The Indirect Waste Area Funnel Drain is a heavy-duty floor funnel drain based on the Zurn Z325 indirect waste funnel, engineered for reliable wastewater discharge and back-flow protection in commercial and industrial settings. With a robust Dura-coated cast-iron body and integrated backwater valve, it’s designed to handle indirect waste from equipment such as refrigeration units, air conditioners, or industrial fixtures — helping manage condensation or overflow safely and cleanly.

Built for Safety and Long-Term Performance

Dura-Coated Cast-Iron Body — Provides strong, corrosion-resistant construction that endures frequent use, moisture, and harsh environments. 

Integral Backwater Valve with Plastic Ball Float and Bronze Bushing — Prevents backflow during surges or system pressure reversals, protecting the facility from wastewater back-ups. 

Replaceable Neoprene Valve Seat — Facilitates maintenance and prolongs service life by allowing seat replacement without full drain replacement. 

Multiple Size Options — Available in 7-inch or 9-inch funnel diameter with a range of outlet sizes (e.g., 2″–6″ no-hub connections), allowing flexibility to match different piping requirements.
