Method #9: Applying 30 PSI of Nitrogen Through an Extension Tube to Blow Out the Condensate Trap. Attach a hose and air gun to the nitrogen regulator and set the secondary regulator to 30 PSI. Add the extension tube with electrical tape on the end to the air gun. Put the extension tube down into the trap and allow the nitrogen to blow out the clog. When finished, fill the trap back up with water and replace the cap.

Method #10:

Using Pressurized Air

Through a Flexible Extension Hose

To get to hard to reach places, a small flexible extension hose can be added to the air gun. Fish the flexible hose end (poly tube end) into the open section of the condensate drain line. Cover the remainder of the opening and then apply the air/nitrogen pressure through the drain line. This method can be used when there is no service access cap or when the only access is the primary drain pan outlet

A Quick Note: Method #1 is a preferred method because not only is the clog removed, but the entire drain line can be flushed by adding water into the indoor service access cap or drain pan. Always add water back into the trap when complete! This stops any air from being pulled or pushed through the drain line and allows water accumulating in the primary pan to drain out properly.
