Procedures
Special Considerations for Subsurface Installations
1. The typical recommended pipe depth for dripline is 4” below
finished grade.
2. For turf areas where aerification is part of normal maintenance
operations, tubing must be buried below the reach of aerification
equipment.
3. Use 710 Series compression fittings for all dripline connections to
ensure the integrity of the connection. Use ¼-inch barbed
fittings for microline connections.
4. It is imperative that DL2000 dripline is installed at a uniform depth
and width according to specifications.
Dripline can be installed using one of the following methods:
5. When possible, pressure test the system before covering trenches or,
when plowing, pre-test for leaks prior to planting.

■ Installation Procedures
INSERTION METHOD ADVANTAGES DISADVANTAGES
Hand trenching or backfilling – Handles severe slopes and
confined areas
– Uniform depth
– Slow
– Labor intensive
– Disrupts existing turf and
ground
Oscillating or vibrating plow
(cable or pipe pulling type)
– Fast in small-to-medium
installations
– Minimal ground
disturbance
– No need to backfill the
trench
– Depth must be monitored
closely
– Cannot use on steeper
slopes (20%)
– Requires practice to set and
operate adequately
– Tends to “stretch” pipe
Trenching machine – Faster than hand trenching
– May use 1” blade for most
installations
– Uniform depth
– Slower, requires labor
– Disrupts surface of existing
turf
– Backfill required
Tractor-mounted 3-point
hitch insertion implement
– Fastest method, up to four
plow attachments with reels
– Packer roller compacts soil
over pipe
– Only suitable for areas large
enough to maneuver a
small tractor
