The King Drains Valve Protector (Part #21155) is a compact drain insert designed for commercial and industrial irrigation systems. It fits standard 1" MIPT/1" MPT connections and protects drains with a pressure-sensitive release mechanism that reduces standing water while preventing blockages.

  • Pressure-sensitive valve: Enables controlled, slow release of water to reduce pooling and erosion.
  • Self-cleaning dirt-arrestor screen: Captures debris and minimizes clogging to maintain reliable drainage.
  • Patented backflow check: Prevents contaminated water from re-entering the irrigation system.
  • Broad dispensing pad: Shields the outlet from soil and root intrusion for long-term performance.
  • Ergonomic installation grip: Textured, slip-resistant body eases insertion and removal in tight spaces.
  • Available packaging: Sold individually and as a case (5 per bag) to suit contractors and maintenance teams.

Part number 21155 is an easy-to-install solution for keeping irrigation drains clear and sanitary. For routine maintenance, inspect the screen periodically and remove debris as needed to ensure continuous operation.
