I had made note of the excessive rot in the fence panel I am working on now. In the last post, Repair to Renew I made note of the advanced level of rot in this section. The bottom runner was rotten. Well there is usually a reason, and it is here in the same area. The subterranean sprinkler...
The riser is threaded onto the supply pipe at an angle. This is the effect of making assumptions, and making blind connections. The pop-up head that was in this place malfunctioned years ago. I don't remember exactly what happened. It could have been that one of the dogs decided to chew it up, I don't remember.
I made an assumption that the supply pipe was rigid. I unscrewed the pop-up head, and then screwed in a riser to make a fixed head. It must have felt right at the time, and tested OK, but I didn't notice the massive subterranean supply pipe leak. So, over the years I have noticed a inexplicable flow in that area on the property line, and assumed, again, that it was not my system, LOL! Hindsight...
