Q: How often should an irrigation system be serviced in South Africa?
Irrigation systems should be professionally serviced annually under SANS 10252. Service includes solenoid valve function test, zone flow rate measurement, backflow prevention valve inspection, controller programme verification, and sprinkler head condition check. An unserviced system can waste up to 40% of water through undetected leaks, failed solenoids, and blocked heads — particularly problematic under Cape Town and Gauteng water restrictions.
What the annual irrigation service covers
✓Solenoid valve function test — each zone solenoid activated and tested; failed solenoids either stick open (waterlogging) or closed (dead zone)
✓Zone flow rate measurement — flow measured per zone; significant deviation indicates a leak or blockage
✓Backflow prevention valve inspection — required under SANS 10252; prevents irrigation water contaminating municipal supply
✓Controller programme verification — schedule and rain sensor verified; power interruptions frequently corrupt controller settings
✓Sprinkler head and nozzle check — heads raised, rotors tested, blocked nozzles cleared or replaced
✓Pipe and fitting integrity — visible pipework inspected for leaks, root damage, and UV degradation

Frequently asked questions
Does load shedding affect irrigation controllers?+
Yes. Power interruptions frequently reset irrigation controller programmes to factory defaults — meaning the system doesn't run or runs at incorrect times. Annual service verifies and restores the correct schedule.
Is backflow prevention required by law?+
Under SANS 10252 and most municipality by-laws, a backflow prevention valve is required on any irrigation system connected to the municipal supply. Absence can result in the municipality cutting water supply to the property.
What if my system has a borehole supply?+
Borehole-fed irrigation is serviced under the same bundle. Borehole pump condition is noted and referred to the borehole pump service if issues are identified.
