re: Winterized backflow preventer-question

Yeah I just went and I don't think it's in the meter box. Can't find it for the life of me. Have no basement, so not there. Not by sprinkler system controls, not by BFP

Best I can recommend is to trace the inlet side of the BFP backwards until you are at the main line. If no valve, your guy didn't install one.
In which case, close the inlet side valve, leave the others open and you should be ok if you wrap the inlet side piping in towels.
Where are you located and what kind freezing do you expect to experience?

Located near Shreveport. Low of 24 tonight and possibly in the teens later this week. Already have it wrapped.

You're probably good with the wrap.
You could also either crack the inlet side open just slightly enough for a drip of water to keep water moving. That or put a garbage bag over the whole thing and run an extension cord and light bulb out there.

I didn't drain mine last year and the whole thing cracked (all internal stuff). I'm in Mandeville.

I never drain my sprinkler system. I'm in DFW and we had quite a few days below freezing last year after an ice storm and didn't have any problems. I wouldn't worry about it.

I've never drained mine or wrapped pipes. It got me last year finally.

Best to be safe than sorry though. And if not this time, sooner or later you'll need to know where the cut off is so effort surely worthy.

I am not familiar with sprinkler systems, but I am betting that the main supply valve to your sprinkler is somewhere between your water meter and where the water line enters your house...just draw a straight line between your meter and your house and look around the house for an above-ground valve...

All backflow preventers have a valve on the inlet and outlet side. If it's the type for a lawn sprinkler system turn off the valve on the inlet side (there will be an arrow on the valve body) then you should be able to insert a flat head screwdriver and open the test ports for draining.
post a picture of it please.

no they don't. pipes break when the water inside freezes and expands.
OP you are going to have to traces your line back to the main supply, there SHOULD be a valve there, if not there wasn't one installed.
You could just let one sprinkler zone run and enjoy the ice show, or you could just setup a small tent over it with a tarp and run a light underneath it.
