What is Water Hammer?


Water hammer is a shockwave of stress that happens within your pipelines when water circulation stops or changes direction quickly. Think of a group of joggers dashing down a narrow hallway, only to have a door slam closed at the end. The unexpected quit causes a domino effect, leading to a crash of bodies. In your plumbing system, water imitates those joggers, and when it's forced to quit suddenly, it produces stress waves that take a trip through the pipes.

The Scientific Research Behind Water Hammer


Water hammer is fundamentally regarding kinetic energy. When water moves with pipelines, it lugs energy. If something disrupts that movement-- like a valve closing as well swiftly-- this momentum transforms right into a pressure surge. Pipelines, installations, and valves experience this spike in pressure, usually resulting in that banging noise you dread.

Typical Root Causes Of Water Hammer


Understanding the root causes of water hammer is the primary step to fixing it.

Abrupt Shutoff Closure


Rapidly turning off a faucet or appliance can develop a sudden water circulation halt. Dishwashers and cleaning equipments, which have automatic valves, are frequently culprits in creating these unexpected quits.

Incorrect Pipe Sizing


Pipelines that are as well small for the quantity of water streaming through them can boost the likelihood of water hammer. Restricted room suggests higher velocity, and greater velocity means stronger pressure rises.

High Water Stress


Too much water pressure not just wastes water and cash however likewise amplifies the effects of water hammer. The more pressure behind the flow, the more challenging it hits when required to stop.

Why is Water Hammer a Problem?


You might ask yourself, "Is water hammer just a sound issue?" It's more than that. While the audio can be frustrating, the real problem exists underneath the surface.

Securing Loose Pipes


Pipes that aren't appropriately safeguarded can intensify water hammer audios. Including pipe straps or cushioning materials can aid maintain them and avoid them from rattling against surfaces.

Making Use Of Air Chambers or Arrestors


Air chambers are basic devices that catch a pocket of air in a vertical pipe. This air acts as a padding, taking in the pressure surge. If you don't have them, installing water hammer arrestors can achieve a comparable effect.

Long-Term Solutions and Upgrades


If you're trying to find more irreversible repairs, it could be time to take into consideration some upgrades.

Setting Up Water Hammer Arrestors


These devices, created specifically to counter water hammer, can be positioned near fixtures or devices. They consist of a piston and chamber that absorb stress adjustments prior to they spread throughout your system.

Including Development Tanks


A growth storage tank attached to your water heater can help alleviate pressure variations brought on by thermal expansion. By offering water a location to go when heated, you lower anxiety on pipelines.

Upgrading Pipe Materials


If you're planning renovations or dealing with an older home, upgrading to even more flexible piping products, like PEX, can help in reducing the danger of water hammer. These materials can soak up shock far better than inflexible pipes.

Do it yourself vs. Expert Help


Some house owners enjoy a great do it yourself difficulty, while others like to leave plumbing concerns to the pros.

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.
