Where is the drain pipe in a central air conditioner?

A drain pipe for a central air conditioner system is generally found around or behind the location of the unit. The drain pipe is typically made using a PVC pipe that is connected into the wall of the home and is colored in either black or white.

The function of this drain pipe is to remove water generated by the functions of the air conditioner inside the home. This drain can become clogged over time due to a build up of residue or algae in its interior. A clogged drain pipe can be easily cleaned by using a wet suction vacuum cleaner.
