5 Handy Steps for Fixing Water Hammer Problems in Your Plumbing

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

In some plumbing systems when a faucet or an automatic valve like in a washing machine stops the water too fast, it tries to keep going and you get a banging sound throughout your house. The pipelines are in fact moving as well as hitting something. This banging force can be strong enough to break pipe joints apart which could create real issues.

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


A water hammer problem can take place unexpectedly, mainly when shutting off a kitchen or shower room tap or any other faucet fast. It simply creates some vibrations via the  pipelines which causes the hammer noises.


These noises 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 higher than normal water pressure within the pipelines.


A water hammer actually is quite an aggravating issue, but is also one that can lead to damages to the system. The ideal solution to repair this issue is by setting up a water hammer/hydraulic shock arrestor. This device can be easily installed in different types of supply lines.

This hydraulic shock effect of water hammers can be the most usual sound problem in a system. When some home appliances or taps fast close off the water flow, it usually takes place.


The rate of speed at which water flow is stopped is what causes 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 problem can also result from other home appliances or fixtures, such as dishwashers as well as washing machines. These washing machines usually include solenoid valves which shuts down water flow 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 seem. Need this done right the first time? If so, an emergency plumber will be your ideal option to handle this kind of issue.

A Conventional Remedy for Dealing With A Water Hammer

Older dwellings usually have water lines with pipe installations known as chambers. These chambers are located on cold as well as hot water lines near each inlet valve or faucet.


The chambers are hardly visible, other than where the space could 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 pressure as well as rate of speed, the role of these air chambers are to act as shock absorbers. Generally, the air compresses whereas water does not. Because of this, the air in the chamber is compressed by the water pressure, making the water pressure halt once the faucet or appliance switches off the water flow fast.


Shock waves from the highly pressurized water hit the highly compressed air in the chamber instead of hitting the water pipes. The chambers are fabricated as well as set up on-site before the area where the water supply lines reach the taps is closed off. These chambers usually have a length of around 12 inches or longer, with a similar diameter size to that of the pipelines.


Nonetheless, if makeshift chambers get loaded with water with time, the air that works as the shock absorber gets eliminated. It’s possible to recharge these chambers that have become loaded with water by merely switching off the water of the affected pipelines and then draining any water from the pipes. By doing so, the air is enabled to flow back again into the chamber to load it up once more.


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 install water hammer/hydraulic shock arrestors near each faucet.

How to Use Water Hammer/Hydraulic Shock Arrestors

The most long-term as well as reliable approach of removing the issue of water hammers in water lines is setting up hydraulic shock arrestors on supply lines that make sounds.


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


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

Directions for Setup:.

Products as well as Equipment Needed:

Listed here are the basic devices as well as products needed to install 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 major supply of water valve.

turn the primary water supply or merely the water valve leading to the dish-washing machine, toilet, or the washing appliance by using the valve near the fixture or appliance.


The majority of appliances included 2 valves for shutting off the water flow, one for the cold water line and another for the warm water line. Toilet have usually only one valve.


Dish washers usually 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 flow between the fixture or appliance and the valve.

Step 2: Detach the supply of water tubes.

Take a towel or container and place under or around the work area in order to capture any water that might spill. Next, disconnect the hose pipe or tube that supplies water to the fixture, shutoff, or appliance valve.


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


Make use of tongue/groove pliers to loosen up tight supply tubes. You can also make use of a wrench (adjustable one) to loosen up any tight compression nut that attaches 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 tubing or pipe). 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 same way.

Step 4: Mount the hydraulic shock arrestors.

Take the arrestor and thread it onto the inlet or valve while turning the female fixture or fitting clockwise till it’s hand-tight. In case you’re dealing with 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 gliding the ring onto the valve. Next, thread the arrestor onto the compression fitting’s nut by using the  tongue/groove pliers to tighten up the arrestor onto the fitting, then make use of an adjustable monkey wrench to tighten up the nut.

Step 5: Reconnect the supply hoses or tubes.

Link each water hose pipe or tube to each arrestor by using the tongue/groove pliers or an adjustable monkey wrench to tighten them. You can now switch on water flow where you turned it off, be it from the primary valve or the valve close to the appliance. Turn the valve on till it’s completely open.


You can flush your toilet or run the dish-washing machine or washing appliance for a cycle to test whether the arrestors are working properly. If you encountered an issue and need assistance, get in touch with a professional plumber.
