ABSTRACT:
The present invention provides a pump for automatic and continuous emptying of water condensate from a dehumidifier positioned below ground level or remotely from a gravity drain. The present invention includes a small electrical pump powered by a 12 volt DC power source to prevent electrical shock, includes an on/off float switch connected with the power source, in cooperation with a flexible hose of small diameter of variable length. Condensate collected in the water collection pan is withdrawn at a preselected water level by the pump and passes through the tubing to an elevated or remote drain means or to other appropriate areas for disposal. The present invention permits continuous operation of portable dehumidifiers which would otherwise shut off when the condensate water pan fills after approximately one day's unattended use.
