installation
Begin your installation at the water source by attaching the backflow preventer (1) to your faucet,
then attach the 25 PSI preset pressure regulator (2) to the backflow preventer (3). Connect the
hose adapter to your pressure regulator and insert the poly tubing to the adapter. If you wish to
automate the system, you can use a DIG battery operated controller (Model 9001D or 9001EZ)
available in a store near you.
Next, lay down your 1/2 in. poly tubing. If you plan to leave it above the ground, allow the poly
tubing to sit in the sun before installation, making it easier to work with. Use stake to secure poly
tubing to the ground. If you are burying the poly tubing, dig a trench about 6 in. from the roots of
your plants. A shallow trench, 5-8 in. deep is all that is needed to keep the poly tubing safe from
cultivation practices. Do not bury the end of the poly tubing, allow it to remain on the surface for
periodic flushing.
TYPICAL INSTALLATION
Connecting and installing 1/2 in. fittings:
To install your 1/2 in. fittings, cut the poly tubing with a hand pruner, being careful to keep dirt from entering the line. Push
the poly tubing into the fitting by wiggling it as you apply force
Connecting 1/4 in. fittings:
To install your 1/4 in. barbs, tees or elbows,
push the microtube over each of the barbed
ends. Soaking the microtube in warm water will
make it softer and the fittings easier to install.

Installing drippers to 1/4 in. micro tube:
For plants far from the poly tubing, first insert a 1/4 in. barb or tee into one end of the 1/4 in. microtube, then insert the barb
into the punched hole in the 1/2 in. poly tubing and run the microtube to the plant. Next insert the barbed inlet of the dripper
into the end of the microtube and secure with a stake.
INITIAL SYSTEM START-UP
Before turning the system on for the first time, leave all 1/2 in. tubing ends open and turn your water on and allow it to run
freely for a few minutes. This will flush out any dirt that may be in the line.
Close the end of the line by using a “figure 8” hose end or end cap. Check to see the drippers are operating correctly and
that no leakage is occurring.
Repairing or Plugging a Hole on 1/2 in. Poly Tubing:
If leakage occurs on 1/2 in. tubing at the base of a dripper, remove the dripper and insert a goof plug to close the hole and
reinsert the dripper in a different place.
Watering
Watering Recommendation:
Example: For shrubs up to 3-5 feet in diameter, we recommend a 3-4 GPH in full sun. The recommended flow rate can be
achieved using 3-4, 1-GPH drip emitters spaced around the tree or 2, 2-GPH drip emitters. These guidelines are suitable for
most areas and soils.
Note: Plants larger than 2 feet in diameter should have more than 1-drip emitter per plant.
Watering Time:
Run the system 45 minutes to 2 hours every 3-5 days, depending on your location (cool to warm) and soil type. After a week
check the soil, the health of the plants, and adjust the watering time as needed.
Using the punch:
To insert drippers, microsprinklers and 1/4 in. fittings
into 1/2 in. line, hold the line in one hand and apply just
enough pressure with the punch to puncture tubing.
Installing drippers to 1/2 in. poly tubing:
Drippers are installed by punching a hole in 1/2 in.
poly tubing and snapping the larger barbed side
in. If your tubing is buried, the drippers should
always be located above the ground. This is
achieved by inserting a 1/4 in. barb or tee into the
poly tubing and running 1/4 in. microtube to the
surface where the dripper is installed.
