Buying Guide

Match pump type to task

Choose submersible sump pumps for basement drainage and dedicated sewage/effluent pumps for solids handling and effluent transfer

Check motor power and flow

Higher horsepower and GPH ratings increase discharge speed; balance power with your drain capacity and circuit limits

Prefer float or auto controls

Built-in float switches or automatic floats prevent dry-run damage and provide hands-off operation for intermittent water levels

Consider construction material

Cast-iron housings offer better durability for abrasive or heavy-duty effluent use, while lighter plastics suit clean water transfer

Verify discharge size and compatibility

Confirm outlet diameter and fittings match your existing piping to avoid costly adapters and reduce installation time
