Hvac Condensate Drain Line Trap

That is why in the summer your car drips water.

Hvac condensate drain line trap.

All air conditioners have a special drain for this condensation. A for the installation of a trap in accordance with the unit manufacturer s installation and operating instructions. While most manufacturers don t specify this on this gravity ductless drains it is something to look out for. The condensate drain line connected to your ac unit plays a vital role in the effective operation of your entire system.

The drip pan connects to the condensate drain line which carries water out of the home. A p trap serves a very important purpose on an a c unit. Air conditioning units pull a lot of water out of the air. The imc states that condensate drains should be trapped according to manufactures specs however wording was added in imc 307 2 4 1 that states that ductless systems must either have a check valve or a trap in the condensate line.

This will kill any algae mold or mildew that has formed in the pipe. 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. If the condensate drain line is clogged you will need to use a wet dry vacuum or a special pump to unclog the line. The only code requirements for drain lines removing condensate from hvac equipment are.

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. A central air system routes condensation through a u shaped trap located in the drain line just outside the air handler. B that the drain lines slope toward the final drainage point at a rate of 1 8 inch per foot. When the drip pan becomes full or clogged or the condensate line is clogged water can spill over the drip pan s edges onto the floor surrounding the unit.

It s similar to the trap under your kitchen or bathroom sink. 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. See when moist air hits something cold the water condenses out of the air and collects on the cold surface.
