How to Drain a Swamp Cooler

Evaporative coolers, or swamp coolers as they are sometimes called, work by evaporating water and using the cool air produced to cool the room temperature.

You can use a swamp cooler as an alternative to air conditioners, which use refrigeration to cool air. During the colder months of the year, you will need to winterize your swamp cooler to prevent damage to the machine. The most important part of the winterizing process is draining water out of the cooler. Frozen water can damage pipes and pumps within the cooler.

Turn the swamp cooler off by pressing the power button on the control panel in your home. Then, unplug the power supply.

Turn the water source tap on the line that flows into the swamp cooler to the "Off" position to stop the water flow into the swamp cooler. The remaining water in the line will flow into the swamp cooler

Disconnect the water line from the cooler. Depending on the type of swamp cooler you own, this can be done either by hand or with the use of a wrench to loosen the connector. The water source line can stay connected to the main water line. As long as the tap is turned to the off position, no water will run through the line.

Let the water drain completely from the cooler.
