pressure from reaching pilot valve
(and solenoid valves if applicable).
1. Manually rotate the pilot (in the

closed. (Refer to the valve flow di-
agrams on page 66). Remove
the control tubing from the valve
port cover and check for water
from the tube.

(Home) position.
If water flows out of the control tubing,
check the fitting in the valve port cover
for an obstruction.If water does not
flow out of the control tubing, check
the control tubing and fitting in the pi-
lot body for an obstruction.
