Liberty Sink and Drain Pump Systems
Liberty sink pump systems collect and pump grey water from sinks, showers, washing machines, and floor drains in locations where gravity drainage to the main waste line is not available. These compact systems fit under counters, behind walls, or in tight mechanical spaces and pump grey water up and over to the nearest sewer connection.
The most common applications are basement wet bars, below-grade laundry rooms, bathroom additions below the sewer line, and commercial break rooms where adding a gravity drain would require cutting concrete. The system includes a sealed collection basin with inlet connections for the fixture drains and a pump that activates automatically when the water level rises.
When selecting a sink pump system, confirm the number of fixtures connecting to the system, the type of waste (grey water only vs. sewage — sink systems are not designed for toilet waste), the vertical lift required, the horizontal run to the drain line, and the available space for the basin. For installations that include a toilet, see the Liberty toilet pump systems collection instead.
