Possible Causes:
The unit may not actually be leaking. Water vapour from the air may be condensing at the base of the unit as the room temperature drops.
Solution:
Test the unit by putting water in the tank and leave it turned off for 24 hours. If no water appears at the base of the unit, then the water build up is most likely caused by condensation.
Humidity is a measure of water absorbed into the air. Warm air holds more water than cold air. If humid warm air cools, water may condense from the air onto the floor or walls and windows. Think of dew in your yard or your bathroom mirror after a shower.
