PEX Water hammer

[Dimitrivich]

I recently moved into new construction with PEX. I have auto shut off timers on my hose bibs to help in watering the new lawn and they're causing some water hammer when they shut off. A crimp on water hammer arrestor is about $20 from the big box store. I am new to running PEX. Can I simply make my own arrestor like I would with copper? Put a T at the end of the line (going vertical) with 6" of PEX and a plug at the top? I don't see why it wouldn't work, but I am new to PEX work. I could spend $0 with this method or burn $80 on official arrestors. I just want to make sure I'm not asking for PEX to perform a task that isn't within it's specs.

Sorry if that has been discussed previously, but I can not find a decent way to search the forums.

you problem with pex is you have a section some where that is not strapped down.

bet you a stale day old donut when the valve turns off a pipe is slapping against a 2x4 find the source of the noise

That stale donut is way more than a day old Frodo, you have been putting that on the table for months!

I would guess he's had no takers and it would be a shame to toss it.
