Zurn Z100F Roof Drain

What Is the Zurn Z100F?

The Zurn Z100F is a high-capacity roof drain designed for flat and low-slope roofing applications. It features an innovative hydraulic design that maximizes flow rates while maintaining a watertight seal with the roofing membrane. The included dome strainer prevents debris from entering the system, ensuring reliable operation during even the heaviest storms.

Key Features & Benefits

• Superior Flow Performance: Engineered to remove stormwater quickly, minimizing ponding and structural stress.
• Durable Dome Strainer: Keeps debris out of the system while maintaining water intake capacity.
• Watertight Membrane Connection: Flashing clamp secures the roofing membrane for long-lasting leak protection.
• Engineered Reliability: Hydraulic efficiency designed for demanding commercial use.
• Corrosion-Resistant Materials: Built to withstand long-term exposure and maintain durability.

• Inspect and clean dome strainers regularly to maintain drainage capacity.
• Perform water testing after installation to confirm system performance.

Zurn Z100F Installation

Case Study: University Campus Upgrade

Challenge: A university with several flat-roof buildings faced recurring ponding and membrane wear during storm events. The existing drains lacked capacity to handle peak runoff.

Solution: The facilities team replaced outdated units with Zurn Z100F drains. The advanced hydraulic design improved flow, while the durable dome strainers ensured consistent water intake and clog resistance.

Outcome: After installation, ponding issues were eliminated, roof life was extended, and maintenance costs were reduced. The upgraded drainage system provided reliable stormwater control across the campus.

Conclusion

The Zurn Z100F is a dependable roof drain solution for commercial, industrial, and institutional applications. Its advanced flow engineering, watertight sealing, and robust build ensure long-lasting performance under demanding conditions. When properly installed and maintained, it delivers reliable stormwater management and protects building investments for years to come.
