The Zurn Z105 Control-Flo Roof Drain is specially designed for dead-level roof installations where controlling water buildup is crucial. With its built-in weir, sturdy construction, and debris protection, it helps maintain roof integrity, reduce risk of overflows, and ensure safety in large commercial and industrial roofing systems.

Key Features

Flow-Restricting Parabolic Weir: Controls water flow by limiting capacity to around 10 gallons per minute (GPM) for each inch of water above the drain body, helping manage runoff in shallow roofs.
Robust Cast Iron Body: Heavy-duty, Dura-Coated finish provides corrosion resistance and durability in demanding rooftop environments.
Integral Membrane Flashing Clamp & Gravel Guard: Secures roofing membrane to ensure waterproofing, while the guard prevents gravel and debris from clogging the drain.
