Troubleshooting
Symptom Solution
Valve
Won’t Turn
On when
Solenoid is
Turned
Make sure ow control is open (select
models)
Check that main water supply is on
Make sure piping is connected properly and
not blocked
Valve Won’t
Turn On at
the Timer
Verify timer settings are correct
Check and repair wiring and connections as
needed
Check and replace valve solenoid as needed
Verify timer power output
Valve Won’t
Shut-o
Verify timer settings are correct
Hand tighten solenoid and bleed screw if
needed
Valve Won’t
Turn On at
the Valve
Incorrect timer settings
Check wiring
Check solenoid
Timer not supplying power to the valve
Make sure the Flow Control stem is not
turned all the way closed
Leaks at
sprinkler
heads
Clear debris by opening the bleed screw
and ushing 1 minute
Remove and clean the diaphragm. Replace if
needed.
Leaks
around the
valve
Check pipe ttings connection and glue,
repair or replace as needed
Hand tighten solenoid and bleed screw if
needed
If vacuum breaker is leaking (anti-siphon
models) remove cap, gasket, and internal
piston gasket to clean and reassemble
Turn o main water supply, relieve pressure
on the valve by opening the bleed screw
and tighten the jar top bonnet
NOTE: During winter, shutdown and drain the
