Air Conditioning Ac Condensate Drain P Trap

Air conditioning units pull a lot of water out of the air.

Air conditioning ac condensate drain p trap.

A p trap serves a very important purpose on an a c unit. Ultimately your condensate line is responsible for removing the condensation that s produced by the evaporator coil draining it from the air handler to the outside of your house. Condensate traps exhibit many failure modes that can impact on indoor air quality. Air was coming in from the outside and creating a dam which was preventing the condensation from going out of the a c and.

The absence of a properly working p trap could push unfiltered air into your home and cause an overflow of the condensate drain. P traps have to be installed on a suction system so a p trap was added. I have a forced air furnace air handler in my basement with a standard a c unit condenser out side a c coil in the main supply truck about a couple inches over the furnace air handler. The condensate drain line connected to your ac unit plays a vital role in the effective operation of your entire system.

The condensate line comes out of the main trunk and runs to the floor just above the drain near the furnace. The slow dissolving enzyme gel will outperform and outlast conventional tablets and strips. That is why in the summer your car drips water. A central air system routes condensation through a u shaped trap located in the drain line just outside the air handler.

See when moist air hits something cold the water condenses out of the air and collects on the cold surface. Condensate drains typically have traps which are designed to keep air from moving in or out of the air handler without preventing condensate drainage. It s similar to the trap under your kitchen or bathroom sink. It coats the pan p trap and drain piping with a lubricative film to improve flow and prevent future soil adhesion.

In our opinion and as we discuss in these articles while a trap on a condensate drain line usually provided quite close to the condensate collection pan itself can reduce the chances of sewer gases backing up from a condensate drain that has been connected to the building dwv vent piping not a procedure we recommend a conventional p trap in the condensate drain will not protect against all sewer gas backup possibilities.
