Why it matters

The Pro380 P382LE51 arrives pre-assembled: Liberty's 1/2 HP LE51 sewage pump in a 24 by 24 in basin. The shallow 24 in depth makes burial easier, and the 41 gallon capacity means fewer, longer cycles.

A separate access cover lets you reach the pump without disturbing the vent and inlet, and an anti-flotation collar keeps the basin from lifting in wet soil.
