Added a zone for a 10,000.00 Tree that was lifted over the house and planted in the backyard. I'm using RB XPCN fulls for the watering. Anyway the landscapers rerouted the section line around the tree and left out the two fulls that were in that area. I had a bag of 1" blazing saddles from a DIA meeting sitting in my garage from a year ago. So I figured I'd give them a shot. Made for a fast install. No leaks. They stick up a little high but swing jointing the head down was no problem. I can see how these could really speed up system renovation work.
