ABOUT YOUR G77AS KIT
Let your landscape thrive with this complete drip watering kit that connects to any outdoor faucet.The
G77AS starter kit includes DIG’s pressure compensating drippers and contains all the parts needed to
irrigate up to 150 square feet. Use these guidelines to design and install an efcient low-volume irrigation
system that conserves water and promotes a healthy environment.
LAY
INSTALLATION
This kit can be connected into a 3/4″faucet/spigot or at the end of a garden hose. If a faucet is not
adjacent to the garden or to the location of the installation, you may extend from the faucet using a garden
hose or an additional length of 1/2″drip tubing (model B35 for 50′or B36 for 100′).
To start the installation, the backow device should be mounted directly to the faucet Please make sure to
add the 25-PSI pressure regulator (included) after the backow preventer. The pressure regulator is used
to lower the incoming pressure from the faucet to the recommended operating pressure of 25 PSI, which is
within the range of operating pressures for drip irrigation or micro-sprinkler systems.

Faucet connection:
Begin the installation at the water source by attaching
the backow preventer to your faucet , and then
attach the 25-PSI preset pressure regulator to the
backow preventer. Connect the poly tubing to the
3/4″swivel adapter and attach it to the pressure
regulator by turning “clockwise” until hand tight.
If you wish to automate the system, please select
a DIG battery or solar powered timer (model B09D,
B092A or EVO100), available online or in a store
near you.
Drip tubing layout:
Before installing the 1/2″poly tubing, uncoil the roll
and lay it out in direct sunlight (if possible) for 30
to 40 minutes. This will make it more pliable and
easier to work into the compression ttings during
installation.
Lay out the 1/2″poly tubing and run it next to as
many plants as possible. Secure the drip tubing to the
soil with the 1/2″drip tubing stakes. Install the poly
tubing in a gentle S curve to allow for contraction
at low to high temperatures.
Connect the 1/2″ drip ttings
Use 1/2″ tees (part #C35) and elbows (part #C36)
throughout the layout as needed. To install the 1/2″
compression ttings, cut the poly tubing with a hand
pruner, being careful to keep dirt from entering
the line. Hold the tting in one hand and the poly
tubing in the other and force the poly tubing into the
compression tting by moving it from side to side.
Note: Open the faucet and ush out the poly drip tubing
through the ends before installing the drip emitters.
Drip emitter installation:
The drip emitters can be installed along the poly
tubing at varying or specic spacings, depending on
the layout of the plants. To ensure high uniformity,
take care not to exceed the recommendations
provided in the kit specications.
To install the drip emitters, use one or both of the
two options:
Option 1:
Installing the drip emitters into the 1/2″poly tubing
Insert the drip emitters directly into the 1/2″tubing:
Punch a hole into the side of the poly tubing using the
small punch (part #D44). Snap the barbed side of the
drip emitter into the hole after the lines have been
ushed.

• Micro tubing length and size: 50′x 1/4″
• Total ow rate for this kit: 32 GPH (.53 GPM)
Option 2:
Installing the drip emitters into the 1/4″micro tubing
Extend the drip emitters using 1/4″micro tubing to reach
plants that are not near the 1/2″poly tubing: First, run a
length of micro tubing from the 1/2″poly tubing to the
plant and cut it. Then, insert a 1/4″barbed connector
(part #H80A) into the micro tubing. Punch a hole into the
1/2″poly tubing and insert the 1/4″barb into the poly
tubing. At the other end of the micro tubing, insert the
barbed side of the drip emitter after the lines have been
ushed. Add a stabilizer stake and secure to the ground.
Use the 1/4″barbed valve for manual control of individual
line of micro tubing.
Initial system start-up
Turn the water on again and ush the line[s]; this will
ush out any dirt or debris that may be in the line[s]. Close
the end of the poly tubing with the gure "8" hose end
(part #F68B).
Test and inspect the system to identify if there are any
leaks in the drip tubing laterals. If there are any leaks from
the barbed ttings or drip emitters, remove the ttings
or drip emitters and insert a goof plug to close the hole.
Reinsert the barb ttings or drip emitters nearby.
WATERING SCHEDULE
Open the faucet for 45 minutes to 1 hour every 2 to 3 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.
