5 Handy Steps for Fixing Water Hammer Issues in Your Plumbing

The Perfect Tool to Help Solve Plumbing Water Noises as well as Water Hammer in Home Piping

In some plumbing systems when a faucet or an automated shutoff like in a washing machine stops the water too quickly, it tries to keep going and you obtain a banging vibration throughout the house. The pipelines are in fact shifting as well as impacting something. This banging force can be strong enough to damage pipe joints apart which could trigger real issues.

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


A water hammer issue can occur suddenly, most notably when shutting off a kitchen or washroom tap or any other tap quickly. It basically creates some vibrations through the  pipelines which causes the hammer noises.


These sounds are comparable to shock waves that will make fixtures, pipelines and faucets to vibrate. Technically, this phenomenon is a form of hydraulic shock, caused by higher than normal water pressure within the pipelines.


A water hammer actually is fairly an aggravating issue, but is also one that can bring about damages to the system. The best remedy to fix this problem is by setting up a water hammer/hydraulic shock arrestor. This device can be easily installed in various types of supply lines.

This hydraulic shock effect of water hammers can be the most typical sound problem in a system. When some appliances or faucets quickly shut off the water circulation, it usually takes place.


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

This problem can likewise arise from other appliances or fixtures, such as washing machines as well as dish washers. These cleaning machines usually include solenoid valves which shuts down water circulation really rapidly such that it goes from on to off within a second.


Although these ideas may be of good value, the hammer problem might be more than it might seem. Need this done right the very first time? An emergency plumber will certainly be your best choice to manage this kind of problem.

A Traditional Option for Dealing With A Water Hammer

Older homes usually have water supply lines with pipe installations called chambers. These chambers are located on cold as well as hot water lines near each inlet shutoff or tap.


The chambers are hardly visible, except where the area could be incomplete such as in utility rooms. Or else, the chambers are concealed within walls along other plumbing lines.

Plumber-Basic Components of a Plumbing Fixture

The function of these air chambers are to work as shock absorbers when water streams under high pressure as well as speed. Generally, the air compresses whereas water does not. As such, the air in the chamber is compressed by the water pressure, making the water pressure halt once the tap or appliance switches off the water circulation quickly.


Shock waves from the very pressurized water hit the very pressed air in the chamber instead of hitting the water pipes. The chambers are made as well as mounted on-site prior to the area where the water supply lines get to the faucets is closed off. These chambers usually have a size of around 12 inches or longer, with a comparable diameter size to that of the pipelines.


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


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

How to Utilize Water Hammer/Hydraulic Shock Arrestors

One of the most efficient as well as lasting approach of eliminating the problem of water hammers in water lines is setting up hydraulic shock arrestors on supply lines that make noise.


These arrestors work like air chambers, but they include a covered gas or air-filled chamber. The seal is usually produced by a piston or diaphragm.


The piston or diaphragm will move in the event of a “water hammer” situation, therefore absorbing the shock while making certain the gas or air as well as water are always separated.

Directions for Installation:.

Materials as well as Tools Needed:

Listed here are the basic materials as well as tools needed to install a hydraulic shock absorber:


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


Step 1: Shut off the primary water supply valve.

turn the major water supply or merely the water valve leading to the dishwasher, toilet, or the washing unit by using the valve near the fixture or appliance.


Most appliances come with 2 valves for shutting off the water circulation, one for the cold water line and another for the hot water line. Toilet have usually only one shutoff.


Dish-washing machines usually have one shutoff on the hot water line. Simply switch the water shutoff clockwise until it’s securely closed. Make sure to totally stop the water circulation between the fixture or appliance and the shutoff.

Step 2: Detach the water supply tubes.

Take a towel or pail and place under or around the work area in order to catch all water that might splash. Next, disconnect the hose pipe or tube that supplies water to the fixture, shutoff, or appliance shutoff.


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


Use tongue/groove pliers to loosen tight supply tubes. You can likewise use a wrench (adjustable one) to loosen all tight compression nut that links the tube or pipe to the shutoff.

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

Apply tape to wrap the water inlet or valve male threads (depending upon the area you separated the supply tubing or pipe). You can use 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: Set up 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 installations on the toilet or dishwasher valve, affix the tubing of the arrestor into each compression installation.


Now, slide each compression ring onto the valve and thread the arrestor tubing 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 use a variable pipe wrench to tighten the nut.

Step 5: Reconnect the supply hoses or tubes.

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


You can now purge your toilet or run the dishwasher or washing unit for a cycle to test whether the arrestors are operating properly. Examine the links for any leaks and tighten up all with a wrench or pliers. Get in touch with a professional plumber if you encountered an issue and need assistance.
