Method of installing A1
drip line |
|
Below grade close loop
installation of A1 PC drip line |
- Where it is feasible excavate
the entire area to the depth recommended for the layout of the
drip line, or trench a ditch 4" to 5" deep for placing
A1 drip line starting 2" to 4" from sidewalk or curb.
- Plant all large trees and shrubs,
10 gallons and up.
- Install control wires and lay
them to the side or below main line.
- Install remote control valve
or battery operated controller with a filter and pressure regulator
below grade. See overview
of system requirements
- Install supply line and connect
to electric remote control valve or battery operated controller.
- Flush and test supply line.
- Place A1 PC drip line at the
row spacing recommended and to a depth of 4" (see spacing and flow rates) and cap off all
openings to prevent dirt entering the drip line by using model
16-021 hose end.
- At the end of each A1 drip line
run, trench a large opening in the ground to connect the A1 drip
line to the PVC pipe or poly pipe supply line to form a closed
loop.
- Use PVC insert model 24-008
to connect A1 drip line to a PVC supply line by utilizing SCH
40 slip tee or compression tee or model 24-003 to connect to
poly pipe.
- Install air/vacuum relief valve
inside 6" irrigation box at the highest elevation point
within the zone.
- Install a flush valve or ball
valve inside 6" irrigation box at the end of the supply
line.
- Plant all small sized shrubs
and flowers.
- Remove all rocks from excavated
area and do not backfill the trenches with rocks to prevent damage
to the drip line.
- Flush and test the entire system
and check all connections and A1 drip line for leaks.
- Inspect and replace leaking
and damaged parts.
- Test the system with continuous
pressure for two hours.
- Cover the entire area to a finish
grade with 4" of mulch.
- Instruct personnel on the proper
operation and maintenance.
