Liberty Pumps 404 1/3 HP Drain Pump
The Liberty 404 is a compact, low-profile drain pump built for tight spaces where gravity drainage isn’t feasible. Its short height allows fixtures to be installed below drain lines while keeping reliable performance intact. The 404 is ideal for gray wastewater from laundry trays, bar sinks, washing machines, or basement remodels.
