Hi
one of my sprinklers is always flooded, its the lowest one in the system.
So I assume there's water leaking from the valve, into the system and its
collecting there, but I'm not sure what I would need to look for at the
valve.
thank in advance for any help

It might be leaking between the control valve and the head too, unless it's
flooded around the valve box, no?
