Hello. I had condensation overflow into my HVAC drain pan. I had a technician blowout the main drain line and clean out the drain pan. The next day I checked, and can still see standing water in the main drain line, above where the pipe curves out of sight.
Is it normal to still see sitting water, or does this mean the drain line is still clogged? My guess was that the water would ideally drain away out of sight.
