5 Practical Steps for Repairing Water Hammer Issues in Your Plumbing

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

In some plumbing systems when a tap or an automatic valve like in a washing machine stops the water too quick, it tries to keep going and you obtain a banging sound throughout the house. The pipelines are actually shifting as well as hitting something. This banging force can be strong enough to break pipeline joints apart which could cause real problems.

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


A water hammer issue can take place all of a sudden, even more so when shutting down a kitchen or washroom faucet or any other tap very quickly. It basically produces 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 event is a type of hydraulic shock, caused by too much water pressure within the pipelines.


A water hammer actually is rather an irritating issue, but is also one that can bring about damages to the system. However, the most effective remedy to fix this issue is by installing a water hammer/hydraulic shock arrestor. This device can be easily mounted in various types of supply lines.

This hydraulic shock effect of water hammers can be the most usual sound issue in a system. When some home appliances or faucets very quickly shut off the water circulation, it typically happens.


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

This issue can additionally arise from other home appliances or fixtures, such as washing machines as well as dish washers. These cleaning machines typically include solenoid shutoffs which turns off water circulation really rapidly such that it goes from on off within a second.


Although these suggestions may be of great value, the hammer problem may be greater than it may seem. Need this done right the very first time? If so, an emergency plumber will certainly be your best option to manage this kind of problem.

A Traditional Remedy for Repairing A Water Hammer

Older properties typically have water supply lines with pipeline installations referred to as chambers. These chambers are located on hot as well as cold water lines near each inlet valve or tap.


The chambers are rarely noticeable, other than where the area could be unfinished such as in utility rooms. Otherwise, the chambers are concealed within walls along various other plumbing lines.

Plumber-Basic Components of a Plumbing Fixture

The function of these air chambers are to serve as shock absorbers when water flows under high pressure as well as rate of speed. Essentially, the air compresses whereas water doesn’t. Because of this, the air in the chamber is compressed by the water pressure, making the water pressure halt once the tap or home appliance switches off the water circulation very quickly.


Shock waves from the highly pressurized water hit the highly pressed air in the chamber instead of hitting the water pipes. For the most part, the chambers are fabricated as well as set up on-site prior to the section where the water supply lines get to the faucets is closed off. These chambers typically have a length 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 operates as the shock absorber gets eliminated. It’s possible to recharge these chambers that have become full of water by merely shutting off the water supply of the affected pipelines and then draining all water from the pipes. By doing so, the air is enabled to flow back again into the chamber to fill it up again.


As soon as the water gets turned 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 Utilize Water Hammer/Hydraulic Shock Arrestors

The most long-term as well as reliable approach of eliminating the problem of water hammers in water lines is installing hydraulic shock arrestors on supply lines that make sounds.


These arrestors work like air chambers, however they include a closed gas or air-filled chamber. The seal is typically developed 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 guaranteeing the gas or air as well as water are always divided.

Instructions for Installment:.

Products as well as Devices Needed:

Listed here are the basic tools as well as products needed to mount a hydraulic shock absorber:


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


Step 1: Turn off the primary supply of water valve.

Shut the major water supply or merely the water valve leading to the dish-washing machine, toilet, or the washing unit by using the valve near the fixture or home appliance.


Most appliances come with 2 shutoffs for shutting down the water circulation, one for the cold water line and another for the hot water line. Toilet have typically only one valve.


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

Step 2: Disconnect the supply of water tubes.

Take a towel or container and put under or around the work area in order to capture all water that may splash. Next, separate the hose pipe or tube that supplies water to the fixture, shutoff, or home appliance valve.


The arrestors should be set up onto either the inlet of the fixture or on the valve or the home appliance outlet. It’s best to install 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 (variable one) to loosen all tight compression nut that connects the tube or tube to the valve.

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

Utilize tape to wrap the water inlet or valve male threads (depending upon the area you removed the supply tubing or tube). You can make use of thread-seal or Teflon tape known as plumber’s tape. Wrap it clockwise around the strings for three to 4 times as well as the arrestor’s male threads the same way.

Step 4: Set up the hydraulic shock arrestors.

Take the arrestor and thread it onto the inlet or valve while turning the female fixture or fitting clockwise up until it’s hand-tight. In case you’re handling compression installations on the toilet or dish-washing machine valve, affix the tubing of the arrestor into each compression fitting.


Now, slide each compression ring onto the valve and thread the arrestor tubing into the fitting while sliding the ring onto the valve. Next, thread the arrestor onto the compression fitting’s nut by using 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.

Attach each water supply hose pipe or tube to every arrestor by using the tongue/groove pliers or an adjustable monkey wrench to tighten them. You can now turn on water circulation from where you turned it off, be it from the major valve or the valve near the appliance. Switch the valve on up until it’s totally open.


You can purge your toilet or run the dish-washing machine or cleaning unit for a cycle to test whether the arrestors are working properly. If you encountered an issue and need help, speak to a professional plumber.
