Installation Guide

Before You Start
Check local codes to ensure that you have secured all
necessary permits. In addition, have your local
utilities mark all the buried lines and pipes before you
start digging. In many areas, simply dialing 811 will
c
onnect you with one resource that will arrange to
have all your utilities marked. Otherwise, contact your local utility
provider(s) directly.

STEP 1: Connect the Water Source
MARK YOUR SPRINKLERS, RISERS, VALVES & TRENCHES
Use marking flags to indicate sprinkler locations according to
your design. Also, mark the location of your drip system risers, if
applicable. Even if you plan to install the drip system at a later
date, you can install your drip risers with the rest of your system
now. Use line-marking spray paint to mark where you’ll trench
for pipes and wiring. Check your design to make sure you mark
the lines accurately. You will be digging your trenches along
these lines.
TAP INTO THE MAIN LINE
By cutting into your service line and slipping on a compression
tee, you can connect your irrigation system to the water supply
without soldering. Depending upon the location of your water
meter, the steps that follow will guide you through tapping into
the main line.
Additionally, we recommend installing a shut-off valve between
the zone valves and the service line. This will allow you to easily
turn off the water to your irrigation system if you need to make
repairs or replace parts. Check local codes for the type of
shut-off valve recommended.
A. If the meter is in your yard:
1. Shut off your water supply at the meter.
2. Dig to expose the service line.
3. Tie into the service line, between the water meter and the house.
4
. Remove a section of pipe, leaving a gap large enough to slide
on the compression tee.
5. Slip the tee over each end of the pipe.
6. Tighten the compression nuts. The rubber gasket will
compress against the pipe, creating a seal to prevent leakage.
7. Install a short nipple, using PTFE tape on all threaded
connections to the tee.
8. Attach a shut-off valve, in a small enclosure, to this section of
pipe. The shut-off valve allows you to turn off the system by
hand, if necessary. This is your tap water supply so try to keep
the connection as clean as possible.
B. If the meter is in your basement:
1. Shut-off your water supply at the meter.
2. Install an appropriate tee into the service line for the
irrigation connection.
3. Drill a hole through the sill above the foundation, or chisel a
hole in the basement wall for the irrigation line to run
through. Make the hole no larger than necessary for the pipe
specified on your design.
4. Install the connection fittings, as shown below. A ball valve is
a good choice for the irrigation shut-off. For the drain valve,
use a gate-type valve. The drain valve should be as low as
possible to allow complete system drainage.
5. Feed your irrigation system pipe out through the basement
wall, and run it to the backflow preventer location.
6. Seal the hole in the sill or foundation with caulking compound.
Cold Climates: If you live in an area where freezing occurs, it is
best to contact a professional to winterize your system in the fall.
However, to make attaching the air line for blowing out your
system easier, add a tee in the main supply line (S x S x T)
between the Pressure Vacuum Breaker (PVB) and valve manifold.
Screw a cap onto the extra leg.
