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 […]
Why One Threshold Does Not Fit All Turf roots are shallow; shrubs pull from deeper layers. A single global threshold will overwater one and underwater another. Calibration Steps Baseline readings after irrigation and after dry-down. Map those to controller setpoints instead of guessing vendor defaults. Sensor Placement Install in representative soil, not in pure sand […]
Wi-Fi doesn’t reach every irrigation site. The Rachio Cellular Connect module delivers full Pro Series smart controller features via LTE at any location with cellular coverage — vacation homes, rural properties, and construction sites.
Location Matters Mount sensors with open sky exposure but away from walls that shed water unpredictably. Keep them clear of sprinkler spray and gutter splash. Height Guidelines Follow manufacturer height and tilt guidance—many units need level mounting to drain properly after storms. Wired vs Wireless Wired sensors avoid battery issues but require clean routing. Wireless […]
Why Wire Size Matters Solenoids need adequate voltage at the end of the run. Undersized wire causes weak pulls and ghost operations. Home Run vs Daisy Chain Home-run each valve when possible for cleaner troubleshooting. Daisy chains save copper but complicate fault isolation. Splices That Survive Use waterproof connectors rated for direct burial and tug-test […]
