Presently most plumbing codes call for the use of a p trap on all appliances that are connected to a sanitary sewer.

Ac condensate line p trap.

A p trap serves a very important purpose on an a c unit. P traps have to be installed on a suction system so a p trap was added. Trap failures due to freeze up drying out breakage blockage and or improper installation can compromise the seal against air ingestion through the condensate drain line. Schedule 40 dwv plastic condensate p trap features a 1 piece design.

There is a major difference between using p traps on sanitary applications and condensate removal from an ac unit and that is the latter has a pressure within the drain pain. That is why in the summer your car drips water. See when moist air hits something cold the water condenses out of the air and collects on the cold surface. The condensate p trap is white and is constructed of schedule 40 dwv plastic.

Air was coming in from the outside and creating a dam which was preventing the condensation from going out of the a c and. Condensate drains typically have traps which are designed to keep air from moving in or out of the air handler without preventing condensate drainage.
