Is the poly connected to the valve directly or is it 3/4" PVC past the

Well, I don't really know.

All I know, working backward, is that for "most" of the 300 foot
run, there is a 1/2" and a 5/8" poly pipe feeding the oleander:

Every once in a while, you can see them both on the surface:

As those two poly tubes get within 30 or 40 feet of the irrigation
valves, they suddenly pop up out of ground (I had put the garden
hose connections on):

I didn't dig up the irrigation valve, so, I have no idea how it's
hooked up, but, the 5/8" poly tubing which was broken at this point,
appears to continue along the oleander until it gets near the irrigation
valve. A foot away from the valve, it dives down, presumably to the
valve (which works, and sends water through the broken tubing):

Note: I dug around for a half hour looking for where the 1/2" poly
tubing connects to the irrigation system - and finally gave up on that
endeavor. Also, I can't tell if there is a pressure regulator on the
valve itself, as it might be buried, for all I know.

I guess I should pick up a pressure tester for garden equipment, to
be sure.
