Getting a residential irrigation system ready for spring involves more than simply turning on the water. A careful start-up can reveal winter damage, leaks and coverage problems before peak watering season.
1. Inspect Before Pressurizing
Check exposed piping, backflow components, sprinkler heads, valve boxes, wiring and the controller for obvious damage or deterioration.
2. Pressurize Slowly
Close manual drains, then open the irrigation supply gradually. Listen and look for leaks as the system fills.
3. Test Every Zone
Look for dry areas, overspray, damaged or clogged heads, leaks and pressure problems. Check that valves open and close correctly.
4. Program the Controller
Set schedules to match current local watering rules and actual seasonal conditions. Use appropriate run times and consider cycle-and-soak programming where runoff is a problem.
5. Adjust for the Landscape
Lawns, trees, shrubs and flower beds do not necessarily need the same watering method. Landscape changes may justify nozzle changes, zone adjustments or conversion of suitable areas to drip irrigation.
When to Call a Professional
Persistent low pressure, electrical issues, underground leaks, valve problems and recurring coverage issues usually benefit from professional diagnosis.
