All pipe and communication wire under hard surfaces shall be placed in separate sleeving. All wire shall run, whenever possible with the mainline. 11. All lateral zones shall be connected to the mainline with PVC pipe and sized as follows: 1" Class 200=0-30 gpm 12. All sprinkler heads shall be set perpendicular and flush to finish grade and with a clearance of 2" (min.) from the edge of any hardscape unless otherwise specified. 13. Check valves shall be installed on all irrigation heads in areas where finish grade exceeds 4:1, where post valve shutoff draining of the irrigation head occurs or as directed by the Owner's representative. 14. All sprinkler heads and valves shall be flushed and adjusted for optimum coverage with minimum over spray on hardscapes or buildings. 15. Provide pressure compensating screens and/or 1 nozzles to reduce or eliminate over spray onto walks, streets, or other areas directed by the Owner's authorized representative. 16.
