On my way out on Friday I discovered an irrigation leak on #3 Greywalls.  The pipe malfunction took place to the left of the green.  The pipe blow out because the installer was very messy with pipe primer causing an area of weakness (as seen in bottom photo).  The pipe blew on the bottom side and bored a hole (middle photo) deeper than a shovel.  After around 18,000 gallons of water filled the approach like a water bed, it began to discharge out of the root zone 35 yards away.  I purchased the parts Friday night and made the repair Sat. morning.
