STEP 1
Test Your Pressure
Attach the pressure gauge to the desired hose faucet, turn
water on to find out how much pressure is available.
If pressure exceeds 80 psi it is recommended
to use a pressure reducer.
If pressure is below 35 psi, please note that
this system may not work as designed.
STEP 2
Determining Sprinkler Head Spacing
Your available pressure will determine how far your
sprinkler heads will spray water. Use this chart to help
you determine how far apart to space your heads.
Distances are approximate and based on the
Orbit recommended, U-shaped, design.
Performance will vary based on your design, and whether
or not you choose to use all of the sprinkler heads in the kit.
The spacing is based on the .75 nozzle provided with the kit.
Distance will vary if the nozzle is changed.
STEP 3
Prepare the Blu-Lock Pipe
· Unroll the 125' coil of pipe, making sure
not to kink the pipe in the process.
· Let the pipe rest in the sun for approximately one
hour (depending on how warm it is outside), which
will make the pipe easier to put into place.
While you are waiting for the pipe, you can
move on to the next few steps.
STEP 4
Design Your System
For optimal coverage and health of your plants, locate
each sprinkler so that the spray distance reaches
adjacent sprinklers. Ideally the sprinkler heads’ spray
pattern will spray over each head a short distance.
· Orbit recommends the U-shaped design shown
in this manual, but this design can be adapted
to the unique shape of your landscape.
· To ensure proper pressure and spray coverage of
your lawn, do not put any more than three sprinkler heads on any length of pipe.
· If you have the 2-zone kit, adapt this design for your second zone. It is okay to have
extra parts left over when you are done; we added parts for varying layouts.
STEP 5
Connect the Timer
Connect the timer to the desired faucet and then connect
the Hose to ½" Blu-Lock adapter to the timer.
STEP 6
Cut the Pipe
Cut the pipe where tees, elbows, and couplings will be
located. Mark the Blu-Lock pipe one inch from the end before
installing the fittings. This mark will help you know how far
to push the fittings on to the Blu-Lock pipe. Don’t worry if the
pipe stays coiled, it will straighten out as fittings are attached.
STEP 7
Connect the Fittings
Connect the Blu-Lock pipe to the Hose to Blu-Lock adapter,
tees, elbows, and couplings where you made your cuts.
Make sure to push the pipe all the way into each fitting
using the marking you made in Step 6. Attach sprinkler
heads and auto-drains to the appropriate fittings.
Auto-drains allow water to purge the pipes, reducing possible
damage to your system. This does not take the place of
winterizing your irrigation system. Be sure to properly
winterize if you live in an area with freezing temperatures.
STEP 8
Test Your System
Above ground, place your pipes, sprinkler heads, and drains
in the desired location. Stake or secure your sprinkler heads
to the ground so they will not move when you turn your
water on to perform this test. Turn your water on slowly.
Look for leaks. Blu-Lock fittings are designed to be
removed in case adjustments are needed. First make
sure that your water is off, then simply pull back on
the blue tabs located at the end of the fitting, push
the pipe in, twist the pipe, then pull the pipe out.
Leave the water on. If water does not reach from
sprinkler head to sprinkler head, see Step 9.
