Edit: Success. Well, not quite. It sprung a leak on one of the joints. So how exactly do you splice a short piece of PVC pipe? You have to put those couplings on each end which means it's too long to go in between the gap of the missing pipe that's been cut out.Ok, that's too hard to explain. Someone knows what I'm talking about and feels my pain.
Edit: Success. After one additional splice, it's holding.
Edit: You guys are doing some CSI work on the two photos. The first one was taken on the front side of the fence (that's a gap in a gate opening, not falling down.) The second was taken on the other side of the fence after significantly more digging. And, yes, even the front side has now been weedeated (sp.)
