. However, over time, these air chambers can become filled with water, causing them to lose their effectiveness. When this occurs, the knocking sounds return, and water hammer may intensify. Flushing out the air chambers or replacing them can often resolve the issue and restore peace to your plumbing system.

High Water Pressure

Additionally, high pressure can put unnecessary stress on pipes, fixtures, and appliances, leading to potential leaks and damage. If you're hearing knocking sounds along with other signs of high water pressure, such as sputtering faucets or malfunctioning appliances, it may be a good idea to have your water pressure tested.
