Step 2- Using wire splice connectors, attach either
wire from each valve solenoid to the white cable
wire. This wire is designated as the valve
“Common Wire.” Connect the remaining wire
from the solenoid to one of the color-coded wires.
The Toro 1" in-line electric valves are designed for use
in an automatic sprinkler system controlled by
a 24 V a.c. sprinkler system timer. The valves feature
manual bleed controls which enable the valve to be
operated without the use of the timer. The 53706
valve is designed for slip-fit pipe connections and
model 53708 features female-threaded inlet and
outlet. These valves are generally installed below
grade, grouped with other valves in a manifold
arrangement and housed in a protective valve box.

Important: All wire splices must be insulated
with grease caps or similar waterproofing devices.
Step 3-At the timer, connect the control wires to
the numbered terminals in the desired operating
sequence and the valve common wire to the com-
mon terminal.

Important: These valves do not provide backflow
protection. A backflow prevention device installed between the
1" in-line valve(s) and the water source point of connection is
Step 4-Using the timer’s manual control feature,
test the operation of each valve.

required in most areas to prevent back-siphoning of contaminants through the sprin-
kler system into the potable water supply. The Toro 1" Pressure Vacuum Breaker
(PVB), model number 53300, is specifically designed for this purpose. Before connect-
ing your irrigation system to the potable water supply, consult with your local water
utility department for information regarding backflow prevention requirements.
Where local water pressure exceeds 70 psi, a pressure regulator should be used. (See
Uniform Plumbing Code, Sec. 1007 [b].) It is advisable to use a regulator with any
automatic valve to assure long life as well as uniform and controllable operation.
