If you've ever been in your kitchen and heard a loud banging or rattling sound coming from your sink, you may have experienced an air hammer. This common plumbing issue can be annoying and concerning, but luckily, it's usually an easy fix. In this article, we'll discuss what an air hammer is, why it happens, and how to fix it.Air hammer: What is it and How to Fix It
The kitchen sink is often the source of an air hammer sound. This is because the sink is connected to a complex network of pipes and plumbing systems that allow water to flow in and out. When there is a sudden change in water pressure, such as turning off a faucet or a dishwasher cycle ending, it can create a shockwave that travels through the pipes and causes the loud noise.Kitchen Sink: The Culprit of the Air Hammer Sound
An air hammer is not a standalone problem; it is a symptom of an underlying plumbing issue. The most common cause of an air hammer is water hammer, which is when water suddenly stops or changes direction in a pipe, causing a shockwave. This can happen due to high water pressure, improperly secured pipes, or a malfunctioning water valve. Another potential cause is a lack of air chambers, which are devices that help absorb the shock of water pressure changes.Plumbing Problems: The Root of the Issue
Water hammer is a common plumbing problem that can cause noisy pipes and an air hammer sound. It occurs when water flow is suddenly stopped or redirected, causing a shockwave that travels through the pipes and creates a loud banging or rattling noise. This can happen when a faucet or appliance is turned off, or when a valve suddenly closes. If left untreated, water hammer can put stress on your plumbing system and eventually cause damage.Water Hammer: The Cause of Noisy Pipes
One of the main causes of water hammer and, in turn, an air hammer sound is high water pressure. When the water pressure in your pipes is too high, it can create a greater force when water flow is suddenly stopped or changed, resulting in a loud noise. You can test your water pressure with a pressure gauge, and if it is above 55 psi, you may need to install a pressure regulator to reduce the pressure and prevent water hammer.Water Pressure: The Culprit of Water Hammer
As mentioned earlier, turning off a faucet can be a trigger for an air hammer sound. This is because when the water flow is suddenly stopped, the shockwave travels through the pipes and creates the loud noise. To prevent this, you can try turning off your faucet slowly to see if that reduces the noise. If not, you may need to address the underlying plumbing issue causing the air hammer.Faucet: A Common Trigger for an Air Hammer
In addition to the loud banging or rattling sound, you may also notice your pipes vibrating when you experience an air hammer. This is caused by the shockwave traveling through the pipes and can be an indication of high water pressure or a lack of air chambers. If you see your pipes visibly vibrating, it's important to address the issue before it leads to further damage.Pipe Vibrations: Another Sign of an Air Hammer
As mentioned earlier, air chambers are devices that help absorb the shock of water pressure changes and prevent an air hammer. If your plumbing system does not have air chambers, you can install them yourself or hire a professional plumber to do so. This relatively simple solution can save you from experiencing an annoying and potentially damaging air hammer sound.Air Chamber: The Solution to an Air Hammer
When it comes down to it, the key to fixing an air hammer is addressing the underlying plumbing issue. Whether it's high water pressure, a lack of air chambers, or something else, fixing the root cause will eliminate the air hammer sound. If you're not comfortable tackling this issue yourself, it's best to hire a professional plumber to ensure the problem is resolved correctly.Water Flow: The Key to Fixing an Air Hammer
