5 Handy Steps for Correcting Water Hammer Problems in Your Plumbing

The Perfect Device to Help Solve Plumbing System Water Noises and 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 get a banging noise throughout your house. The pipes are really shifting and impacting something. This banging force can be strong enough to break pipe joints apart which could trigger real problems.

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 provides the water someplace to go because the air is compressible.


A water hammer issue can happen suddenly, especially when turning off a kitchen or bathroom faucet or any other tap very quickly. It simply creates some vibrations via the  pipes which causes the hammer noises.


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


A water hammer actually is fairly an frustrating issue, but is also one that can result in problems to the system. Nonetheless, the most ideal option to fix this issue is by mounting 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 typical noise concern in a system. It normally occurs when some appliances or faucets very quickly shut off the water circulation.


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

This concern can additionally arise from other appliances or fixtures, such as washing machines and dishwashers. These cleaning appliances normally come with solenoid shutoffs which turns off water circulation very rapidly such that it goes from on to off within a second.


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

A Conventional Solution for Repairing A Water Hammer

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


The chambers are hardly noticeable, except where the room may be unfinished such as in laundry room. Or else, the chambers are hidden within wall surfaces along various other plumbing lines.

Plumber-Basic Components of a Plumbing Fixture

The role of these air chambers are to serve as shock absorbers when water moves under high pressure and rate of speed. Essentially, 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 tap or appliance switches off the water circulation very quickly.


Shock waves from the extremely pressurized water hit the extremely compressed air in the chamber as opposed to hitting the water pipes. The chambers are fabricated and installed on-site prior to the area where the water supply lines get to the faucets is closed off. These chambers normally have a length of around 12 inches or longer, with a similar diameter size to that of the pipes.


If makeshift chambers get loaded with water with time, the air that works as the shock absorber gets removed. It’s possible to charge these chambers that have become loaded with water by just shutting off the water supply of the affected pipes and then draining all water from the pipes. By doing so, the air is permitted to flow back again right into the chamber to load it up again.


Once 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 set up water hammer/hydraulic shock arrestors near each tap.

How to Use Water Hammer/Hydraulic Shock Arrestors

One of the most effective and lasting method of removing the issue of water hammers in water lines is mounting hydraulic shock arrestors on supply lines that make noise.


These arrestors work like air chambers, however they come with a closed gas or air-filled chamber. The seal is normally produced by a piston or diaphragm.


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

Directions for Installment:.

Materials and Equipment Needed:

Listed here are the basic tools and supplies needed to set up a hydraulic shock absorber:


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


Step 1: Shut off the main supply of water valve.

turn 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 appliance.


A lot of appliances come with 2 shutoffs for turning off the water circulation, one for the cold water line and another for the warm water line. Toilet have normally only one valve.


Dish washers normally have one valve on the hot water line. Simply switch the water valve clockwise till it’s tightly closed. Make sure to completely stop the water circulation between the fixture or appliance and the valve.

Step 2: Detach the supply of water tubes.

Take a towel or pail and put under or around the work area in order to capture all water that might spill. Next, detach the hose or tube that provides water to the fixture, appliance, or shutoff valve.


The arrestors need to be installed onto either the inlet of the fixture or on the appliance or the valve outlet. It’s best to install the arrestor closest to the fixture or appliance.


Make use of tongue/groove pliers to loosen tight supply tubes. You can additionally utilize a wrench (variable one) to loosen all tight compression nut that connects the tube or pipe to the valve.

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

Utilize tape to cover the water inlet or valve male threads (depending upon the spot you detached the supply tubes or pipe). You can utilize 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 same way.

Step 4: Set up the hydraulic shock arrestors.

Take the arrestor and thread it onto the inlet or valve while revolving the female fixture or fitting clockwise till it’s hand-tight. In case you’re handling 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 moving the ring onto the valve. Next, thread the arrestor onto the compression installation’s nut by using the  tongue/groove pliers to tighten up the arrestor onto the fitting, then utilize an adjustable monkey wrench to tighten up the nut.

Step 5: Reconnect the supply hoses or tubes.

Attach 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 at this time switch on water circulation from where you turned it off, be it from the primary valve or the valve near to the appliance. Turn the valve on till it’s completely open.


You can now purge your toilet or run the dish washer or washing unit for a cycle to test whether the arrestors are working properly. Examine the connections for any leakage and tighten up all with a wrench or pliers. If you still need help, because you encountered an problem, call a professional plumber.
