Liberty Pumps are used to move effluent out of a septic tank pumping chamber to a drainfield. Septic effluent pumps are used in raised bed, mound, or sand-bed filtration septic systems in which the absorption bed is located higher than the septic tank. In these installations septic effluent is pumped from a final chamber in the septic tank or from a second effluent chamber up to the absorption system. Septic tank effluent pumps are built to higher standards of durability and for more demanding service than a typical sump pumps. The septic tank effluent pump does not have to handle solid, but many solids are flushed down the toilet by mistake or negligence and a solid handling pump then becomes a plus.
