5 Useful Steps for Correcting Water Hammer Problems in Your Plumbing

The Perfect Tool to Help Solve Plumbing Water Noises and also Water Hammer in House Piping

In some plumbing systems when a faucet or an automated valve like in a washing machine stops the water too quick, it attempts to keep going and you get a banging sound throughout the house. The pipes are in fact shifting and also impacting something. This banging force can be strong enough to damage pipeline joints apart which could cause real issues.

This phenomenon is known as a “Water Hammer” which can be solved by placing 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 all of a sudden, most notably when turning off a kitchen or washroom faucet or any other faucet rapidly. It basically produces some vibrations through 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 high water pressure within the pipes.


A water hammer actually is rather an annoying issue, but is also one that can cause damages to the system. Nonetheless, the most reliable resolution to repair this problem is by mounting a water hammer/hydraulic shock arrestor. This device can be easily installed in various types of supply lines.

This hydraulic shock impact of water hammers can be the most typical noise issue in a system. It generally occurs when some home appliances or faucets rapidly shut off the water circulation.


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

This issue can also arise from other home appliances or fixtures, such as dish-washing machines and also washing machines. These cleaning units generally include solenoid valves which turns off water circulation very fast such that it goes from on to off within a second.


These ideas may be of good value, the hammer problem may be more than it may appear. Need this done right the first time? An emergency plumber will be your best choice to manage this kind of problem.

A Typical Option for Taking Care Of A Water Hammer

Older properties generally have supply of water lines with pipeline installations known as chambers. These chambers lie on cold and also hot water lines near each inlet valve or faucet.


The chambers are hardly noticeable, except where the area might be unfinished such as in laundry room. Or else, the chambers are hidden within walls along various 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 and also speed. Primarily, the air compresses whereas water does not. The air in the chamber is pressed by the water pressure, making the water pressure halt once the faucet or home appliance turns off the water circulation rapidly.


Shock waves from the highly pressurized water hit the highly pressed air in the chamber instead of hitting the water pipes. The chambers are fabricated and also installed on-site before the area where the water supply lines reach the faucets is closed off. These chambers generally have a length of around 12 inches or longer, with a comparable diameter size to that of the pipes.


Nonetheless, 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 filled with water by simply switching off the supply of water of the affected pipes and then draining all water from the pipelines. By doing so, the air is permitted to flow back again into the chamber to load it up once more.


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 faucet.

Just How to Make Use Of Water Hammer/Hydraulic Shock Arrestors

One of the most efficient and also lasting approach of removing the problem of water hammers in water lines is mounting hydraulic shock arrestors on supply lines that make sounds.


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


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

Guidelines for Installation:.

Supplies and also Tools Needed:

Listed here are the basic tools and also supplies needed to mount a hydraulic shock absorber:


  • Towel or bucket
  • 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 major water supply valve.

Close the main water supply or simply the water valve leading to the dish washer, toilet, or the washing appliance by using the valve near the fixture or home appliance.


The majority of appliances featured two valves for turning off the water circulation, one for the cold water line and another for the warm water line. Toilet have generally only one valve.


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

Step 2: Disconnect the water supply tubes.

Take a towel or bucket and place under or around the work area in order to capture all water that may spill. Next, detach the pipe or tube that supplies water to the home appliance, shutoff, or fixture valve.


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


Use tongue/groove pliers to loosen tight supply tubes. You can also utilize a wrench (adjustable 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.

Apply tape to cover the water inlet or valve male threads (depending on the area you removed the supply tubes 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: 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 until it’s hand-tight. In case you’re handling compression installations on the toilet or dish washer valve, affix the tubes of the arrestor into each compression installation.


Now, slide each compression ring onto the valve and thread the arrestor tubes into the fitting while moving the ring onto the valve. Next, thread the arrestor onto the compression installation’s nut by utilizing 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.

Connect each supply of water 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 circulation from where you turned it off, be it from the main 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 washer or washing appliance for a cycle to check whether the arrestors are functioning properly. Inspect the links for any leakage and tighten up all with a wrench or pliers. If you still need aid, because you encountered an problem, contact a professional plumber.
