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 […]
HOAs face escalating water fines in 2026. Irrigation contractors who combine Hunter Hydrawise or Rachio Pro Series with flow meter monitoring are winning HOA management contracts. Here is the business model that works.
Why Slopes Run Off Water travels downhill faster than it infiltrates. Long single cycles on clay soils guarantee puddling at the toe. Cycle-and-Soak Break runtime into shorter pulses with soak gaps so moisture redistributes vertically. Head Placement Follow contour lines where possible and avoid aiming heads directly downslope across pavement. Plant and Mulch Strategy Deep-rooted […]
What You Are Hearing Water hammer is a pressure spike when moving water stops suddenly. Plastic and copper mains both transmit the shock. Common Irrigation Triggers Fast-closing solenoids, long pipe runs, and high velocity combine to amplify spikes. Mitigations Slow valve opening when possible, add air relief where trapped air exists, and consider surge arrestors […]
Drip irrigation is exempt from most North American day-of-week watering restrictions. This contractor guide covers why drip conversion is the highest-ROI upgrade in 2026 and how to spec, sell, and install it.
Define the Goal Accent trunks, reveal branching structure, or graze bark texture. Each goal picks a different beam and mounting height. Beam Spread and Distance Narrow beams punch canopy holes; wide floods soften silhouettes. Combine layers for large specimens. Glare Control Shrouds and glare guards keep light out of bedroom windows and driver sight lines. […]
