Hi everyone I'm new to this list and am really in need of help with our irrigation system. Just started using it a few weeks ago and my wife noticed this week that the vacuum pressure breaker is leaking.I'm trying to save a call to our installer. Anyway all the zones have normal pressure. The breaker leaks when the intake valve is both closed and opened.
I don't know if it's relevant but both the turn controls for both the intake and outtake ball valves are pretty rusty. I can't turn either by hand have to use a pair of pliers to turn. I also noticed the canopy is cracked around one of the screw holes.
I opened the thing today removing the bonnet,spring, and poppet. Could not get the spider assembly out. I'm not sure what to look for with these inner parts but they seem fine.
This breaker is a Wilkins 720A installed in 2003. I have it winterized every year;last year we did it a little later sometime in June.
Any advice is appreciated. From what I've seen on the internet I could order and replace a whole new valve for less than paying for a service call.When do you know if replacing parts is the way to go?
Thanks for your help
