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.
