TABLE 10-2: TROUBLE SHOOTING
Problem Potential Cause/Solution
Valve does not
operate properly.
Wrong valve selected, flow too low. Replace with correct size Xerigation
Control Zone.
Valve diaphragm is contaminated. Clean or replace diaphragm.
Solenoid faulty or wire severed. Check wiring. Repair or replace solenoid.
Emission device
has uneven or no
flow.
Line severed upstream of emission device. Check for breaks and repair.
Filter clogged or inadequate. Check, clean, or replace filter.
Emission device clogged or faulty. Replace emission device.
Pressure too high or too low. Check pressure regulator to assure flow
compatibility.
Too many emission devices on one line or line sized improperly for flow.
Check and correct.
Emission device
flow is too high or
too low.
Check to make sure emission device is not installed backwards.
Remember, the pointed end of a Xeri-Bug or PC Module is the inlet.
Poly drip tubing
comes out of
fittings when line
is pressurized.
Fitting improperly installed, or wrong size fitting has been used. Check
and replace.
Pressure too high because regulator is not matched to flow.
Emission devices
come loose from
tubing.
Emission device installed improperly. Emitter punch tool creating holes
that are too big resulting in emitters that are loose.
Pressure too high. Check pressure regulator to assure flow compatibility
and whether installation is in correct direction.
Faulty or worn hole punch. Replace bad section of tubing and use
Xeri-Tool to insert XB emitters with self-piercing barbs so that maximum
retention strength is obtained.
Plants appear
stressed.
Tubing stake was not used and point of emission has been moved away
from plant root zone due to maintenance.
Emission device at plant is clogged. Clean or replace emission device.
Filter is clogged and preventing flow. Clean or replace filter.
Check for and repair breaks in 1/4” or 1/2” line upstream of the emitter.
Run time inadequate for plant and/or time of year. Recalculate water
requirement and schedule.
Controller faulty or off. Check controller and reset, repair, or replace.
