5 Practical Steps for Correcting Water Hammer Problems in Your Plumbing

The Perfect Device to Help Solve Plumbing Water Noises as well as Water Hammer in House Pipeline

In some plumbing systems when a tap or an automated shutoff like in a washing machine stops the water too fast, it tries to keep going and you obtain a banging noise throughout your home. The pipes are in fact shifting as well as banging into something. This banging force can be strong enough to damage pipe joints apart which could cause real problems.

This phenomenon is known as a “Water Hammer” which can be addressed by placing a unique 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 occur all of a sudden, especially when shutting down a kitchen or washroom faucet or any other tap fast. It simply generates some vibrations via the  pipes which causes the hammer noises.


These noises are comparable to shock waves that will make fixtures, pipes and taps to shake. Technically, this event is a type of hydraulic shock, caused by high water force within the pipes.


A water hammer actually is quite an aggravating issue, but is also one that can result in problems to the system. However, the most effective remedy to fix this problem is by mounting 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 issue in a system. It usually happens when some appliances or taps fast shut down the water flow.


The speed at which water flow is stopped is what leads to those shock-waves which makes the supply lines bang against each other and framing members such as flooring joints as well as wall studs or on each other.

This issue can likewise result from other appliances or fixtures, such as dishwashers as well as washing machines. These washing appliances usually feature solenoid valves which shuts off water flow really quickly such that it goes from on off within a second.


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

A Traditional Solution for Taking Care Of A Water Hammer

Older dwellings usually have water supply lines with pipe installations referred to as chambers. These chambers lie on cold as well as hot water lines near each inlet shutoff or tap.


The chambers are barely noticeable, other than where the space may be unfinished such as in utility rooms. Otherwise, the chambers are hidden within wall surfaces along various other plumbing lines.

Plumber-Basic Components of a Plumbing Fixture

When water moves under high force as well as speed, the duty of these air chambers are to act as shock absorbers. Essentially, the air compresses whereas water does not. Therefore, the air in the chamber is compressed by the water force, making the water force halt once the tap or appliance switches off the water flow fast.


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 as well as mounted on-site before the section where the water supply lines reach the taps is closed off. These chambers usually have a size of around 12 inches or longer, with a comparable diameter size to that of the pipes.


However, if makeshift chambers get full of water with time, the air that works as the shock absorber gets eliminated. It’s possible to charge these chambers that have become filled with water by simply switching off the water supply of the affected pipes and then draining all water from the pipes. By doing so, the air is allowed to flow back again right into the chamber to load it up once more.


When the water gets switched 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.

Exactly How to Utilize Water Hammer/Hydraulic Shock Arrestors

The most effective as well as long-lasting method 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, however they feature a closed gas or air-filled chamber. The seal is usually created by a piston or diaphragm.


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

Instructions for Setup:.

Materials as well as Equipment Needed:

Listed here are the basic devices as well as materials needed to set up 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 off the main water system valve.

First, shut down the main water supply valve or simply the water flow to the dish washer, toilet, or washing appliance using the valve near the unit.


The majority of appliances featured two valves for shutting down the water flow, one for the cold water line and another for the warm water line. Toilet have usually only one shutoff.


Dish washers usually have one shutoff on the hot water line. Simply switch the water shutoff clockwise up until it’s tightly closed. Make sure to completely stop the water flow between the fixture or appliance and the shutoff.

Step 2: Separate the water system 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 supplies water to the shutoff, fixture, or appliance shutoff.


The arrestors should be mounted 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.


Utilize tongue/groove pliers to loosen up tight supply tubes. You can likewise use a wrench (variable one) to loosen up all tight compression nut that connects the tube or hose pipe to the shutoff.

Step 3: Cover 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 spot you detached the supply tubing or hose pipe). You can use 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 revolving the female fixture or fitting clockwise up until it’s hand-tight. In case you’re dealing with compression installations on the toilet or dish washer valve, affix the tubing of the arrestor right into each compression installation.


Now, slide each compression ring onto the valve and thread the arrestor tubing 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 use an adjustable pipe wrench to tighten up the nut.

Step 5: Reconnect the supply hoses or tubes.

Connect each water supply hose pipe or tube to each arrestor by using the tongue/groove pliers or an adjustable pipe wrench to tighten them. You can now switch on water flow from where you switched it off, be it from the main shutoff or the valve near the appliance. Turn the shutoff on up until it’s completely open.


You can now purge your toilet or run the dish washer or washing appliance 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. Call a professional plumber if you encountered an problem and need assistance.
