SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

I have a rainbird controller and Febco 765-1 PVD. Controller seems to be working fine. I had a broken poppet that I replaced with a Blue Herron Bonnet & Poppet. Things seemed to work fine for a couple days now nothing. I later noticed this on the Febco 765-100 1inch PVD Backflow preventer. Could this be the issue of my sprinkler system not working.

Well..... Since that didn't really answer my question, thanks for the smart ass unhelpful comment Captain Obvious! But my original question was could this crack affect my system from not working. Not about winterizing or how to prevent this from happening.

As I'm a first time home owner with a builder installed sprinkler system, no instruction manual was given to me regarding the PVD or any instructions as how to winterize the PVD. I had no previous experience with sprinkler systems before buying this house, so forgive me for not knowing about winterizing.

But since hindsight is 20/20 can someone answer my question. As Mr Wetboot aptly pointed out, with the inlet valve open would this crack affect my overall system from not working. I know the PVD has to be replaced, but I'm trying to determine if this is the cause of my entire system not working or something else. As the inlet valve is opened, obviously water sprays out of this crack, but once fully open there doesn't seem to be a noticeable leak from the crack. I'm asking if this crack causes enough of a pressure loss that it's preventing my whole system from working.

Again, I know the PVD needs to be replaced because I didn't winterize it. I'm trying to figure out if I need to be prepared to fix a larger problem with my system than just this broken PVD. Also, before Captain Obvious answers with more obvious statements. I have walked my property & there are no other broken pipes leaking or any other visible problems with the system. Oh and no there is no rain sensor. And, yes I have done the troubleshooting with the actual controller.

Thanks

Ok seriously.... It's obvious I'm no sprinkler geek.

You don't need to be a mind reader but at least read!!! Can THIS CRACK CAUSE AN ISSUE WITH THE WHOLE SYSTEM????? THAT'S 1 question, not even 2 let alone 20!
That's all I'm asking?!?!?! Who needs to be a mind reader, just have high school level comprehension? CAN THIS CRACK affect the whole system?!?!?! Like I stated I want to be prepared for something more major when I call a repair guy if THIS CRACK is not the only thing wrong. Though I didn't point it out in clear sprinkler lingo, I DO NOT KNOW WHERE ZONE VALVES are, I figured the sprinkler GODS would understand when I said "I have no experience with sprinkler systems". But again ALL I'M ASKING IS ABOUT THIS CRACK THAT I TOOK A PICTURE OF! Simple yes or no! So let me be perfectly clear. I don't care about anything else that could be wrong, I just want to know about this crack. Can this crack cause the whole issue. If not, then I know there is something else.
