What is this?

[Jaysun]

A metal piece on my sprinkler system busted (see pic below). Seems easy enough to replace myself, but I'm not sure exactly what I'm looking for (I saw lots of similar items on the Lowe's website, but nothing that looks exactly the same). Can someone point me in the right direction?

Thanks,
Jason

Thanks. I've found it, both on Amazon and on the manufacturer's website.

Are you planning on replacing the entire unit or just the cracked ball valve with the test connection.
Don't know how long you have lived there but I think you should know that this is a testable device, which typically requires periodic testing by licensed tester. The water purveyor is typically required to keep records of all of these testable devices to ensure that they are tested based on your local requirements.
Having said that, I am somewhat doubtful that this level of device(High hazard protection) is actually required. The average sprinkler system typically requires a Pressure vacuum breakers (PVB), which typically does not require testing.
I would inquire as to what type of device your water purveyor requires on a sprinkler system. It may save you money in the future.

EDIT: By the way, an RPZ(Reduce Pressure Backflow Preventor and it's associated piping, should not be exposed to freezing temperatures while water is in them.

the three test ports to the left of that ball valve would be the "test ports" I would reinstall that exact valve just incase the city or town needs it there for any reason

im not sure on the rules for where you are, but in BC where I am.. I strongly advise not touching it and having a backflow certified plumber come out, as here you could get your self in some serious trouble

If it was me, I would find out exactly what is required and/or not required by the authorities having jurisdiction, first. How you do that is up to you.
Once you know exactly what you're dealing with, you'll know what to do.

You could start off by letting use know you're location and someone may already know the actual requirements or could find them out.

When that type of device is installed, it is typically required that the authorities having jurisdiction are made aware of it, for their recording, and to see that it is tested by a certified tester, based on a predetermined schedule(commonly annually).

The thing is, if you haven't been contacted by the water purveyor and you have lived there for more than a year, chances are they are not aware of it.

And these things typically cost in the neighborhood of a $125 to $150 to have tested. At least in my neck of the woods, some 8 years or so ago.

Thanks, everyone! I'm in Lexington, KY. Bought this house in October and knew I needed to drain the lines before winter, but the first freeze caught us by surprise while we were out of state for a few weeks in early November, and this was the result (turned the water off all winter and waited for spring weather to repair it).
