The Scientific Research Behind Water Hammer
Water hammer is basically regarding kinetic energy. When water moves through pipes, it carries energy. If something interferes with that motion-- like a valve closing as well quickly-- this energy transforms right into a pressure rise. Pipes, installations, and shutoffs experience this spike in stress, usually leading to that banging sound you dread.
Typical Causes of Water Hammer

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.
