Irrigation System Details for Dripline Flush Point, Pop-Up Sprinkler, and Air Relief Valves

About this detail

The irrigation details illustrate underground valve boxes, pop-up sprinklers, and air vacuum relief valves connected to schedule 40 PVC piping and dripline tubing. The assemblies feature six-inch round plastic valve boxes set over six-inch deep pea gravel sumps supported by common bricks. Components include one-half inch schedule 40 threaded ball valves, male adapters, PVC nipples, couplings, Toro pop-up sprinklers with side inlets and precision nozzles, Toro DL2000 tubing, and Toro air vacuum relief valves. Notes specify allowing a minimum of PVC hose inside valve boxes to direct flushed water outside, using one air relief valve for every seven gallons per minute per zone located at high points, and heat-branding lids with specific text characters.
