Is your washer the culprit? Or, a dishwasher? It can be your toilet as well!

No matter who’s making the noise, it’s high time to get rid of it. And, you know which weapon has the power to minimize the hammer? It’s the arrestor.

As the name suggests, it uses its air chamber to absorb the shocks and sounds caused by the water pressure surges due to the abrupt turning off of the valve.

Not only that, the device helps to protect the pipes in the walls and prevent the hoses from leaking as well.

So, do you want to make your house peaceful? Then check out our top list.
All the devices mentioned here promise to deliver you the utmost performance and give tough competition to each other for being the best water hammer arrestor.

How Does A Water Hammer Arrestor Work?

When you close the valve abruptly, water being non-compressible, bounces right back in the opposite direction. The change in velocity results in a pressure spike and creates an audible noise. Water hammer arrestors have been designed to reduce this noise and shocks.

It has an air chamber behind the two-sealing O-rings on the PP piston. The chamber soaks up the water momentum. Meanwhile, the piston moves due to the spike.

As it moves, gas compresses forming more space so that water enters the arrestor instead of hitting the pipes. This is how it dampens the noise and shocks as well as protects the piping system.

Comparison Chart for Water Hammer Arrestor

What To Look Before Buying Water Hammer Arrestor?

Materials

Water hammer arrestors can be made of different materials. The common ones include Brass, Copper, and Stainless Steel.

i. Brass

If you want a device for dishwashers and washing machines, then brass would be great material. It tends to resist extremely high temperatures so it can handle hot water as well. The material is a mix of copper and zinc mainly.

Being a soft metal, it can resist corrosion very well. When it comes to Brass, SharkBite 22632LF can be the best water hammer arrestor for your piping system.

ii. Copper

This material can be great for both washers and ice makers as it remains ductile in both cold and hot temperatures. Since this is true metal, it comes with a high level of strength as well as corrosion resistance.

Plus, the material doesn’t get easily damaged even if it encounters higher water pressure. If you want a coper-made device, you can consider this model by Supply Giant.

iii. Stainless Steel

Another material is great at withstanding higher temperatures more than the lowers. Stainless steel is considered a solid and rust-resistant metal. It’s an iron alloy blended with nickel and chromium.

One noticeable nature of stainless steel is that it performs incredibly better under high pressure and temperature situations than brass. Want a device in stainless steel? Then try MINI-RSTR HD660-GTR1 by Sioux Chief.

iv. Durability And Endurance

Make sure your water hammer arrestor is solid enough to function under any circumstances. The longer the durability, the later the time for the replacement.

Typically, such a device should last from 2 to 5 years. The ones with a longer lifespan can be slightly pricier but they would be worth the money.

For example, MINI-RSTR HD660-GTR1 by Sioux Chief can serve you for up to 4 years.
Also, it would be great if your arrestor can resist extreme conditions. It should have a maximum working temperature range of 180°F to 250°F, and a pressure range of 200 to 350 PSI.

Models like Sioux Chief 653-B can be great in that case.

Different Types And Sizes Of Water Hammer Arrestors

1. Single Chamber

Single chamber arrestors are mainly made of copper. Its air chamber absorbs the impact of water pressure surges while the device stays free of moisture. Such arrestors can sustain a water temp of up to 180°F.

In case you don’t have a threaded joint, there will be an option to let you solder it into the place on a T-joint. This way, you can easily fit the device into the existing water pipe. One good thing is that single chamber models wouldn’t take much space behind the interior wall.

Size

Available in ½, 1, and ¾ inch fittings, you can install it into any part of the pipe and make it shock-absorbent.

2. Mini End Stop

This arrestor has a 90° fitting and a threaded end. You can directly attach the device to the appliance’s hose connection. Whatever the case- dishwashers, washing machines, or ice makers it would fit. It’s designed to be either soldered into the pipe itself or screwed to the threaded fitting.

Although the device works best when affixed at 90° to the main piping system, its watertight chamber eliminates the pressure no matter the angles. Similar to the previous one, it would also require minimal space behind the wall panel.

Size

This water hammer arrestor is found in different sizes including 3/8-inch, 1/2-inch, 5/8-inch, 3/4-inch, and 1-inch.

3. Hose Bib Style

HB-style is pricier than the other water hammer arrestor types. It comes with a 6-inch-wide PVC (polyvinyl chloride) housing and an internal diaphragm. This design makes the arrestor disperse shock waves of water that flow through a fast-closing valve.

It can be installed straight to the water intake on an appliance like a washer. The device is better at sustaining high water pressures and temperatures than the previous two. Because it has big diameter, you may not find it ideal for installing inside the wall.

Size

The arrestor can mostly have a ¾-inch fitting.

How To Install Water Hammer Arrestor?

Water hammer arrestors can have different designs meant for different fittings and purposes. Hence, the installation method would vary from one model to another.

Let’s explain one of the ways.

A. How To Install A Sink Water Hammer Arrestor?

Step 1

Get the right kind of arrestor that matches the piping system from where you get to hear the water hammer.

Step 2

Shut off all the water outlets, especially the one that requires the device to be attached. Open the nearby faucet to drain the water and make the pipe completely empty.

Step 3

Now check whether your arrestor needs to be installed by T-fittings. If it does, attach the Tee to the pipe. Then install the arrestor on it. That said, you need to measure the Tee-fitting at first and then cut the pipe accordingly.

Make sure the cut is smaller so that the pipe can be inserted into the Tee from both ends. As you cut through the pipe, it is better to have a bucket nearby. This will be handy for catching the water that may drip down.

However, models come with different installation processes that don’t require any add-ons. So, you must check the type of your arrestor.

Step 4

Prepare the Tees, arrestor, tube endings, and copper pipes by sanding and polishing them. Then, coat them with flux.

Step 5

After attaching the T-fitting and installing the arrestor to the pipe, make sure there’s no room for water leakage.

Before you test the arrestor by turning on the water, give the joints some time to cool off or dry.

B. How To Install A Washing Machine Water Hammer Arrestor?

Step 1

Shut off the main water supply to the washing machine. Open any of the nearby faucets and relieve the pressure by draining the remaining water. Disconnect the hose from the valve.

Step 2

Thread the arrestors, one onto hot and one onto cold valves. Make sure it’s tight enough. You can snug it up with tongue and groove pliers. Just don’t overtighten it.

Step 3

Reconnect the washing machine hoses onto the arrestors and tighten them. Make sure you attach the hot water arrestor to the hot water hose.

Step 4

Turn on the water and check if there’s any leak. In case the joints are leaking, you may need to tighten them a little more with the pliers.

If the leaking stops, the washing machine is ready to use devoid of any water hammering noise.
