INSTRUCTIONS
Step 1:
Begin by unrolling the 100 foot coil of pipe,
making sure not to kink the pipe in the
process.
Step 2:
Let the pipe rest in the sun for 15-30
minutes, which will make it easier to form
into place.
Step 3:
Starting from one end, cut the pipe into four
20-foot sections and two 10-foot sections.
You should have the exact amount to do
this. This allows for 20-foot spacing of
sprinkler heads, which will give proper head
to head coverage.
Step 4:
Lay out the pipe in the approximate location
of each section. Don’t worry if the pipe still
stays coiled, it will straighten as fittings are
attached.
Step 5:
Lay out the fittings next to their general
connection points.
Step 6:
In this step, attach the hose swivel adaptor
to the eco-lock pipe adaptor. Then connect
one of the 24-inch sections of pipe to the
transition adaptor by twisting while pressing,
and then connecting the timer. Finally,
attach on the other end a ¾-inch tee,
followed by one of the 10-foot lengths of
pipe.
Step 7:
Cut the other 24-inch section of pipe into
four, 6-inch sections, then attach an elbow
to the other end of the 10-foot section,
followed by a 6-inch piece.
Step 8:
Moving down the line, attach a threaded
tee, followed by the first 20-foot section.
Another threaded tee, and a second 20-foot
section, then a final threaded tee, 6-inch
section and threaded elbow.

Step 9:
in this step we attach sprinklers by first
attaching the ½-inch riser to the bottom of
the sprinkler and slipping the retaining loop
over the sprinkler before threading on to the
fitting. Position the sprinkler and hold up
with staked loop.
Next we thread on the auto-drain valve.
Repeat this for the remaining fittings,
sprinklers and drain valve on the other side.
Step 10:
We’re now ready to test the system. Run a
manual program on the timer, being aware it
may take up to 30 seconds for the lines to
pressurize. Assure all sprinklers are
spraying and that there are no leaks.
Step 11:
Next, adjust the sprinklers to their desired
patterns. For more information on how to
adjust your sprinklers, please see the video
linked above.
Step 12:
Starting in the corners, dig a trench about
four inches wide and 4-6 inches deep,
pulling up the grass as you go. Place the
pipe into the trench, burying it as you go.
Pay attention that the sprinklers are nearly
flush to the ground.
Remove any excess soil. Your system
should now be ready to go. The grass
should heal within a matter of weeks.
