Started last part of micro-spray conversion in front of a kindergarten building today. This is an area that we cut the drip away from the office planters. Set a new valve to handle it as a completely new zone. The guys that designed and installed the original system 15 years ago were kind enough to leave us plenty of extra wire for this task. (Breaking arm patting self on back.) Only problem encountered was the old fart (me) trying to cautiously dig around a tree root in order to cut it out of the way with loppers when he hit the 2" main line spur with the pointiest part of the trenching shovel. Boy did I get a bath! Monday is a non-school attendance day so we're hoping to finish up then. Depends on whether we start breaking out concrete on a main line repair at another site.
