Zoeller 31-0444 Sump Basin 22 gal 22 in

Sump Basin for Residential Drainage

The Zoeller 31-0444 is a polyethylene sump basin designed to collect groundwater or wastewater in residential drainage systems. Its 22 gallon capacity suits standard sump pump installations where a durable, corrosion-resistant container is required. The unit arrives new and ready for below-grade placement.

Practical Limits of a Non-Vented Design

This basin includes no vent connection and no pre-drilled inlet, so the installer must cut openings to match the specific pipe layout and local code requirements. The absence of factory ports means flexibility in pipe routing but adds labour and requires proper sealing to prevent leaks. California Proposition 65 warnings apply to chemicals in the material.

Polyethylene Construction and Daily Use

The polyethylene body resists rust, rot and chemical attack from typical sump fluids, supporting long service life in damp environments. At 22 inches overall height, the basin fits standard pit depths while allowing sufficient pump submergence. Smooth interior walls reduce debris build-up and simplify occasional cleaning.
