The DSA-25-1 Dry Strainer is a companion for Big Dipper units with flow rates up to 25 gallons per minute (gpm). The Dry Strainer simplify maintenance and reduces clogged drains caused by coarse solids build-up.

The CF-VENT-1 Carbon Vent Filter is “activated” when injected with hot air or steam, creating pores that trap odor molecules. Big Dipper Carbon Vent Filter containers are durable and reusable, and the carbon pellets are biodegradable. Each filter comes with one 9-oz. packet of replacement pellets..


*Advanced Odor Protection prevents odors from escaping through the lid of the Big Dipper but does not prevent odors related to the rest of the plumbing system including but not limited to: open floor drains, air gaps, external solids straining devices, improper venting, and odors generated elsewhere in the plumbing system.
