DIY water hammer screw on idea.
 
I have a solenoid to control the main water supply in my house.

I can turn the solenoid on with a wireless remote, a timer, a motion detector etc.

I invented a water sensing switch that if wet will send a signal to cut off the house water.

Cannon Water Detector Switch and House Water Leak Prevention

However, the quick operating solenoid valve created a bad water hammer.

I came up with a quick solution before taking out my torch, etc.

For $5 I bought a hose bib Y with SS ball valves made to control 2 hoses.

I put a vacuum break and the hose on one part as normal.

On the other part I screwed on a female hose to male 1/2 NPT adapter, a 1/2 female NPT to 1/2 PVC L, a 10 vertical piece of 1/2" PVC, and I capped it off.

(1/2" PVC is rated at 600 psi.)

The hammer reducer is adjacent to the solenoid valve.

Works perfectly, not a peep.

Should the air in the dead end pipe get absorbed, I would turn off the hose bib and drain it.

When I get a chance I might solder a 1/2" copper T to the hose bib, etc.

You may think you invented this idea but it's been around for years and can be bought right over the counter or on the net.

Interesting.

Please show us a link that sells a hammer eliminator that screws onto a hose bib and can be instantly emptied. No cutting or soldering.

It would be news to me and much appreciated.

I've got something similar but it doesn't work that great (still hammers when the valve turns off). I think I'll give your idea a try, thanks!
