If you have a leak somewhere there has got to be a rather large soggy

Can't find any, it could be possible that since I live in Florida, the
soil below 1-2 feet is sandy, and could be soaking it up?

I've never had one on any of my irrigation systems, but there is/can
be what's called a _positive drain valve_ on the end of the zones.
Essentially, when the valve shuts off the remaining water drains to a
sand pit. The prevents freezing of the pipes.

If you have such a PDV valve and have a bad diaphragm / solenoid on
the zone valve, water would leak to ground.

(Not an expert..)


Are the sprinkler valves electric? Can they be turned off manually
(individually)?

Hunter sprinkler system with a Rain Bird controller

(I assume you cut off water to the sprinkler valve manifold) that the
"leak" is a faulty sprinkler valve not a line failure.

I have checked all of the valves (had to replace one solenoid) and
they are not filling up with water when running. I have only turned
off the rain bird control, not the incoming water at the backflow
preventer (Two knobs, 1 for interior & 1 for exterior)

Are some the heads in one of the zones wet constantly?

No, even with the main still on and RB turned off
