This can be fixed by draining your plumbing system, which requires turning off the main water valve and opening the highest faucet in your home. Then drain water from the lowest faucet. The chamber should fill up with air once the water is drained and resolve your water hammer problem.
Drain your pipes and refill them to create new air chambers
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. Finally, reopen the main water valve to refill your pipes.
The chambers can fail, though, because water under pressure gradually absorbs the air. If you never had hammering and then it suddenly starts, most likely your plumbing system's air chambers have become waterlogged.
Air chambers often end up filled with water from the pressure changes and no longer work to absorb the shock. The only solution is to drain the entire system to "recharge" the air chamber. A more practical and enduring solution is using water hammer arrestors.
A common cause of water hammer is high water pressure. If your pressure is running near 100 psi, then it's likely the cause of your issue. Normal pressure should be approximately 30 to 55 psi. To solve this problem, consider installing a water pressure regulator.
Yes. A water hammer can cause a pipe rupture which results from a break in the pipe system. This effect occurs if the pipe is not equipped to handle the pressure and instead ruptures or bursts. This can also happen when the pipe joints weaken from the pressure of the hydraulic shock.
A faulty toilet fill valve that doesn't close completely or a quick-closing fill valve are both possible causes of water hammer that occurs after you flush a toilet.

Installing Pressure Regulating Devices
High water pressure is a frequent reason for water hammering. Your problem is probably caused by your pressure, which is close to 100 psi. 30 to 55 psi is considered normal pressure. Consider hiring a plumber to install a water pressure regulating device to address this issue.
Plumbers can fix this problem in several ways, the most common of which is installing a water hammer arrestor. Loose pipes: If a pipe is dangling from its fixture when it should be securely attached to the ceiling or wall, it's likely to move around when water flows through it.
Left untreated, water hammer can lead to actual damage to pipework, appliances and components of any system. Over time this damage can accumulate and result in the premature failure of parts of the plumbing system and all the watery hassle that can cause.
Ignoring water hammer can ultimately result in the catastrophic failure of your flow system. The long-term effects of water hammer can include: Pump and Flow System Damage.
Enough force from water hammer can even cause pipes to burst. If you hear rattling sounds along with the water hammer, it likely means you have pipes coming loose.
Without mitigation from the proper kind of valve or pipe closure, water hammer can cause equipment damage and pose safety concerns in industrial settings. It can also cause leaks in the home and damage to residential appliances and property, especially if it goes untreated for a significant amount of time.
If you're hearing banging noises at random, even while no water is running, it's likely that there's some sediment buildup at the bottom of your water heater. If this is the case, what you're hearing is the resulting reverberations of steam bubbles coming out of that built-up sediment.
The best places are either close to the pump, isolation or check valve that is originating the hammer, or at more distant points where the pipe changes direction, for example at the top of a pump riser.
Water arrestors by their design are an addition to the pipe. A little air chamber that extends perpendicular off each that is sealed off from water. When the water moves suddenly in the pipe that air chamber absorbs the shock. As they get used though, over time they wear out making them ineffective.
If you hear a vibrating, banging or pounding noise when taps are turned on or off it's usually due to hydraulic shock in your plumbing pipework. Hydraulic shock is more commonly known as “water hammer”. The banging noise you hear is the result of vibrations in pipes.
Once all your faucets are turned on, including the outside spigots, turn the water valve all the way on. Let the water run through all of your faucets for 10-15 minutes to make sure you are seeing a steady stream of water, or aren't hearing any noises coming from your piping anymore.
If you hear a banging or a bumping noise coming from your pipes after you flush the toilet, you likely have a water hammer issue on your hands. This shockwave effect occurs after a sudden change in water pressure, causing the pressurized water to bang against the valve opening.
Hammering can be caused by waterlogged air chambers, clogged chambers, or excess pressure in your plumbing system. It can also be the result of a valve or pipe clog, which can produce a staccato banging sound.
Loud noises coming from plumbing pipes could be a sign of a serious problem. These are the top three causes of banging plumbing pipe sounds: Water hammer, expanding/contracting copper pipes, and water pressure that is too high.
Stop valves, commonly referred to as stopcocks, can cause water hammer if their gland packing is lose and/or they have worn washers.
For this one, you can hire a reliable plumber to attach a water hammer arrestor to your vibrating pipes. Unfortunately, this is a highly invasive process that requires a plumber to cut into your walls. So instead, a more straightforward fix may be to replace your toilet fill valves with slower closing fill valves.
