Multiple concentric rings provide irrigation coverage extending from the root ball to the projected tree canopy following manufacturer guidelines and specifications. Tie-down stakes are placed every three feet in sand, four feet in loam, and five feet in clay. Fittings experiencing a change of direction such as tees or elbows require tie-down stakes on each leg of the transition.
NOTES: 1. INSTALL MULTIPLE RINGS AS REQUIRED TO PROVIDE IRRIGATION COVERAGE FROM ROOT BALL TO PROJECTED TREE CANOPY. REFER TO RAIN BIRD DESIGN GUIDELINES AND SPECIFICATIONS FOR RECOMMENDED SPACING BETWEEN RINGS. 2. PLACE TIE DOWN STAKES EVERY THREE FEET IN SAND, F0UR FEET IN LOAM, AND FIVE FEET IN CLAY. 3. AT FITTINGS WHERE THERE IS A CHANGE OF DIRECTION SUCH AS TEES OR ELBOWS, USE TIE-DOWN STAKES ON EACH LEG OF THE CHANGE OF DIRECTION.
