Liberty Pumps K001155 Float Switch for Pump 404
A replacement float switch used to control automatic on/off operation of the Liberty Pumps Model 404 drain pump system based on liquid level in the tank.
Key Features:
- Replacement part listed by SupplyHouse as "Float Switch for Pump 404" (Application: Replacement Part)
- Designed to restore automatic pump control when the original Model 404 float switch is worn, damaged, or failing
- Liberty's Model 404 system design uses an internal float switch with a separate access cover (QuickTree) for inspection/service
Compatibility & Applications:
- Intended for Liberty Pumps Model 404 applications only (per published Q&A guidance for this part)
- Used in gray wastewater drain pump systems where the Model 404 is installed (e.g., laundry tray sinks, bar sinks, washing machines and similar drainage below gravity lines, as described for Model 404)
- Must only be used in applications where the manufacturer specifies this exact part number: K001155
Installation & Operation Notes:
- Installation should be performed by a qualified pump service professional or experienced installer
- Always disconnect power before servicing; follow the Liberty Pumps Model 404/405 installation manual and any service documentation for the specific unit
- Liberty's installation manual notes the 404/405-series use a float switch cord with a series (piggyback) plug to interconnect the float switch and pump cords for automatic operation; the design can allow temporary manual operation by bypassing the switch (follow the manual's safety and operating instructions)
Maintenance & Troubleshooting:
- Liberty's manual recommends routine checks to confirm free, unobstructed float switch movement and good switch condition
- Common failure symptoms tied to float-switch issues include: pump will not run automatically, intermittent cycling, or the pump runs when the motor cord is powered directly but not when controlled through the float switch
- Troubleshooting and replacement decisions should follow the Liberty Pumps installation/service documentation for the Model 404 system
User Reviews & Q&A Summary:
- Reviews consistently describe this as an exact-fit/OEM-style replacement that restores normal operation without replacing the entire pump system
- Common theme: quick, straightforward swap (often described as a short install) with the pump returning to normal automatic cycling
- Customers frequently mention successful repairs on older Model 404 installations and appreciate being able to fix the issue by replacing the switch
- Q&A themes emphasize compatibility: this switch is for the 404 (not confirmed for other models like 405HV), and Liberty replacement switches are model-specific rather than universal "inline" level controls
