A condensate pump is an important part of your HVAC system. During the cooling process, an HVAC system produces condensation. Most systems depend on both gravity and a 3/4-inch drain line to direct the water to the home’s exterior. However, some installations require pumping the fluid through the attic or over other obstacles using a condensate pump.
How It Works
The unit has three main parts: the reservoir, float and pump. The parts work in unison to evacuate the condensation. As the condensation level rises in the reservoir, it lifts the float, which activates the pump. The pump forces the condensation through a drain line to the home’s exterior. As the condensation is evacuated, the float descends and shuts off the pump. Common electric condensate pumps run on 110 volts and are often plugged in to a standard wall outlet located close to the HVAC unit.
Considerations
These pumps are very reliable, but they require periodic maintenance to prevent premature failure. A condensate pump that operates incorrectly can overflow and cause significant water damage. The excess moisture can lead to unhealthy mold and mildew growth inside your home. Inspect and clean your condensate pump on a regular basis. Not only will it prolong the life of your pump, but it will also help you to determine if it is time to replace the pump. If you are apprehensive or unsure of how to clean the system, call a licensed HVAC contractor to service the system.
Disconnecting
Before removing and cleaning the pump, examine the area around it to verify that it is not leaking. If the area is wet or water has pooled around it, you need to find its source so you can make the necessary repairs. It is very important before cleaning your condensate pump to unplug it or turn off the power at the main breaker box. To clean the pump properly, you must first disconnect the PVC (polyvinyl chloride) tubing connected to its reservoir. One line runs to the HVAC unit, and the other is connected to a drain line.
Do not run the HVAC system while the pump is disconnected. Remove the pump, and place it in a suitable work area. Rinse the reservoir with clean water to remove dirt, debris or algae that may have accumulated inside.
Cleaning
Use a bottlebrush or similar tool to clean all openings where the drain lines connect. Next, remove or unclog any blockages that may have developed over time, and rinse the pump with water. To avoid unnecessary damage, do not saturate the pump motor with water.
Use compressed air to remove dirt, dust and other debris that may have accumulated around the pump motor vents. If you notice excessive algae in the reservoir — a common occurrence — place a couple of algae tabs inside before you reconnect the pump. The tabs can be purchased at most home improvement centers, and they prohibit the growth of algae. Use compressed air to blow out the drain lines that were connected to the pump.
Reconnect the drain lines to the pump reservoir, making sure to connect them in their proper places. Restore power to the pump. Pour clean water through the opening in the reservoir to activate the pump. As it evacuates the water, check for leaks and make any necessary repairs.
Many components in an HVAC system — both inside and out — require periodic service. It is wise to have your system serviced by a licensed HVAC contractor on a regular basis. Call Reliable Heating & Air when your system needs servicing.
