Troubleshooting

<< previous   show t.o.c.   next >>

AC valve does not operate properly:
  • WRONG VALVE SIZE, FLOW TOO LOW: replace with correct size valve
  • DIAPHRAGM ORIFICE IS PLUGGED: clean or replace diaphragm
  • SOLENOID FAULTY: check wiring or replace solenoid
Battery operated controller does not operate properly:
  • CHECK THE BATTERY: make sure the 9-volt controller battery is good, replace battery
Battery operated controller does not close:
  • PUPPET IS MISSING, "O" ring #2 is missing, lever is in the open position visit the replacment parts page
  • DIAPHRAGM is torn, or worn out, visit the replacment parts page
  • SOLENOID PLUNGER is missing or upside down VALVE is installed backwards
Pressure regulator leaking:
  • DIRT INSIDE THE PRESSURE REGULATOR: remove from line, remove the washer and clean
  • REGULATOR IS INSTALLED ON MAINLINE. Move to downstream side of control valve.
Drippers or micro sprinklers have uneven or no flow:
  • LINE BROKEN, FILTER CLOGGED, DRIPPER CLOGGED OR FAULTY, OR PRESSURE TOO LOW: check mainline for leaks, clean or replace screen filter, replace or clean dripper or nozzle of micro sprinkler, check pressure regulator
Drippers or micro sprinklers have uneven or no flow at the end of the line:
  • TOO MANY DRIPPERS ON THE LINE: make sure that you did not exceed the total maximum recommended flow rate (220 GPH)
Backflow preventer leaks or vibrates:
  • Make sure it is installed downstream of timer and not on a mainline
Fittings separating from 1/2" poly tubing:
  • FITTINGS IMPROPERLY INSTALLED: tubing is not far enough inside the compression fitting
  • WRONG FITTINGS USED WITH DIG POLY TUBING WITH .700 OD: cut the 1/2" poly tubing and make sure to use .700 OD fitting with color code black insert
Drippers or micro sprinklers popping out of poly tubing:
  • PRESSURE REGULATOR IS DEFECTIVE: replace or clean pressure regulator
  • PRESSURE IS TOO HIGH: install pressure regulator or replace
  • DRIPPERS OR MICRO SPRINKLERS ARE INSTALLED IMPROPERLY: faulty or worn punch, check or replace drippers or micro sprinklers, plug hole with #56 goof plug, replace or clean punch
Clogged drippers:
  • THE USE OF A PROPER FILTER SHOULD AVOID CLOGGING PROBLEMS. If you do find clogged drippers, here is a step to try: while the water is on, hold your finger over the dripper outlet for a few seconds. This "back flushing" will usually work
Many drippers are not working:
  • IF MANY DRIPPERS ARE CLOGGED: chances are there is a break in the line and dirt is penetrating the system, check 1/2" poly tubing and using #17 fittings to patch as needed
  • THE USE OF A PROPER FILTER SHOULD AVOID CLOGGING PROBLEMS: clean the screen in the swivel adapter or open the filter and clean the screen by washing with water END OF LINE IS OPEN
No water flow from micro sprinklers model 8855-xx:
  • PROBLEM OCCURS IN A MICRO SPRINKLER MODEL 8855, 8855-1 ON A SPIKE OR 8855-5 ON A SPIKE: remove nozzle from "C" shaped head and rinse nozzle thoroughly under water
Threaded fittings are leaking:
  • CHECK THREAD TYPE (hose or pipe) and do not combine hose thread with pipe thread fittings
Drippers or micro sprinklers have calcium deposits (white color buildup):
  • HARD WATER: remove the drippers or micro sprinklers from the line and soak for one hour in a weak chlorine solution
Plants appear stressed:
  • DRIPPERS NEAR THE PLANTS ARE PLUGGED: replace drippers, check filter and clean
  • BREAK IN THE POLY TUBING: repair break using #17 connector or #56 goof plug
  • RUN TIME IS INADEQUATE FOR PLANTS: add more time to the controller station
