In our copper piping systems, water hammer creates noticeable audible sounds but PEX pipe dampens the sound, but it does not eliminate water hammer. As newer technologies like solenoid valves regulate the amount of water we use, it forces the plumbing system to go on/off more than before, causing more pressure spikes.

Is a hammer arrestor necessary?
The general rule is that water hammer arrestors are required on all quick closing valves.
How do I stop my water pipes from hammering?
One method for eliminating water hammers is to create new air chambers that will serve as cushions for shockwaves. To do this, shut off your home’s main water valve, then open the highest faucet in your home. Next, turn on the lowest faucet in your home and keep it on until all water has drained.
Why are my water pipes hammering?
Water hammer is a loud bang coming from the pipes after a fill valve shuts off. This type of plumbing noise is typically due to worn or damaged faucet washers. A buildup of minerals and rust inside the shut-off valves may also cause this sound.
How do you know if you need a water hammer arrestor?
Do I need water hammer arrestor on hot and cold?
Properly sized water hammer arresters should be installed on the hot and cold water supply piping to that fixture, equipment or apparatus wherein shock can be produced. A pressure reducing valve installed on the discharge side of the water meter can be most helpful in protecting the residential piping system.
Do water hammer arrestors wear out?
Stainless steel constructed (chamber-style) water hammers seldom, if ever, need replacing and are guaranteed for the life of the plumbing. Unlike piston-type units, which have moving parts, chamber-style arrestors have a proven track record, according to Jay R.
Can you make your own hammer arrestor?
A water hammer arrestor acts like a shock absorber by adding an air pocket in the water line. Making a homemade water hammer arrestor is inexpensive and simple. This project requires basic plumbing skills and tools.
Where do I need hammer arrestors?
Why do I suddenly have water hammer?
Water hammer is usually caused in high pressure (e.g. mains pressure) water systems either when a tap is turned off quickly, or by fast-acting solenoid valves, which suddenly stop the water moving through the pipes and sets up a shock wave through the water, causing the pipes to vibrate and ‘shudder’.
Can water hammer fix itself?
You can cure water hammer by turning off the water behind the waterlogged chamber, opening the offending faucet and permitting the faucet to drain thoroughly. Once all the water drains from the chamber, air will fill it again and restore the cushion.
Should I call a plumber for water hammer?
Toilets should automatically refill. Once all the faucets are closed and the toilets are filled, you can check for water hammer by flushing the toilets. If this method doesn’t work, try reducing the flow from the shut-off valves. You might also want to call a professional plumber to help you out.

Can a water hammer arrestor be installed anywhere?
“Water hammer arresters shall be specifically sized and have sufficient volume of air to dissipate the calculated kinetic energy generated by closing residential or commercial faucets or valves. Arresters shall be installed on both hot and cold lines on the supply stops where applicable.
