Troubleshooting
Valve will not open.
1. Ensure main water supply is on. Ensure
upstream valves are open. Ensure flow
control stem is not closed.
2. If valve only opens with manual bleed,
ensure controller is programmed to acti-
vate the proper zone valve. Test controller
power output and service if necessary. Test
solenoid power input.
a) If controller and solenoid power are
detected, insert a thin flat screwdriver
into the slotted areas of the solenoid
bottom and brown solenoid retainer.
Gently pry to disengage retainer.
Remove plunger assembly and clean
debris.
Replace plunger ensuring black surface
faces outward. Snap retainer into place
ensuring the larger hole faces outward.
Persistent problem may be an obstruc-
tion lodged in main pipe.
b) If power is detected at the control-
ler and not the solenoid, inspect and
repair damaged lead wires.
Valve will not close.
1. Ensure controller is not operating the valve
automatically. Ensure manual internal
bleed is off by clockwise tightening the
solenoid adapter. Ensure manual external
bleed is off by clockwise tightening the
valve bleed screw.
2. Turn off water supply and swap solenoid
from an operational valve; replace solenoid
if necessary.
3. Turn off water supply and verify that the
solenoid adapter o-ring is not damaged;
replace if necessary. Check for debris in
solenoid bowl preventing plunger from
creating a positive seal.
4. Check overall system water-pressure
requirements and ensure that multiple
zone valves are not operating simultane-
ously. Disallowing one zone valve to close
before another opens can reduce the
