I have this Rain Bird sprinkler system that I haven't used yet, and am trying to figure out. Last winter, I follwed the instructions left by the PO of the house to winterize the system, so I should have been okay there. He didn't say to remove the Pressure Vacuum Breaker, but I see in the manual I just downloaded that I probably should have.
After mowing today, I closed the valves that I remembered opening to let the system drain for winter, then I turned the water to the system on. Pretty much right away, water started coming out from the top of the Pressure Vacuum Breaker thing, so I'm thinking there may be a problem. I turned the water off and the leak stopped, so that's where I am right now.
Here's what the breaker valve looks like:

It looks like I can get a new one for around $100. Does anyone service these valves? Maybe I just need seals or something. Maybe the problem isn't even in the unit, I don't know for sure. I left a message with one of the lawn service places, but I'd like to do everything myself if I can.
