setback
I figured it was inevitable, and indeed, it has now happened: putting in another plant, I punctured the sprinkler pipe with the pitchfork. It's tough here, operating without having any idea where that pipe is; I mean, no idea until I run into it with the shovel. I don't even know where all of the sprinkler heads are, so disguised are they when not actively sprinkling. Anyways, I hit the pipe the other day and put a couple holes in it. The sprinklers still work, but the section I holed shows rather less water pressure than would be ideal; besides, of course, the jet of water that somes out of the ground where the break is. I wouldn't have even realized that there was a problem, since now that the sprinker system is functional I don't pay it particularly close attention, but for the tunnel that the escaping water carved to the surface. Did I mention that the system operates under considerable pressure? I made some rudimentary repairs, so we can at least run things again, but further work is still needed.
