5 Practical Steps for Correcting Water Hammer Problems in Your Plumbing

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

In some plumbing systems when a tap or an automated valve like in a washing machine stops the water too quickly, it tries to keep going and you obtain a banging sound throughout your home. The pipelines are really shifting and also impacting something. This banging force can be strong enough to damage pipe joints apart which could cause real issues.

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


A water hammer problem can occur suddenly, even more so when shutting down a kitchen or restroom faucet or any other tap fast. It simply generates some vibrations via 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 high 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. Nonetheless, the ideal option to fix this problem is by installing a water hammer/hydraulic shock arrestor. This device can be easily mounted in different types of supply lines.

This hydraulic shock effect of water hammers can be the most usual noise problem in a system. When some appliances or faucets fast close off the water flow, it typically happens.


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

This problem can additionally result from other appliances or fixtures, such as washing machines and also dish-washing machines. These cleaning machines typically feature solenoid shutoffs which shuts off water flow extremely rapidly such that it goes from on to off within a second.


Although these pointers may be of great value, the hammer problem may be greater than it may appear. Need this done right the first time? If so, an emergency plumber will certainly be your ideal choice to handle this kind of problem.

A Traditional Resolution for Dealing With A Water Hammer

Older dwellings typically have water lines with pipe fittings called chambers. These chambers lie on cold and also hot water lines near each inlet valve or tap.


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

Plumber-Basic Components of a Plumbing Fixture

When water moves under high pressure and also rate of speed, the role of these air chambers are to act as shock absorbers. Essentially, the air compresses whereas water doesn’t. Thus, the air in the chamber is compressed by the water pressure, making the water pressure halt once the tap or home appliance turns 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 and also set up on-site before the area 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 similar diameter size to that of the pipelines.


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


When 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.

Just How to Use Water Hammer/Hydraulic Shock Arrestors

One of the most long-term and also effective technique 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, yet they feature a closed gas or air-filled chamber. The seal is typically created 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 ensuring the gas or air and also water are always separated.

Guidelines for Installation:.

Products and also Tools Needed:

Listed here are the basic devices and also supplies needed to install a hydraulic shock absorber:


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


Step 1: Shut down the primary water valve.

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


The majority of appliances featured two shutoffs for shutting down the water flow, one for the cold water line and another for the warm water line. Toilet have typically only one valve.


Dish-washing machines typically have one valve on the hot water line. Simply switch the water valve clockwise until it’s firmly closed. Make sure to totally stop the water flow between the fixture or home appliance and the valve.

Step 2: Detach the water tubes.

Take a towel or container and place under or around the work area in order to catch all water that may spill. Next, detach the hose pipe or tube that provides water to the home appliance, fixture, or shutoff 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 ideal to mount the arrestor closest to the fixture or home appliance.


Use tongue/groove pliers to loosen up tight supply tubes. You can additionally utilize a wrench (variable one) to loosen up 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.

Apply tape to cover the water inlet or valve male threads (depending upon the area you detached the supply tubing or pipe). You can utilize thread-seal or Teflon tape known as plumber’s tape. Wrap it clockwise around the strings for three to four times as well as the arrestor’s male threads the same way.

Step 4: Install the hydraulic shock arrestors.

Take the arrestor and thread it onto the inlet or valve while turning the female fixture or fitting clockwise until it’s hand-tight. In case you’re dealing with compression fittings 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 moving the ring onto the valve. Next, thread the arrestor onto the compression fitting’s nut by utilizing the  tongue/groove pliers to tighten the arrestor onto the fitting, then utilize an adjustable monkey wrench to tighten the nut.

Step 5: Reconnect the supply hoses or tubes.

Connect 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 switched it off, be it from the major valve or the valve near the appliance. Switch the valve on until it’s totally open.


You can now flush your toilet or run the dish-washing machine or washing machine for a cycle to test whether the arrestors are working properly. Examine the links 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.
