INSTALLATION INSTRUCTIONS
Landscape Drip
Watering System
Model G77AS
Begin your installation at the water source
by attaching the backflow preventer to
your faucet , then attach the 25-PSI preset
pressure regulator to the backflow preventer.
Connect the poly tubing to the hose adapter
and attach it to the pressure regulator.
If you wish to automate the system, you can use
a DIG battery or solar operated controller (model
B09D/B092A or EVO 100), available online or in a
store near you.
Next, lay down your 1/2” poly tubing. If you plan
to leave it above the ground, allow the poly
tubing to sit in the sun before installation; this
will make it easier to work with. Use 1/2” holder
stakes to secure the poly tubing to the soil.

Connecting and installing 1/2” ttings:
To install your 1/2” ttings, cut the poly tubing
with a hand pruner or scissors, 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” ttings:
1. Force a barb or tee into the end of the 1/4”
micro tubing by pushing it in while moving it
from side to side.
To connect the end of 1/4” micro tubing to 1/2”
poly tubing:
2. Punch a hole in the 1/2” poly tubing with the
punch tool.
3. Insert the open side of the barb or tee into
the hole in the 1/2” poly tubing.
TIP: To ease installation, warm the ends of the
micro tubing in a cup of hot tap water for 20
seconds prior to barb installation.
Installing drippers to 1/2” poly tubing:
Drippers are installed by punching a hole
into 1/2” poly tubing and snapping the larger
barbed side of the dripper in. If your poly tubing
is buried, the drippers should always be placed
above the ground using 1/4” micro tubing.
Installing drippers to 1/4” micro tubing:
For plants far from the 1/2” poly tubing, or if
the poly tubing is buried, rst insert a 1/4” barb
or tee into one end of the 1/4” micro tubing,
then insert the barb or tee into the punched
hole in the 1/2” poly tubing and run the micro
tubing to the plant. Next, insert the barbed inlet
of a dripper into the end of the micro tubing
and secure it with a stake.
Initial system start-up
Before turning the system on for the rst time,
leave all 1/2” tubing ends open, turn your water
on and allow it to run freely for a few minutes.
This will ush out any dirt or debris that may be
in the line.
Close the end of the line by using a “gure 8”
hose end or end cap. Turn the water on again
and check to see that the drippers and micro
sprinklers are operating correctly and that no
leakage is occurring.
Use stakes to secure the poly tubing to the
ground.
Repairing or plugging a hole on
1/2” poly tubing:
If leakage occurs on 1/2” tubing at the base of a
dripper or micro sprinkler, remove that dripper/
micro sprinkler and insert a goof plug to close the
hole, then reinsert the dripper or micro sprinkler in a
different place.
WATERING SCHEDULE
Open the faucet for 45 minutes to one hour every two to three days, depending on your location, weather
and soil type. Faster draining, lighter soils will need to be irrigated more frequently than heavy, soild soils
with high clay content. After a few days, check the soil and the health of the plants, and adjust the watering
schedule as needed. If you have an irrigation controller and additional time is required, adjust the irrigation
controller program with a longer watering duration and/or additional start times.
