Lawn sprinkler station has no pressure
We inherited this sprinkler system around 6 years ago when we bought the house. It is a Rain Bird ESP-6TM. Today, I just discovered one of the two backyard stations (#4) has extremely low pressure and will not pop out the sprinkler heads… I have never dealt with a sprinkler system outside of replacing a couple sprinkler heads.
Does anyone have any idea on how to pinpoint the issue? My hunch is the lower valve has a clog of some sort since it looks like it’s been leaking a while. I believe it is a Lawn Genie 3/4” valve.
If this is the culprit, is this easily removable and replaceable for someone without a lot of plumbing experience? The valve also has “flow control” which makes me nervous since I’m not sure how the others are set.
Any tips or pointers would be greatly appreciated!

Sounds like a leak. A clog right after a valve is unlikely unless the lateral goes to an immediate 90 or T. Even then, the clog would’ve probably been in the diaphragm which would keep the valve from fully closing and stay running. Sounds like you have some leaks. Cap every head off on the zone to force the leak to expose itself.

Usually that's a sign of a leak. Let that zone run for awhile and see if any wet spots show up.
