Liberty 404 Residential Drain Pump – Short Profile, 1/3 HP, 115V

Compact, ready-to-install design

The Liberty 404 residential sink drain pump system blends compact engineering with reliable performance. Factory pre-assembled and ready to install, it fits tight spaces thanks to a short profile that rises about 11 inches tall. With 1-1/2 inch inlet, outlet, and vent connections, it accommodates standard residential plumbing, and the included 10-foot power cord offers flexible placement near your sink.

Key materials include an aluminum pump body, a plastic impeller, and a polyolefin basin. The basin holds up to 4.3 gallons, with a diameter of 13-3/4 inches and a height of 11-1/8 inches, providing sufficient capacity for routine drainage while keeping the unit compact enough for under-sink installation. The 1-1/2 inch drain sizing aligns with common residential drains, helping simplify installation in existing plumbing layouts.

Smart functionality for everyday use

Automatic operation is triggered by a tether float switch, with a piggyback electrical connection for straightforward wiring. An integrally molded rubber gasket forms a gas-tight seal to help minimize odors and leaks, while the 1/3 horsepower motor on 115 volts delivers dependable performance for typical household drainage tasks.

Performance snapshots show up to 38 gallons per minute at 5 feet of head, 25 gpm at 10 feet, and 15 gpm at 15 feet. This range supports steady drainage during everyday use, with a basin that provides buffering capacity while the pump activates. The system runs on 115V and draws around 5 amps, suitable for standard home outlets. Real-world setups often place the unit near a utility or basement sink, taking advantage of compact footprint and flexible routing options to keep spaces clean and efficient.

Real-life scenarios include upgrading a utility sink in a laundry area, supporting a basement workshop, or outfitting a compact bathroom sink where space is at a premium. The combination of easy installation, automatic operation, and a durable component mix makes the Liberty 404 a practical option for homeowners seeking a reliable drain solution without extensive remodeling.
