Here's a pic from last Tuesday on a main line leak we were repairing when my back pain got so severe that I had to seek medical attention. The SCH 80 nipple was installed fairly loose... thus creating a leak and swampy area needing attention. It was so loose where the nipple enters the valve that the valve could be turned using one finger. (I took video of the looseness but it's too large to post here.) Why they used a saddle clamp instead of a glued 4" x 4" x 2" PVC tee is beyond me. This now makes approximately 25 leaks/breaks on our three newest elementary school sites with systems that are three years old or less.
