Multiple inlet ports allow it to handle several drain sources simultaneously — shower, sink, and condensation — from a single pump unit. An Ultima automatic float switch activates the pump when water reaches the trigger level and shuts it off when the sump is clear, with no manual intervention required.\u003c\/p\u003e\u003cp\u003eA built-in inlet screen traps hair and debris before they reach the pump, and the clear see-through lid allows quick visual inspection without disassembly.

The automatic float switch means it runs only when needed and stops on its own, which is important in an unattended bilge or sump. The clear lid and removable inlet screen make routine maintenance straightforward without pulling the pump.
