5 Useful Steps for Repairing Water Hammer Problems in Your Plumbing

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

In some plumbing systems when a faucet or an automatic valve like in a washing machine ends the water too quick, it attempts to keep going and you get a banging sound throughout the house. The pipelines are in fact shifting and also hitting 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 addressed by putting a unique air chamber device (shock arrestor) on the affected valve. This process gives the water someplace to go due to the fact that the air is compressible.


A water hammer issue can occur unexpectedly, mainly when shutting down a kitchen or bathroom tap or any other tap quickly. It basically creates some vibrations via the  pipelines which causes the hammer noises.


These vibrations are comparable to shock waves that will make fixtures, pipelines and faucets to shake. Technically, this phenomenon is a kind of hydraulic shock, caused by higher than normal water force within the pipelines.


A water hammer actually is quite an bothersome issue, but is also one that can lead to problems to the system. Nevertheless, the most ideal option to repair this issue is by installing a water hammer/hydraulic shock arrestor. This device can be easily mounted in different types of supply lines.

This hydraulic shock impact of water hammers can be the most usual sound issue in a system. When some home appliances or faucets quickly close off the water circulation, it generally occurs.


The speed at which water circulation is stopped is what causes those shock-waves which makes the supply lines bang against each other and framing members such as floor joints and also wall surface studs or on each other.

This issue can also arise from other home appliances or fixtures, such as dish-washing machines and also washing machines. These cleaning units generally feature solenoid shutoffs which turns off water circulation very fast such that it goes from on off within a second.


Although these suggestions may be of excellent value, the hammer issue may be more than it may appear. Need this done right the first time? An emergency plumber will certainly be your ideal choice to handle this kind of issue.

A Typical Solution for Repairing A Water Hammer

Older homes generally have water supply lines with pipeline fittings known as chambers. These chambers are located on cold and also hot water lines near each inlet valve or tap.


The chambers are barely noticeable, other than where the area might be unfinished such as in laundry room. Otherwise, the chambers are concealed within walls along other plumbing lines.

Plumber-Basic Components of a Plumbing Fixture

When water flows under high force and also speed, the function of these air chambers are to act as shock absorbers. Generally, the air compresses whereas water doesn’t. The air in the chamber is pressed by the water force, making the water force halt once the tap or appliance turns off the water circulation quickly.


Shock waves from the very pressurized water hit the very pressed air in the chamber rather than hitting the water pipes. In most cases, the chambers are fabricated and also mounted on-site before the area where the water supply lines get to the faucets is closed off. These chambers generally have a size of around 12 inches or longer, with a comparable diameter size to that of the pipelines.


Nevertheless, if makeshift chambers get full of water with time, the air that works as the shock absorber gets eliminated. It’s possible to recharge these chambers that have become filled with water by simply switching off the water supply of the affected pipelines and then draining any water from the pipes. By doing so, the air is allowed to flow back again right into the chamber to load it up again.


When 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 mount water hammer/hydraulic shock arrestors near each tap.

How to Use Water Hammer/Hydraulic Shock Arrestors

The most effective and also long-lasting technique of eliminating the issue of water hammers in water lines is installing hydraulic shock arrestors on supply lines that bang.


These arrestors work like air chambers, but they feature a closed gas or air-filled chamber. The seal is generally developed by a piston or diaphragm.


The piston or diaphragm will move in the event of a “water hammer” situation, therefore soaking up the shock while guaranteeing the gas or air and also water are always separated.

Guidelines for Setup:.

Products and also Equipment Needed:

Listed here are the basic tools and also supplies needed to mount a hydraulic shock absorber:


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


Step 1: Turn off the primary water system valve.

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


Many appliances featured 2 shutoffs for shutting down the water circulation, one for the cold water line and another for the warm water line. Toilet have generally only one valve.


Dishwashers generally have one valve on the hot water line. Just turn the water valve clockwise until it’s tightly closed. Make sure to totally stop the water circulation between the fixture or appliance and the valve.

Step 2: Detach the water system tubes.

Take a towel or bucket and put under or around the work area in order to capture any water that may splash. Next, disconnect the hose or tube that supplies water to the fixture, appliance, or shutoff valve.


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


Make use of tongue/groove pliers to loosen up tight supply tubes. You can also use a wrench (variable one) to loosen up any tight compression nut that attaches the tube or hose pipe to the valve.

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

Use tape to cover the water inlet or valve male threads (depending on the spot you separated the supply tubes or hose pipe). You can use thread-seal or Teflon tape known as plumber’s tape. Wrap it clockwise around the threads for three to 4 times as well as the arrestor’s male threads the exact same way.

Step 4: Install the hydraulic shock arrestors.

Take the arrestor and thread it onto the inlet or valve while rotating 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 right into each compression installation.


Now, slide each compression ring onto the valve and thread the arrestor tubes right into the fitting while sliding 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 use a variable pipe wrench to tighten the nut.

Step 5: Reconnect the supply hoses or tubes.

Connect each water supply hose or tube to every arrestor by using the tongue/groove pliers or a variable pipe wrench to tighten them. You can at this time turn on water circulation from where you switched it off, be it from the primary valve or the valve near the appliance. Switch the valve on until it’s totally open.


You can flush your toilet or run the dish washer or cleaning unit for a cycle to test whether the arrestors are working properly. If you encountered an issue and need help, get in touch with a professional plumber.
