CONNECTING TO AN EXISTING
UNDERGROUND SPRINKLER SYSTEM
Connecting to an existing underground sprinkler system (or Retrofit) is a sim-
ple way to supply water to your Drip-Irrigation system. Retrofits are commonly
used to conserve water by replacing inefficient shrub sprinklers and bubblers.
Retrofit Drip-Irrigation
systems consist mainly of
1
Manifold—Attaches to a ½" riser
and consists of 1 to 8 outlets.
2
¼" Distribution/Supply Line
3
Low-Volume Sprinkler, Dripper,
or Soaker Tube
MANIFOLDS
The main function of a Manifold is to distribute water through ¼" outlets.
There are 4 types of Manifolds
1
Adjustable Flow Manifolds—Ideal when water system pressures
exceeds 40 PSI and where flow control is desired.
2
Full Flow Manifolds—Ideal for replacing inefficient shrub heads and
bubblers.
3
Shrub Adapter—Ideal for micro-sprinklers.
4
Riser Adapter Manifolds—Permits Drip-Irrigation without
eliminating a sprinkler head.

INSTALLATION FOR ADJUSTABLE
FLOW, FULLFLOW, AND RISER
ADAPTER MANIFOLDS
1
Remove sprinkler head from a ½"
Riser and attach the manifold. (For
Riser Adapter Manifold, reattach
sprinkler head).
2
Remove Cap(s) from the ¼" Barb(s)
and insert ¼" Distribution/Supply Line.
3
Attach a Low-Volume Sprinkler or
Drip-Irrigation Dripper to the end of
the Distribution/Supply Line.
4
To avoid high water pressure
failure, install a ¼" High Pressure
Clamp on all tube connections.
5
Position Drip-Irrigation Dripper
next to plant.
6
If applicable, adjust flow-control
knob for desired flow rate.
