Resolution to noisey water pipes for washing machine

This product was my resolution to the new washing machines use of "low water consumption". My new front loader was shaking the pipes as it did the wash. Didn't happen with the older washing machine. Installed one each on Hot & Cold water supplies and problem is gone. Simple fix.

Other brand worked. This did not. Oatley support failed

I can't seem to update my previous review, so this is an update to my first review. Avoid this Oatley Hammer Arrestor and get the Sioux Chief version. The rating of the hammer arrester is the same which is a AA, but Sioux Chief version worked while the Oatley one did not. I suggest avoiding Oatley if possible because their company is incompetent. Read more below. I have an LG washing machine that caused water hammering. I bought this Oatley hammer arrestor despite seeing bad reviews of it. Indeed, it did not work. I ran my laundry a few times just in case the device needed some break-in period. No luck. I reached out to Oatley technical support at technical@oatey.com to see if they have any suggestions because my "hammer arrestor is not working" and the "hammering continues". I'm thinking, maybe it's me, and I'll ask the experts. Their technical support told me, "If you still hear a banging noise, check to see if enough straps are holding the pipes in place. If not, add more. Using clips and plumber's tape will further restrict pipe movement." I don't need to be a plumber to know this was a ridiculous response. I have water hammering, and they told me to strap my pipes. I bought the Sioux Chief version, which worked on my first laundry wash. My hammer problem is solved. I thought Oatley was a big, reputable brand, but their product is defective, yet they continue to sell it. Their support is also just a flat-out waste of time. I recommend avoiding their brand if possible.

I would buy this item again

SupplyHouse is an excellent place to buy Home projects supplies for DIYers. You can get quality name brand products at good price. I bought these hammer arrestors for our washing machine. So far they are functioning well.

Did Not Work Well

I bought this product about 3 years ago and there was some improvement with the pipes banging. I would say it reduced the noise about 50%. After a couple of years the noise got a bit louder and I started looking for a replacement and reading reviews. I bought the Sioux Chief brand. The arrestor portion is twice as long. I am very happy with my new model arrestor. I would highly recommend the Sioux Chief brand. They both were easy to install.

Didn't work

Purchased these from a local supplier about a year ago. Worked fairly well with old washing machine. After installing new Maytag with "Water Saving" Technology, the water hammer was so bad it popped open a Sharkbite elbow over the furnace, and damaged it. Purchased two Sioux Chief arrestors (SKU 660-H) from Supply House. No water hammer since. Important to note that new clothes washers don't fill tub. Water squirts in fast, frequent burst causing severe water hammer .

Quiet Pipes

Received the water hammer arresters very soon after placing the order with SupplyHouse. Easy to install and they have solved the water hammer problem with our washing machine.

Bad product

I've seen other reviews here and on other sites that this does not work. Indeed, this did not help my situation. Banging continues. It is rated a size AA but it is really small. I can't tell if this is normal or not.
