What Causes The Water Hammer?
Water flows with a whole lot of force when running into the supply pipe. For this reason, you hear a sound when you suddenly shut the water tap.
This is the sound of water hitting the tap and pipe. You can easily understand the reason behind this with an example.
What happens if you drive a car in 100 Miles per hour and suddenly push the brake hard? Your body is going to stress to the front suddenly, right? The same thing happens when you shut the water valve suddenly. The flow is stopped but the force is there and it is absorbed in the pipe. The banging noise comes due to the shock wave generated due to the force.
Here is a detailed visual representation of what is water hammer and why does it happen.
What is The Solution for The Water Hammer?
The solution for the water hammer is to install a water hammer arrestor. The arrestor is not a complicated tool but works well to absorb the water hammer and eliminating the sound.
Generally, it is a hollow pipe with a chamber that is used for absorbing the excess water pressure from the water supply line when the tap is suddenly shut.

Step by Step Guide To Fix The Water Hammer
Step 1
Gather all the tools and equipment that we have enlisted above. Starting work without buying any one of these can lead you to no-water for a day in your house or leakage afterward. Since other tools can do what the enlisted tools can do, you can use replacements for these tools except the water hammer arrestor, of course!
Step 2
Find an access panel in your home by which you can access the pipes. Open the access panel cover with a screwdriver, if it is screwed to the wall. Some pipe lines are insulated. You may need to remove some of the pipe insulation to unveil the plastic pipe.
Step 3
If you hear a bang when abruptly shut the tap, it is most likely that the pipe is not securely fixed to the surface properly. If all your pipes are made of metal, you can just secure the pipe with a firm surface and see whether the sound appears or not.
If the sound remains, you have to use the water hammer arrestor aka shock absorber to completely quiet the pipes. Don’t confuse yourself!
In some plastic pipeline or loose pipe, water hammer may feel enhanced due to the room for vibration. So, consider attaching the pipeline firmly without causing any pipe damage.
Step 4
Now, the main task! Turn off all the water outlets and drain down the water tank. This is necessary because you are going to cut the pipe in the next step.
If you have shut off valves installed, you may get away with shutting off water supply through the line on which you are installing water arrestors.
Step 5
Generally, water hammer arrestors are installed by T-fittings. So, you need to install the T-fittings into the pipe and then attach the shock absorber with it.
So, measure the T-fittings and cut the pipe in such a way where you will have enough room to insert the pipe into the T-fittings from both ends.
So, the cut needs to be smaller than the size of the t-fittings.
(Please remember that some shock absorbers do not need T-fittings. So, check the one you bought before installing a T-fittings.)

Step 6
Take the pipe cutter and cut the pipe according to the measurement you took. Take proper precautions so that you do not cut your finger when cutting the pipe.
Keeping some additional pipe is a good practice, in case.
Step 7
Now, install the T-fittings and solder the fittings with the pipe. You have to ensure that there is no room left for water leaking.
Step 8
After installing the T-fittings, now install our recommended water hammer arrestor to eliminate the hammer effect for good.

Why My Water Hammer Arrestor is Not Working?
One of the most common reasons behind hammer effect eliminator is not working because of the pressure reducing valve in your plumbing system. If you have a backflow prevention system installed, you may face this issue.
To combat this problem, you need to install a pressure gauge to the pipeline to monitor the pressure when your hammer arrestor is not working.
Another common reason for the shock absorbers not working is a loose pipe. So, make sure to secure your plumbing lines firmly to get the best result.
How Long Do Water Hammer Arrestors Last?
Water hammer eliminators last a lifetime if you choose to install the correct one. Quality products are supposed to withstand around half a million cycles before they become useless. So, the arrestor should not wear out before the plumbing system.
However, you may experience lesser lifespan if you install low capacity hammer absorbers in high pressure water supply pipe

I was looking for a solution of water hammer but didn’t know the name of the product. After spending ten-ish searches, I found this article. I feel this is a great piece for folks like me. Thank you
The Sioux Chief mini-resters are piston type (i.e. moving parts that wear out). They only last about 4-5 years (the warranty is 3 years). I use these to address water hammer on my LG washer and they work great for a couple years then begin to fail. I’m on my 3rd set. BTW: The pressure regulator for my home is set to 60 PSI and the expansion tank was also pre-charged to exactly this same pressure to maximize performance. I’d rather go with the Sharkbite Brass arrester now.
