The neighbor's back flow preventer was stolen too.PS. Maybe some thug was prowling around your property and you came home so he tripped on it while running away, breaking it off, and it went flying into the neighbor's yard? ;-)

I wonder why. Isn't the whole idea that this device prevents backflow no matter where they are located? Our water company just put them in for all of us that had sprinkler systems last year and they simply put them at the front of the meter.And I think it has to be a certain distance above your sprinkler heads by code... <_<
There is a whole business of winterizing backflow preventers around here. People charge $75 to $100 to shut off and purge the water out of the system with a compressor. Once purged, the valves on the backflow preventer are opened, and the body is usually loosened enough that any remaining water will not damage it. I winterize the system myself, and look what it got me.Wouldn't this thing freeze being above ground?

Reviving this thread, what compressor do you use, CORT? I'm also in TN. Newly installed irrigation system, last winterization came 'free' with install.
I watched him clear the lines. He told me a compressor with 130 psi is required (his was a giant compressor, on a trailor, pulled behind a truck).
I found plenty of compressor options that go above 130 psi, at Lowes and HD, but I ran into a roadblock with 'CFM'. What is the cubic feet per minute rating of your compressor?
FYI, irrigation company removed my backflow preventer, and put it in my garage for the winter.
Thanks, Cort.

I'm in FL now, so I don't need to winterize. When I was in NY, I always blew out my system myself, and used a 1 HP Craftsman portable compressor that is usually used for tire inflation. It didn't have a tank and did 125 PSI. It took a lot longer than the big compressors, but it did the job. You just let each zone run until air is blowing out.
Here's one with a tank that should do the job: Craftsman compressor for $99
