Why K-Rain

  • Signature indexing valves simplify multi-zone systems with one supply line
  • Efficient nozzles & rugged rotors for even, water-smart coverage
  • Retrofit-friendly controls that work with standard 24-VAC valves

Upgrade ideas: Add a smart controller for weather-aware schedules, swap standard sprays to pressure-regulated bodies with rotary nozzles, or use K-Rain indexing valves on pump-fed systems to run multiple zones from one line.
