How do Condensate Pumps Work?
Condensate pumps are very simple in operation. They consist of a small pump, attached to a reservoir used to collect the excess condensate. One end of the pump is then connected to the drain valve of the HVAC unit, and the other end is connected to a discharge hose or pipe, which leads to a drain, sewer, or the outside. Once the condensate reaches a certain level in the reservoir, the pump turns on and removes the water.
What Size Condensate Pump Do I Need?
Since condensate pumps only run periodically when the reservoir reaches a certain level, the pumps have very small motors, usually rated at a fraction of a horsepower. This is enough power to remove the excess condensate when necessary.
