sprinkler-systemvalve
Outside I have a leaky secondary water valve that seems to overfill whenever my secondary water is turned off. I don't have the slightest clue of how to replace this and would rather learn how to do it myself instead of hiring a landscaper to do a few hours of work.
Can somebody recommend the best way for approaching this?
Over time the surface of the plastic part that joins the tank to the bowl can get tiny defects in it that prevent the flapper from making a good seal. As Jeff suggests, you could try cleaning that part, or just replace it.
I'm not sure who the idiot was who put this down that hole, but it was pretty firmly lodged in there. I cut off a bit more of the PVC and was able to get my trusty pry bar in the notch and turn it. After about three quarters of a turn the stupid thing came out. And sure enough, there was a regular stop and waste down there underneath whatever the heck this is.

Without seeing the actual valve type and piping arrangement it will be very difficult for anyone to tell you what you are in for.
One thing I know for sure: step #1 is digging it up! Once it is exposed you (and our on-line community) will have a much better idea of needed repair work, if you add pictures to your post.
Questions: 1) Is it a continual leak that keeps the area flooded like in the picture? If so, you will need to effect a positive shut off upstream and let the water soak in or dry up before excavating. You will likely need to do this anyway to proceed with the repair or replacement.
Judging by the type of handle I see in your picture, I suspect it might be a valve like this:
If it is a brass valve like this, they are usually fairly simple to repair. replacement is not always as easy.
