Sprinkler System - New Back flow preventer

[DenverGP]

When you get to the actual piping portion of the backflow preventer - you might want to consider using Shark Bite type connectors (there are several brands out there).

I use the same thing on mine, been set up with those the past 3 years, no issues at all with it coming loose or failing to seal.

I've had my Febco 1" PVB setup with them for 3-4 years now too and no issues. They may have even been the (crappier?) ones from Lowes. They are both on the vertical pipes in/out side so it's simple to pull and install every year. I make sure the pipes are cleaned up first. Damn old bevel unions always leaked on me, and I've had ball valves crack even after blow out.
