Troubleshooting and Maintenance of drip irrigation system

 

Problem Potential Cause Solution
Electric valve does not operate properly 1) Wrong valve size, flow too low
2) Valve diaphragm orifice is plugged
3) Solenoid faulty
1) Replace with correct size
2) Clean or replace diaphragm
3) Check wiring, or replace solenoid
Battery operated controller does not operate properly Check the battery, make sure the controller contact touches the battery Replace battery or with your finger lift the battery clip upward
Pressure regulator leaking Dirt inside the pressure regulator Remove from line, remove the washer and wash with water or replace
Dripper or micro sprinkler has uneven or no flow Line broken, filter clogged, dripper clogged or faulty, pressure too high or too low Check drip line, clean or replace screen filter, replace or clean dripper or nozzle of micro sprinkler, check pressure regulator.
Dripper or micro sprinkler has uneven or no flow at the end of the drip line Too many drippers on the drip line Make sure that you did not exceed the recommended maximum flow of 200 GPH
Fittings separating from drip tubing or drip line 1) Fittings improperly installed
 
2) Wrong fittings with use with your drip tubing
1) Tubing is not far enough inside the compression fitting
2) Make sure you used the correct size fitting
Dripper or micro sprinkler popping out of drip tubing 1) Pressure regulator is defective, drippers or micro sprinklers are installed improperly; faulty or worn punch
 
2) Pressure is to high
1) Replace pressure regulator, check or replace drippers or micro sprinkler, plug hole with goof plug, replace or clean punch
2) Install pressure regulator or replace
Clogged drippers, what steps do you try The use of a proper filter should avoid clogging problems, but 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.
Clogged drippers at the end of the line   If many drippers are clogged, chances are there is a break in the line. Check your 1/2" poly tube
No water flow from drippers or micro sprinklers The use of a proper filter should avoid clogging problems, but if you do find clogged drippers, here is a step to try Clean screen in faucet adapter or open the filter and clean the screen by washing with water
Drippers or micro sprinklers have calcium deposits (white color buildup) Hard water You can remove dripper or micro sprinkler from the line and soak for one hour in a chlorine solution
Plants appear stressed 1) Drippers near the plants are plugged
2) Break in the drip tubing
 
3) Run time is inadequate for the plants
1) Replace drippers, check filter and clean
2) Repair break using coupling
3) Adjust the controller program and add more time

Maintenance

  • Inspect drippers, micro sprinklers and micro tubing periodically to insure that no drippers are clogged, or that any of the micro tubing is out of place.
  • Filter screens should be flushed and cleaned at least once a month depending on water quality. Checking the filter one week after installation should give you an idea on how often to schedule cleaning.
  • Drip tubing should also be flushed periodically; again, water quality will determine the frequency of flushing.
  • During freezing weather, we recommend draining your poly tube or rolling it up and storing it.
  • During freezing weather, we recommend removing the battery operated controller for the season.
  • Remove end caps or open hose ends to flush the line once a year.
  • As your landscape matures, you may need to add, change or remove drippers or micro sprinklers.
