These items are difficult to find locally so it is great that Amazon carries them. I would caution using this item with a solder tee fitting. After soldering all items together and wrapping the arrestor in three layers of wet towels in order to mitigate heat damage, the job was finished. I tested faucets around the house, pipe banging was still obvious, gave it a few days to make sure things didn't need to "settle in." After a week, things had not been fixed at all. I took the assembly apart, figuring something went wrong. When inspecting the arrestor, it seems being able to keep the arrestor cool enough not to melt the insides and keeping the tee hot enough to pull in the solder is near impossible. The entire interior plastic piece had melted and was certainly not creating the seal necessary to buffer water hammer. I reassembled another arrestor with "shark bite" connectors and it seems to be working a bit better, but certainly does not mitigate all the water hammer. I suspect you would need a pair of these in every supply line tied directly to the faucet/fixture in question. Merely installing these on a branch line which services many problem fixtures does little to nothing. I am not sure I would recommend this to others.

This gadget was a necessity when certain types of devices had quickly opening and closing valves and could create a destructive hydro-shock in water pipes known as water hammer. These days, even washing machines have redesigned valves which do not close instantly. The plumbing code may vary in different locales, but it seems that in most places residential homes are exempt from the requirement to have water hammer arresters installed. Consequently, it is an optional plumbing accessory which big box retailers no longer carry since there is not much demand - but Amazon conveniently offers them... Can be soldered to any 1/2 copper pipe inside of the wall. Small enough to fit anywhere. Offers a balance of slight benefit of absorbing an unlikely (in modern residential house) water hammer with a slight risk of leakage in additional soldered joint... 5 starts because it is a solid product made by a reputable company.

I use this on the hot water supply line to my dishwasher. The solenoid on the dishwasher closes very abruptly and caused a pretty loud water hammer. With this device installed, no more noise. I also installed a similar Sioux Chief arrestor on the washing machine and it, too, has eliminated any water hammer noise. I would think these devices would help prevent damage to the water pipes and the appliances.

Really stops the banging associated with appliances (washing machines, diswashers, etc.) that shut the water off suddenly.

Thoughts about installation:
- Put it as close to the offending shutoff valve as reasonably achievable. Don't worry about direction.
- Rather than sweating it directly into the plumbing, consider putting a pipe thread adapter onto this (along with the mating one in the plumbing) so it can be conveniently replaced if needed.

The price was very good, it did the job, was easy to install and Amazon made it extremely easy to order.
I could not install it right away but it was here in two days.
Amazon saves me both time and money.

Installed an Orbit timer Orbit 62040 2-Dial Digital Hose Faucet Watering Timer which has a quick acting valve and the 40 year old 20 foot 3/4" copper supply line nearly slapped the bottom of the house first time it closed. It obviously bothered the customer, and could lead to damage on older joints, so I cut in and added a reducing tee, then the arrester. Took about 10 minutes. I should have but did not wrap the device with a heat sink, just soldered it in with minimum heat. The results were immediate and exactly what was expected; no banging at all. If you have trouble with precise heat control in your pipefitting, get one of these Sioux Chief Mfg 660-2 1/2-Inch MIP Thread Mini Rester Residential Water Hammer Arrester use threaded fittings where you can and simply screw the thing in.

Great product. I have an old house with copper pipes that were not planned out well. I've been going back and reworking as much as I have time for...(NOTE: Author is NOT a plumber). Some of the old valves in my house have terrible fluid hammer...always beating and banging my OLD pipes. I have installed 3 of these units in different configurations and I have nearly eliminated all of my fluid hammer. The one on the washing machine made it so you can't hear the water turn off when you are standing right in front of it. Great product.

I started getting "water hammer" on an ice maker line for a refrigerator. I installed this in the crawlspace as close as I could to the line feeding the fridge and the problem was solved.
