What Is Water Hammer in Plumbing—and How to Fix It
Ever heard a loud banging or clanging from your pipes when you turn a faucet on or off? This is called water hammer. It happens when water flows unevenly, creating a “shockwave” effect.
The sudden change in water direction or speed causes a pressure change. This leads to the loud noise. Knowing why it happens is key to solving it. In this article, we’ll dive into water hammer and how to fix it.
Understanding the Basics of Water Hammer
Exploring water hammer basics shows its causes, symptoms, and when it happens. This sudden noise is common in homes and often points to plumbing problems. Remember it is always best to hire plumbing services in Scottsdale, Arizona if you are unsure of the issue.
What Causes Water Hammer?
Water hammer noise comes from sudden water flow changes. It’s often due to loose pipes, worn-out stop valves, entrapped air, ball-float valves, and fast-acting valves. When these parts don’t work right, they cause the loud banging sound.
Common Symptoms of Water Hammer
Water hammer symptoms are clear. You might hear banging noises when you turn taps on or off. Sometimes, the sound is so loud it surprises you. Spotting these signs is the first step to fixing the problem.
When Does Water Hammer Usually Occur?
Water hammer can happen anytime, but it’s more common with sudden water pressure changes. This can happen when valves are closed quickly or if there’s a plumbing issue. Knowing when it happens helps with water hammer troubleshooting.
By knowing the causes, symptoms, and when it happens, homeowners can start solving the problem. They can find a good water hammer solution.
The Science Behind Water Hammer
To understand water hammer, we need to know the science behind it. It happens when water flow suddenly changes in a plumbing system. This creates a shockwave that can make noise and damage the system.
How Water Pressure Affects Plumbing
Water pressure is key in water hammer. High water pressure makes the problem worse. It increases the force of water hitting valves and fittings.
When a faucet is turned off fast, the water flow stops suddenly. This creates a shockwave that travels through the pipes. It causes the banging or clanging noise we know as water hammer.
High water pressure puts more stress on pipes, fittings, and valves. This makes them more likely to get damaged by water hammer.
The Role of Air Chambers in Water Hammer
Air chambers help reduce water hammer by acting as a cushion. These are vertical pipes filled with air, connected to the water supply lines. When a valve is closed fast, the water stops suddenly, but the air compresses. This absorbs some of the shock, reducing the noise and impact of water hammer.
But, air chambers can lose their effectiveness over time as they fill with water. Regular maintenance, like draining the system, helps keep them working well. This is important for reducing water hammer noise.
| Factor | Effect on Water Hammer | Mitigation Strategy |
|---|---|---|
| Water Pressure | High pressure increases the risk and severity of water hammer. | Regulate water pressure using pressure-reducing valves. |
| Air Chambers | Air chambers can reduce the impact of water hammer by cushioning the shockwave. | Regularly maintain air chambers by ensuring they remain air-filled. |
| Valve Closure Speed | Fast valve closure increases the likelihood of water hammer. | Install valves that close slowly or use devices that slow down the closure. |
Identifying Water Hammer in Your Home
The banging or thumping sounds from your walls or ceilings might be more than a minor issue. It could be water hammer. This problem can damage your plumbing system if not fixed. It’s key to spot its signs and know where the noises come from.

DIY Solutions for Water Hammer
Fixing water hammer doesn’t always need a pro; you can try DIY solutions. These include methods for dampening water hammer.
Two effective DIY solutions are adjusting water pressure and installing water hammer arrestors. These can lessen the noise and damage from water hammer.
Adjusting Water Pressure
One easy way to reduce water hammer is by adjusting your home’s water pressure. High pressure makes the problem worse, so lowering it can lessen the shockwave.
To adjust your water pressure, you might need a pressure-reducing valve. Make sure your plumbing system can handle it and follow the manufacturer’s installation guide.
Installing Water Hammer Arrestors
Water hammer arrestors help dampen water hammer by absorbing the shock. They’re usually put near fixtures that often get water hammer, like washing machines and dishwashers.
These arrestors have springs and air bladders that compress to soak up the water’s movement. This reduces the noise and impact of water hammer.
Professional Solutions for Water Hammer
Severe water hammer problems often need a professional fix. DIY solutions work for small issues, but big ones need a plumber’s skill.
When to Call a Plumber
