In this HVAC Gas Furnace Video, I go over why the pressure switch won't work with a blockage in the drain, how and why the pressure switch is connected to the drain line, what could happen if you don't clean this, why this water drain clogs, and how to fix it. I also go over the proper pitching of the drain line away from the furnace. Supervision is needed by a licensed HVACR Tech while performing tasks as Experience and Apprenticeship garners Wisdom and Safety.
