Components of a Furnace Water Pump

A furnace water pump typically consists of three main components:

  1. Reservoir: Collects the condensation produced by the HVAC system.
  2. Float: Rises as the condensation level increases, triggering the pump to activate.
  3. Pump: Activated by the float, it pumps the condensation through a drain line away from the HVAC system.
