Sarnadrain with U-Flow®

HEAVY-DUTY ALUMINUM DRAIN

Sarnadrain with U-Flow® is a seamless heavy-duty aluminum drain, featuring a coated flange for hot air welding of Sika® Sarnafil® membranes.

  • An aluminum strainer dome provides strength and durability, while the extra-large flange, with welded metal clips for attachment of the dome, possesses a depressed sump to allow easy drainage of water from the roof surface.
  • An extended vertical drop to the drain stem and the use of an ‘easy-to-install’ U-Flow seal add flexibility and achieves watertight mechanical connections to existing PVC or cast iron pipes.
  • Sarnadrain with U-Flow® is available in a number of diameters to accommodate project requirements.
