Condensate Pump

Air conditioners have become an irrevocable part of our lifestyle today. They are present in most households and tend to operate for a large portion of the day. The air condensate pump system within the air conditioning unit is crucial in ensuring optimal performance. The setup works directly with the condensate water produced by the cooling system inside the device and hence requires cleaning and maintenance to prevent leaks or faults in your air conditioning. Here we present five powerful tips to clean the condensate pump perfectly for the best results.

Understanding The Workings of The Condensate Pump  

To understand the best practices to clean your condensate pumps, let us briefly cover how the system works. The condensate pump are a critical organ of any HVAC system. During the cooling process, condensation occurs within the device that requires removal to the house’s exterior. Typically, the design relies on gravity and a drainage pipe protruding outside the device for this process. But specific systems may use a condensate pipe to transfer the water from within the device to the environment. This way, water does not accumulate inside the device, which could have devastating consequences.  

A condensate pump has three parts, namely the reservoir, the pump, and the float. When condensation increases in the reservoir, the float starts to lift, which activates the pump to remove the excess water using the drain line. While the system works perfectly well, regular cleaning is required to eliminate any accumulated dirt or substances that could interfere with the flow.  

  1. Start By Inspecting for Leaks  

One of essential steps to pursue before beginning proper cleaning of the condensate system is to look for leaks. Typically leaks in the system could cause water to drip through the ceiling or walls. But in some cases, the damage may not be visible externally. Close inspection will help you understand the damage, if any, and the extent of it. If the surface of the system is moist or you find water accumulated over the area, chances are there is a leaking point. You should immediately look for the source of water or leakage.  

A simple method to test leakages is by filling the reservoir with water. Now connect the plug and check if the draining begins when the reservoir fills up. Also, look for water leakage points during this process to know what needs fixing.  

  1. Try A Clean Up with Vacuum 

Turn off your AC. Now, locate the drain line, typically a PVC pipe attached to the wall running from your AC`s evaporator coil. It must be near your outdoor unit. In most cases, the drain line is a T-shaped vent with a cap or cover. You can easily remove this cover to look inside for blockages. 

A simple method to clean up dirt or clogging here is a vacuum. Remove the paper filter from a wet/dry vac and connect the sucking attachment to the drain line. You can secure it with duct tape to ensure smooth cleaning. Now switch on the vacuum for a few seconds to help clear the drain. 

  1. Try Cleaning with Bleach  

In some cases, the accumulated gunk may be challenging to remove with a vacuum. Also, given water flows through the part regularly, the line may contain sticky dirt that may require better cleaning methods. Bleach might be a competent solution to this problem.  

Add half part warm water and half part bleach to a cup. Open the drain line and pour this mixture into it. Let the mixture sit for a few minutes. You can now empty the drain. Repeat the process with water.  

The best way to ensure optimal benefits from this process is to have the bleach fill the reservoir and activate the pump to come out through the exit tube. This step can help remove all the oil gunk from the complete system. But beware, bleach can interact with metal pipes and drain pans connected to your AC that could damage them. 

  1. Consider The Vinegar Treatment  

While bleach is a good choice for cleaning the condensate pump, it does come with certain disadvantages, such as causing damage to metals in the system. Vinegar is the way to go around this problem and still get the dirt out. Using a part vinegar solution to clean the drainpipe can eliminate dirt, gunk, algae, microbial growth, mildew, and any other buildup blocking the pipe. 

 Add ½ cup white vinegar into the drain line from the cap opening. Let it sit for a few minutes before draining out. Always follow up with a cleansing wash using hot water or dish soap to remove the strong vinegar smell.  

  1. Newer Systems May Just Need Some Hot Water  

Several new systems recommend not using vinegar, bleach, or other cleaning agents in the drain. Instead, you can use hot water to clean up the clog. In this case, you may need to increase the frequency of cleaning from one every three months to once every fortnight to achieve the best results.  

Conclusion 

A golden rule for extending the life of any electronics in your home is remembering to follow up on proper maintenance at regular intervals. The critical steps involve cleaning, pampering, and changing parts of the system that go through everyday wear and tear. While the process might feel tedious, you may grow to realize how much this simple step can improve the performance efficiency of your electronics overall.
