The Watts FD-880 is a purpose-built ground-water containment drain designed for exterior or splash-zone applications where excess subsurface water and surface runoff must be managed simultaneously. Featuring an epoxy-coated cast-iron body with a membrane clamp, the unit includes a 4″ diameter ABS perforated standpipe for subsurface drainage and an 8″ diameter fixed top with heel-proof ductile-iron grate for surface flow capture.

Key Features

• Epoxy-coated cast-iron construction with membrane clamp for durability and seamless floor finish integration

• Integrated 4″ ABS perforated standpipe for subsurface water interception

• 8″ fixed top with heavy-duty heel-proof ductile-iron grate for high-traffic surface applications

• Flexible outlet options (no-hub standard, push-on, threaded, inside-caulk) for installation adaptability

• Suitable for heavy commercial traffic zones and designed to control both surface and subsurface drainage loads
