5 Useful Steps for Fixing Water Hammer Problems in Your Plumbing

The Perfect Device to Help Solve Plumbing Water Noises and also Water Hammer in Home Piping

In some plumbing systems when a faucet or an automatic shutoff like in a washing machine stops the water too fast, it tries to keep going and you get a banging noise throughout your house. The pipelines are actually moving and also banging into something. This banging force can be strong enough to break pipeline joints apart which could trigger real problems.

This phenomenon is known as a “Water Hammer” which can be resolved by placing a special air chamber device (shock arrestor) on the affected valve. This process gives the water somewhere to go due to the fact that the air is compressible.


A water hammer problem can happen all of a sudden, especially when shutting down a kitchen or shower room tap or any other faucet quickly. It basically creates some vibrations through the  pipelines which causes the hammer noises.


These vibrations are comparable to shock waves that will make fixtures, pipelines and taps to vibrate. Technically, this event is a kind of hydraulic shock, caused by high water pressure within the pipelines.


A water hammer actually is fairly an irritating issue, but is also one that can result in damages to the system. However, the most effective remedy to fix this problem is by mounting a water hammer/hydraulic shock arrestor. This device can be easily installed in different types of supply lines.

This hydraulic shock impact of water hammers can be the most common sound issue in a system. It typically takes place when some home appliances or taps quickly shut down the water flow.


The rate of speed at which water flow is stopped is what leads to those shock-waves which makes the supply lines bang against each other and mounting members such as flooring joints and also wall surface studs or on each other.

This issue can additionally arise from other home appliances or fixtures, such as dish washers and also washing machines. These washing machines typically come with solenoid valves which shuts off water flow very quickly such that it goes from on to off within a second.


These tips may be of good value, the hammer issue might be even more than it might appear. Need this done right the first time? An emergency plumber will be your ideal option to handle this kind of issue.

A Traditional Resolution for Taking Care Of A Water Hammer

Older properties typically have water supply lines with pipeline fittings referred to as chambers. These chambers are located on hot and also cold water lines near each inlet shutoff or faucet.


The chambers are hardly visible, other than where the room could be incomplete such as in laundry room. Otherwise, the chambers are hidden within walls along various other plumbing lines.

Plumber-Basic Components of a Plumbing Fixture

When water streams under high pressure and also rate of speed, the function of these air chambers are to act as shock absorbers. Generally, the air compresses whereas water does not. The air in the chamber is compressed by the water pressure, making the water pressure halt once the faucet or home appliance switches off the water flow quickly.


Shock waves from the extremely pressurized water hit the extremely compressed air in the chamber instead of hitting the water pipes. In most cases, the chambers are made and also mounted on-site prior to the section where the water supply lines reach the taps is closed off. These chambers typically have a size of around 12 inches or longer, with a comparable diameter size to that of the pipelines.


However, if makeshift chambers get loaded with water with time, the air that functions as the shock absorber gets eliminated. It’s possible to charge these chambers that have become loaded with water by just switching off the water supply of the affected pipelines and then draining any water from the pipelines. By doing so, the air is allowed to flow back again into the chamber to load it up again.


As soon as the water gets switched on, the air is then caught in the chamber. If this method fails and does not work, then, it will best to install water hammer/hydraulic shock arrestors near each faucet.

How to Use Water Hammer/Hydraulic Shock Arrestors

The most long-term and also effective approach of removing the issue of water hammers in water lines is mounting hydraulic shock arrestors on supply lines that make sounds.


These arrestors work like air chambers, but they come with a sealed gas or air-filled chamber. The seal is typically created by a piston or diaphragm.


The piston or diaphragm will move in the event of a “water hammer” situation, therefore taking in the shock while making sure the gas or air and also water are always divided.

Instructions for Installation:.

Materials and also Tools Needed:

Listed here are the basic products and also devices needed to install a hydraulic shock absorber:


  • Towel or pail
  • An adjustable wrench or tongue/groove pliers
  • Water hammer/hydraulic shock arrestors (their number should be as needed).
  • Plumber’s tape.


Step 1: Shut down the main water supply valve.

Shut the primary water supply or just the water valve leading to the dish washer, toilet, or the washing unit by using the valve near the fixture or home appliance.


A lot of appliances come with 2 valves for shutting down the water flow, one for the cold water line and another for the hot water line. Toilet have typically only one shutoff.


Dish-washing machines typically have one shutoff on the hot water line. Simply turn the water shutoff clockwise until it’s firmly closed. Make sure to totally stop the water flow between the fixture or home appliance and the shutoff.

Step 2: Disconnect the water supply tubes.

Take a towel or pail and put under or around the work area in order to catch any water that might spill. Now, detach the hose or tube that supplies water to the shutoff, fixture, or home appliance shutoff.


The arrestors should be mounted onto either the inlet of the fixture or on the valve or the home appliance outlet. It’s ideal to mount the arrestor closest to the fixture or home appliance.


Make use of tongue/groove pliers to loosen tight supply tubes. You can additionally make use of a wrench (adjustable one) to loosen any tight compression nut that links the tube or tube to the shutoff.

Step 3: Wrap the water inlet or valve male threads with plumber’s tape.

Use tape to wrap the water inlet or valve male threads (depending upon the spot you detached the supply tubes or tube). You can make use of thread-seal or Teflon tape known as plumber’s tape. Wrap it clockwise around the threads for 3 to 4 times as well as the arrestor’s male threads the very same way.

Step 4: Install the hydraulic shock arrestors.

Take the arrestor and thread it onto the inlet or valve while revolving the female fixture or fitting clockwise until it’s hand-tight. In case you’re dealing with compression fittings on the toilet or dish washer valve, affix the tubes of the arrestor into each compression installation.


Now, slide each compression ring onto the valve and thread the arrestor tubes into the fitting while gliding the ring onto the valve. Next, thread the arrestor onto the compression installation’s nut by utilizing the  tongue/groove pliers to tighten the arrestor onto the fitting, then make use of an adjustable monkey wrench to tighten the nut.

Step 5: Reconnect the supply hoses or tubes.

Link each water supply hose or tube to every arrestor by using the tongue/groove pliers or an adjustable monkey wrench to tighten them. You can now switch on water flow where you switched it off, be it from the primary shutoff or the valve near the appliance. Turn the shutoff on until it’s totally open.


You can now flush your toilet or run the dish washer or washing unit for a cycle to test whether the arrestors are functioning properly. Examine the links for any leaks and tighten up any with a wrench or pliers. Speak to a professional plumber if you encountered an problem and need help.
