Why it matters

The Zoeller 105 drains a sink, laundry tray, wet bar, dishwasher or garbage disposal where there's no gravity drain, without breaking concrete. A 3/10 HP vortex pump passes solids up to 1/2 in, handling lint and food particles.

The basin's footprint is about 11-3/4 by 12-1/2 in, small enough for a base cabinet. A check valve is built in, and Zoeller covers it for three years.
