It's not simply an irritating peculiarity of older homes-- water hammer can occur anywhere, and if left untreated, it can result in more significant plumbing problems. In this write-up, we'll debunk water hammer, explore its causes, and discuss functional means to repair and avoid it. Consider it as your best overview to taming those unruly pipes once and for all.
What is Water Hammer?
Water hammer is a shockwave of pressure that happens within your pipes when water flow stops or changes direction abruptly. Think of a crowd of runners running down a slim hallway, just to have a door slam closed at the end. The abrupt quit creates a chain reaction, causing an accident of bodies. In your plumbing system, water imitates those runners, and when it's forced to stop all of a sudden, it creates pressure waves that travel with the pipelines.
The Science Behind Water Hammer
Water hammer is essentially regarding kinetic energy. When water moves with pipes, it lugs momentum. If something interferes with that motion-- like a shutoff closing as well quickly-- this momentum changes into a stress rise. Pipes, installations, and shutoffs experience this spike in pressure, often leading to that banging noise you dread.
Typical Sources Of Water Hammer
Comprehending the source of water hammer is the primary step to fixing it.
Unexpected Valve Closure
Swiftly shutting down a faucet or appliance can produce an abrupt water circulation halt. Dishwashers and cleaning equipments, which have automated shutoffs, are commonly perpetrators in producing these unforeseen quits.
Inappropriate Pipe Sizing
Pipes that are too tiny for the quantity of water moving via them can enhance the probability of water hammer. Limited room suggests higher speed, and higher velocity indicates more powerful pressure surges.
High Water Stress
Excessive water pressure not just wastes water and money but additionally magnifies the results of water hammer. The even more force behind the flow, the more difficult it strikes when forced to quit.
Why is Water Hammer a Problem?
You might ask yourself, "Is water hammer simply a sound issue?" It's more than that. While the audio can be frustrating, the genuine trouble lies under the surface area.

Protecting Loosened Pipes
Pipelines that aren't correctly protected can magnify water hammer sounds. Including pipeline straps or supporting materials can assist support them and avoid them from rattling versus surfaces.
Utilizing Air Chambers or Arrestors
Air chambers are basic tools that trap a pocket of air in a vertical pipe. This air works as a pillow, absorbing the stress surge. If you don't have them, setting up water hammer arrestors can attain a comparable impact.
Long-Term Solutions and Upgrades
If you're seeking even more long-term solutions, it might be time to take into consideration some upgrades.
Installing Water Hammer Arrestors
These devices, created especially to respond to water hammer, can be placed near fixtures or appliances. They include a piston and chamber that take in stress adjustments prior to they spread out throughout your system.
Including Development Containers
A development container attached to your hot water heater can assist reduce stress changes triggered by thermal development. By providing water a place to go when heated up, you decrease stress on pipes.
Upgrading Pipe Materials
If you're intending renovations or taking care of an older home, updating to even more adaptable piping materials, like PEX, can help in reducing the risk of water hammer. These products can absorb shock better than inflexible pipes.
Do it yourself vs. Professional Support
Some homeowners love a good DIY difficulty, while others favor to leave pipes issues to the pros.
Determining Your Comfort Level

What Is Water Hammer & How Do You Stop It?
How Water Hammer Is Triggered
Water hammer is often triggered by a valve closing at the end of a pipeline. Tilting disc, swing, and double-door check valves tend to close very quickly, creating high pressure, but water hammer can also be caused by pump failure.
Water is an incompressible liquid, so an impact against a closed valve causes a shock wave that propagates at the speed of sound. It will continue until it hits the next pipe elbow or end of a pipeline.
In homes, water hammer often occurs when a washing machine valve closes after the drum reaches full capacity. Water continues to flow rapidly. It has nowhere to go, so it slams against the side of the pipe, which can bump against other pipes or the frame in the wall.
What Causes Water Hammer?
High water pressure: Excessive pressure can make the issue more pronounced. Quick-closing valves: Appliances like washing machines or dishwashers often have quick-closing valves that create abrupt water flow changes. Loose pipes: Pipes that aren t properly secured can amplify the noise and vibrations. Faulty air chambers: Many plumbing systems include air chambers that absorb shock. If these become waterlogged, they lose effectiveness. How to Stop Water Hammer
Drain the air chamber: Home plumbing systems often have an air chamber to absorb the shock of water when a valve closes. Located inside walls, an air chamber can become waterlogged. This can be fixed by draining your plumbing system, which requires turning off the main water valve and opening the highest faucet in your home. Then drain water from the lowest faucet. The chamber should fill up with air once the water is drained and resolve your water hammer problem. Install a water hammer arrestor: This device has an air-filled cylinder to absorb the impact of abrupt increases in water pressure. Most water hammer arrestors are installed between the shut-off valve and supply line via screw-type connectors. One arrestor should be installed on the hot-water supply line and another on the cold-water supply line. Adjust the water pressure: If the water pressure in your pipes is too high, the steps above will only work temporarily. You can regulate the pressure by adjusting the pressure-reducing valve, which is often located where the main water supply enters your home. To adjust the valve, turn the handle or, if necessary, with a wrench or screwdriver. The setting should be below 50 pounds per square inch (psi). Reducing water pressure also conserves water, saves energy, and can prolong the life of plumbing appliances. Tighten your water supply lines: Sometimes, the U-shaped straps to fasten water pipes to wooden joists or studs aren t tight enough. As a result, pipes can shift and cause noise. You can fix the problem by tightening the screws holding loose pipe straps. Additional straps can be added to improve stability. Pipe straps are usually made of thin metal or plastic, while padded types are available to reduce vibration. Insulate water supply lines: Foam pipe insulation prevents pipes from freezing and can create a cushion for loose pipes. They fit easily over your water supply line and can usually be purchased in 6-foot lengths. Effect of Water Hammer on Plumbing Systems
Water hammer may happen occasionally, but it can cause a sudden plumbing failure or lead to damage over time. It may occur due to excess water pressure in supply lines, or perhaps plumbing pipes have come loose.
Pumps, valves, expansion joints, gasketed joints, and welded joints can be seriously damaged, as can various fittings and connections. Water leaks, ruptured pipes, and property damage can result.
