12 Zones, 4 Control Valves, one zone not working

The system was installed about 10 years ago, it is on an Orbit Control Panel. I replaced a control valve about 6 weeks ago when 3 zones had lost pressure. I pulled the top of a head and there was muddy water in the head. I turned the zone and could not find a leak in any of the zone head points. There is how ever water standing in the control valve box. any thoughts

Three zones lost pressure?
Why replace one valve?
What happened on the other 2 zones?
Sounds like a leak.
