Why it matters
This Little Giant system arrives preassembled: a 1/3 HP automatic pump in a 3.5 gallon polypropylene basin with piping, adapters and O-rings. It collects water from HE washers, utility sinks, dehumidifiers, AC units and water softeners.
An integral diaphragm switch starts it at 4 to 7 in and stops it at 1 to 3 in. Little Giant rates it at 2,760 GPH at 5 ft and 18 ft shutoff. The check valve, discharge pipe and union aren't included.

Good fit if

Pros and cons
Pros
- Preassembled
- Diaphragm switch
- Compact
Cons
- Check valve not included

Limitations to weigh
- Fit a check valve on the discharge so water in the pipe doesn't fall back into the pit after each cycle.
- Grey water from sinks and washers can carry lint; clean the basin filter regularly.
