Big Irrigation Tricks

Plan for Service Unions or snap fittings save hours when a valve body fails. Leave hand space—even if it costs a bigger box. Label Everything Zone numbers, flow direction, and water source—future you will thank you. Drainage Pea gravel and weep holes prevent soup boxes that corrode solenoids. Winterization Loops Orient ports so blowouts actually […]

Set the Left Stop First Follow the brand’s left-edge procedure before dialing the right stop—backwards order causes confusion. Match Nozzle to Arc Nozzle charts assume specific arcs. Changing arc without re-nozzling skews precipitation. Check Collars and Screens Debris holds arcs short and causes side spray. Walk the Pattern at Night Darkness reveals mis-throws toward windows […]

Grade Changes Over Time Mulch and turf buildup bury heads. Top-of-head should sit level with soil per manufacturer—not sunken or sticking up into mower paths. Level the Body Tilted heads throw uneven arcs and waste water on pavement. Nozzle Hygiene Clean screens while adjusting and replace cracked nozzles immediately. Final Audit Run the zone and […]

Know the Field Layout Locate tanks, distribution boxes, and leach lines before trenching. As-builts are often wrong—verify. Spray Drift Avoid spraying over septic mounds; wind carries moisture and salts onto components. Root Management Thirsty plants near lines invite roots. Choose appropriate species and irrigation methods. Code and Health Follow local setbacks—failures are expensive and hazardous. […]

Why White Crust Appears Evaporation concentrates salts at the soil surface. Poor drainage accelerates damage even with “enough” water. Testing Annual lab panels for EC, SAR, and key ions guide amendments—not guesswork. Emitter Fouling Hard water and biological slime clog pathways. Pair chemistry with filtration. Turfgrass Tolerance Some varieties handle salinity better—coordinate with seed selection […]

Match Orifice Size Finer emitters need finer filtration. Oversizing screen holes courts clogs downstream. Disc vs Screen Disc filters handle organic loads well; screens are simple and cheap for cleaner sources. Flush Points Install flush valves and teach crews a routine—partial clogs show up as edge dry-out first. Water Source Clues Well water with iron […]

Hydraulics at Scale Loops and variable-frequency drives balance pressure across huge systems. Failures cascade fast—monitor flow relentlessly. Central Control Superintendents need dashboards, not just timers. Integrate weather, soil sensors, and pump health. Sustainability Story Document every gallon saved—communities scrutinize water use on courses. Parts Strategy Stock critical rotors and decoders during peak season—lead times spike. […]

Why Two-Wire Wins at Scale Pulling hundreds of home-run conductors is expensive. A two-wire path carries power and data to addressed decoders at each valve. Diagnostics Modern controllers report shorts, opens, and decoder faults—plan training so crews trust the data. Lightning and Surge Follow manufacturer grounding and surge plans—two-wire paths are not magic shields. Expansion […]

Read the Ordinance Restrictions vary by street, water district, and drought stage. Capture the exact allowed days and hours in writing for HOAs. Controller Tools Use non-watering days, program copies, and seasonal adjust to stay compliant without rebuilding schedules weekly. Exemptions New plantings sometimes qualify for temporary variances—document start and end dates. Enforcement Reality Fines […]

What ET Actually Means Evapotranspiration combines soil evaporation and plant transpiration. Controllers use reference ET then adjust for plant type and density. Field Verification Walk zones monthly. If turf looks wilted while ET says decrease, your crop coefficients may be wrong or heads are clogged. Uniformity First Poor DU wastes ET math. Audit catch cans […]
