10. Precision Level: Ensures perfect installation.
11. Brass Pin: Enhancing durability and performance.
12. Outlet: Designed for seamless water flow and effective drainage.

Functioning

The valve allows unidirectional water flow. Outgoing water from the household pushes the plate open, directing it into the public sewer system. In case of backflow, the plate remains in a closed position, preventing flooding.

• Plate Locking: The locking knob must be set to "OPEN" for normal operation.
• Manual Closure: The valve features a locking knob to hold the plate in the closed position, recommended for extended absences from home. Rotate the knob clockwise to set it to "CLOSED."
• Maintenance: Requires minimal upkeep, but a periodic inspection every 12 months is advisable. High technical standards, premium materials, and simple components ensure product longevity.

Benefits

• Easy Installation and Inspection: Intuitive design for simplified setup and maintenance.
• Minimal Maintenance: Removable plate for easy periodic cleaning.
• Optimized Design: Smooth walls and rounded corners to prevent debris buildup.
• Durable Seals: Enhanced stability and resistance to wear.
• Comprehensive Protection: Prevents flooding, rodent intrusion, and foul odors.
