Today we had an unusually warm day and was checking the sprinklers. I found that none of the zones controlled by the box in the backyard work. I'm from an area where sprinklers aren't typically used so I'm really unfamiliar with them. I was reading about valves leaking and the danger to solenoids. Any direction you experts can provide would be greatly appreciated.

Thank you!

Don't know how old your system is or if a contractor installed it and it is under warranty, but here is what I would do assuming it is an old system.
1. Dig out the valve box and find the leaking valve.
2. Replace leaking valve.
3. Deepen the the valve box area and place gravel in the bottom of the valve box equal the original level.
4. Replace all the solenoid connections at the valves with waterproof screw-on connectors.
5. Check connections are solid at controller.
6. If the controller is older than 6 years old, replace the controller.

or pay someone to do it. It will be worth the effort or money in the future. JMHO Aloha

Any further thoughts given the new information?

Any idea what kind of cost I'd be looking at with your suggestions above (if I did it myself)? Yes, it is an older system. I don't know how old.
