I've seen him hook up the compressor somewhere on the back low but I
don't know where. I was hoping that someone would be able to tell me
where to attach it and if there is anything else special I would need
to do.

Here are some pictures of my backflow:

Thanks!

Well, you would first Google Wilkins Zurn to find the manufacturer's
website. *Then you would use the search tool on that website to find the
975XL backflow preventer. *Finally you would download the Installation,
Testing, and Maintenance Instructions. *The diagrams provided would then
clearly indicate that you can attach your compressor to Test Cock #4.
You would, of course, also want to know what pressure is acceptable to
use by referring to the specification page.

Or you could just pay the guy $70 to do the work for you. *Heck, for $50
bucks I'll send you the pdf since I already did the work to find the
little bit of information for you.

I read the pdf but didn't see anything about winterizing. How did you
figure it out? Do I need to open test cock #4 before I attch the
compressor? What about any other test cocks?
