Upon turning on my water supply to my sprinkler system this year, the connection between the Backflow Preventer and the Sprinkler System is leaking. I installed the entire sprinkler system myself with the exception of this assembly; our local landscaper tied into main line and installed this portion; so I'm not sure how it all connected together.
My question...is this a typical DIY? Where do I start? Will the PVC need to be cut? Thank you for any advice.
