Condensate Drain Line – Tips

If it’s not the thermostatic shower valve it’s something else, are we right? Clearing your air conditioner’s condensate drain line can prevent problems with your unit and have a positive impact on the efficiency of the system’s operation. When you don’t routinely clear the condensate drain line, you’re allowing the perfect breeding ground for mold and bacteria to form. After a while this can cause elevated humidity, waste damage and musty odors inside your home.

Vinegar is the best/easiest way to clear your AC condensate drain line without calling for HVAC technicians.

Requirements To Clear Your Condensate Drain Line With Vinegar

  • Rags
  • A wet and dry vacuum
  • Distilled water
  • A Funnel

Steps To Clear Your Condensate Drain Line

  1. Shut down your air conditioner. Turn off the AC unit at the thermostat and also at the breaker.
  2. Locate your condensate pan. The pan is often situated directly under AC unit.
  3. Identify the access point on the condensate drain line and flush with distilled vinegar.  A number of drains have a T-shaped vent tee with a cover. Take off the cover at the top of the drain and look for blockage.
  4. Use this port to flush the condensate drain line with a quarter cup of distilled vinegar. Use peroxide or hot water and a drop of dish liquid to delicately clean off the remaining debris in case you don’t like the odor.
  5. Allow the solution to stand for half an hour. Finish the cleaning by flushing the pipe with water. You should have someone on the other end of the pipe to watch and inform you if the water is flowing freely.

In case you’re in possession of a shop vacuum, you can make use of surgical tubing to open the blockage. This technique doesn’t function effectively in the event that your condensate drain line has sharp turns that are susceptible to clog up.

Make use of the opening on the edge of the drain pan in case your system doesn’t contain an access vent. Underlying complications with the system can also be responsible for compromised water flow. When the pan and drain are not slightly tilted, water can accumulate in behind the pan and will ultimately overspill. Several fresh systems are set with overflow detectors fitted within the pipe.

I recommend you call a local professional if you are not in a position to clean your AC’s condensate drain line. Constant periodic measures such as inspecting your drain line can help increase your AC’s efficiency. The clearing process should be repeated each month to destroy any harmful bacteria or buildup, ensuring peak performance operation.
