If you want to add a second arrestor, put it in series (end to end) with the exisitng arrestor. Also add copper tube straps if your piping is extremely loose. HD carries the tube straps.

If you have a shut off and a flex line going to the sink. All you need to do is shut it off and unscrew compression nut at end of flex line. This comes with a compression fitting that unscrews (dis guard it) and then you have a male and a female on Arrestor. install unit in between shut off and flex line.

Can the arrestor work in a horizontal position?

I believe it says it can be mounted in any direction.

The Water Hammer Arrestor is what I've been looking for but didn't know it until I happened to search for it. I had always thought that water hammer arrestors had to be soldered into the mains, but I'd already closed up my walls and THEN I discovered the hammer problem. Further, I have PEX pipes, apparently they're not fastened down on horizontal runs enough, because they rattle when travelling across the cold-air return and HVAC supply trunks. I found this product online, ran to Home Depot to buy it, and after I came home got it installed in about 90 seconds. 1. turn off water 2. disconnect the cold water line on my sink (in my case the hammer was on the cold, but this product should work fine for hot too) 3. use an adjustable wrench to connect to the valve 4. use an adjustable wrench to connect the faucet line to the WHA. My water hammer is completely gone. BTW, the packaging diagram looks like it's got an actual bladder/plunger in it, not just an air chamber exposed to the water flow. Note: this unit has "male" on one end, and "female" on the other end. The photo shows a nut on the left side, which is discarded unless you need to run bare plastic/copper tubing to the faucet.

just didn't work .... waste of time and money (although HD did accept the return). Installed an "empty" vertical capped pipe and it worked like a charm.

Bought two of these, for hot and cold connections to new kitchen sink faucet. Faucet was causing water hammer in pipes when shutting off flow. These did nothing to stop the water hammer, which still happens about the same as before installing them. They were easy to install, and appear well made, but they don't work.

works but needed 2
Got a very subtle hammer when turning on the hot water tap during cold season possibly due to pipe loosen around its fastener. Got 1 to put on the hot side and seems to helps abit so I got another to put on the cold side. Both seems to help but I would say 99.9% cause sometimes the hammer can be heard, but much much softer. Also don't expect it to work immediately. it took a few days before we notice it working, maybe due to the stiffen spring or rubber plunger, not sure.

Bought 3 to install in all our toilet tank connectors but this doesn't make even the smallest difference to water hammer/knocking pipes. Not worth it, cant return the 2 opened once but I will be returning the 3rd one. Some people have luck with it so I guess it works on very minor pressure or maybe other locations but not same for everyone, I advice to buy and try one before bulk ordering If anyone is thinking to do that.
