Beyond Screw-in Bulbs Quality LED retrofits match beam angles and CRI expectations. Cheap discs often create hot spots and odd color fringes. Transformer Compatibility Magnetic transformers may need minimum load; electronic units often handle low LED wattage better. Color and Glare Warmer 2700–3000K is typical for residential paths; cooler temps suit modern architecture when glare […]
Load Math That Survives Summer Add fixture wattages (or VA) and multiply by manufacturer minimum headroom—often 20–25%. LED loads are lower but inrush still matters on some transformers. Voltage Drop Planning Long homeruns need thicker gauge or multi-tap transformers. Sketch zones so no leg runs near max length for its gauge. Tap Strategy Distribute load […]
California, Arizona, Nevada, and Colorado all have mandatory smart irrigation requirements in 2026. This contractor guide covers what to specify on every Western US job to meet water restriction rules and qualify for utility rebates.
What a Master Valve Does A master valve sits upstream of zone valves and closes whenever no station runs. It can stop catastrophic leaks downstream if the controller commands it closed. When to Add One Sloped sites, high static pressure, and systems with history of stuck zone valves benefit most. Pair with flow sensing for […]
Why a Relay Exists Controllers output low-voltage signals; pumps need high-voltage contactors. A pump start relay bridges that gap safely. Wiring Discipline Follow the pump and controller manuals exactly. Label commons, MV, and pump terminals to avoid cross-talk during service. Safety Hardware Lockable disconnects, proper grounding, and strain relief on flex protect technicians and homeowners. […]
Complete contractor installation guide for the Rachio 1″ wired flow meter (1004-EX) and wireless flow meter (WM-1000). Learn setup, leak alert configuration, and how to generate water usage reports for compliance audits.
Protecting Potable Water Irrigation systems can draw fertilizer or debris back into drinking water during pressure reversals. Backflow preventers stop that pathway. Common Residential Types Pressure vacuum breakers (PVB) are common where code allows; reduced pressure (RPZ) assemblies add protection where hazards are higher. Testing and Tags Most jurisdictions require annual certification. Keep tags on […]
Where PVC Shines Schedule 40 PVC is rigid, easy to solvent weld, and ideal for straight mainlines with predictable trenching. Where Poly Wins Polyethylene handles curves, rocky soils, and quick repairs with barbed fittings and clamps—common on laterals to valves. Depth and Code Follow local depth tables and separation from other utilities. Mark depth on […]
Start at the Controller Confirm the station output energizes when commanded. Intermittent faults may be wiring nuts, cut common wires, or corroded connectors. Voltage and Ohms Measure AC voltage at the solenoid leads during operation. Compare coil resistance to manufacturer ranges—shorts and opens are common after lightning seasons. Mechanical Issues Debris under the diaphragm or […]
Teach the Controller Your Landscape Accurate plant type, sun exposure, and sprinkler head selections change ET math. Garbage inputs produce garbage run times—even with good weather data. Weather Sources Choose a reliable station near the property. Rural sites may need a personal weather device for wind and rainfall. Flow and Overrides If you add flow […]
