Was digging to plant a tree and saw this black tube thingy. Not sure if it's a cable line, a phone line or a sprinkler line? Can't be electrical cable since it's barely 12 inches underground.
@vbx, may not be official electrical cable, but the previous owner of your house may have laid a cable to garden lights etc etc. I would investigate where it leads, 'but on NO account cut it'.
Been to hot for me to dig up. It's a strange line. The sprinklers lines I have are all PVC. The mods I've done to move the sprinkler head, I used a rainbird line which has a green line running across it and made of a used tire like rubber. This is pretty thin plastic. So this is weird. I'll have to see where it leads to.
