When the liquid in the tank reaches a designated level a float switch activates the pump. Because gravity will not move this water to a drainage system at ground level, a type of water pump known as a condensate pump is required in order to provide easy access.ĭesigned to run intermittently, condensate pumps include a collection tank where condensate (captured condensed liquid) can accumulate. A typical example of the use for a condensate pump is where the boiler has been relocated to a basement. Call Reliable Heating & Air when your system needs servicing.What is a condensate pump and why might I need one?Ĭondensate pumps are a type of centrifugal pump that is used to collect and disperse the hot water and liquid produced by condensation from heating systems, such as gas and oil condensing boilers, from the production of refrigerated air, such as air conditioning and refrigeration systems, air dehumidifiers and evaporators, and the steam produced by heat exchangers and radiators. It is wise to have your system serviced by a licensed HVAC contractor on a regular basis. Many components in an HVAC system - both inside and out - require periodic service. As it evacuates the water, check for leaks and make any necessary repairs. Pour clean water through the opening in the reservoir to activate the pump. Reconnect the drain lines to the pump reservoir, making sure to connect them in their proper places. Use compressed air to blow out the drain lines that were connected to the pump. The tabs can be purchased at most home improvement centers, and they prohibit the growth of algae. If you notice excessive algae in the reservoir - a common occurrence - place a couple of algae tabs inside before you reconnect the pump. Use compressed air to remove dirt, dust and other debris that may have accumulated around the pump motor vents. To avoid unnecessary damage, do not saturate the pump motor with water. Next, remove or unclog any blockages that may have developed over time, and rinse the pump with water. Use a bottlebrush or similar tool to clean all openings where the drain lines connect. Rinse the reservoir with clean water to remove dirt, debris or algae that may have accumulated inside. Remove the pump, and place it in a suitable work area. One line runs to the HVAC unit, and the other is connected to a drain line.ĭo not run the HVAC system while the pump is disconnected. To clean the pump properly, you must first disconnect the PVC (polyvinyl chloride) tubing connected to its reservoir. It is very important before cleaning your condensate pump to unplug it or turn off the power at the main breaker box. If the area is wet or water has pooled around it, you need to find its source so you can make the necessary repairs. Disconnectingīefore removing and cleaning the pump, examine the area around it to verify that it is not leaking. If you are apprehensive or unsure of how to clean the system, call a licensed HVAC contractor to service the system. 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. Inspect and clean your condensate pump on a regular basis. The excess moisture can lead to unhealthy mold and mildew growth inside your home. A condensate pump that operates incorrectly can overflow and cause significant water damage. These pumps are very reliable, but they require periodic maintenance to prevent premature failure. Common electric condensate pumps run on 110 volts and are often plugged in to a standard wall outlet located close to the HVAC unit. As the condensation is evacuated, the float descends and shuts off the pump. The pump forces the condensation through a drain line to the home’s exterior. As the condensation level rises in the reservoir, it lifts the float, which activates the pump. The parts work in unison to evacuate the condensation. The unit has three main parts: the reservoir, float and pump. However, some installations require pumping the fluid through the attic or over other obstacles using a condensate pump. Most systems depend on both gravity and a 3/4-inch drain line to direct the water to the home’s exterior. During the cooling process, an HVAC system produces condensation. A condensate pump is an important part of your HVAC system.
