Air Conditioning Ac Condensate Drain P Trap

Condensate drains typically have traps which are designed to keep air from moving in or out of the air handler without preventing condensate drainage.

Air conditioning ac condensate drain p trap.

The absence of a properly working p trap could push unfiltered air into your home and cause an overflow of the condensate drain. It s similar to the trap under your kitchen or bathroom sink. Condensate traps exhibit many failure modes that can impact on indoor air quality. A p trap serves a very important purpose on an a c unit.

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. Viper condensate pan and drain treatment is a sprayable gel. 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.

Been looking at some posts around here and notice a lot of mention of p traps for a c condensate lines. Air conditioning units pull a lot of water out of the air. The condensate drain line connected to your ac unit plays a vital role in the effective operation of your entire system. 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.

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. The slow dissolving enzyme gel will outperform and outlast conventional tablets and strips. P traps have to be installed on a suction system so a p trap was added. 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 condensate line comes out of the main trunk and runs to the floor just above the drain near the furnace.
