Building a Year-Round Sprinkler Maintenance Plan

A season-by-season maintenance calendar that keeps an irrigation system efficient and prevents the repairs that cost the most.

Maintenance is cheaper than repair

Almost every expensive irrigation failure we attend was preventable: a freeze-damaged backflow device, a valve that ran all month, a zone quietly watering a fence for two summers. A simple calendar prevents all three.

Spring (mid-April to May)

  • Controlled startup and slow pressurization
  • Full zone-by-zone inspection and head adjustment
  • Backflow device inspection
  • Controller reprogrammed for spring rainfall
  • Rain sensor tested

Early summer (June)

  • Catch-cup audit on problem zones
  • Nozzle changes where coverage is uneven
  • Run times increased as temperatures rise

Midsummer (July-August)

  • Monthly walkthrough while a cycle runs
  • Watch the water bill for unexplained jumps, the earliest sign of a stuck valve or underground leak
  • Trim vegetation blocking heads

Fall (September-October)

  • Reduce run times as evapotranspiration drops
  • Repair anything you have been tolerating; it is far cheaper now than in the spring rush
  • Book winterization before the first hard frost

Late fall (October-November)

  • Compressed-air blowout, zone by zone
  • Backflow device isolated and drained
  • Controller set to off or rain mode
  • Written condition report filed for spring

Let us track it for you
