Ac condensate drain line diagram.

Check for lint or crud blocking the opening to the condensate drain line inside the unit. Carson dunlop associates sketches left illustrate both acceptable and not recommended locations for the discharge of an air conditioner or heat pump condensate drain line discharge. At split system air conditioners heat pumps. Collected in a drain pan below the cooling coil as illustrated in figure 1 the water must be removed to prevent damage and contamination to the air handler system and building draining water from a condensate drain pan is not a simple process.

In new homes city codes require drain lines from the air conditioner s condensate line which are often located in the attic to tie in or be plumbed to the home s plumbing system. Typically those 3 4 pipes are plumbed into a bathroom sink s drain that is on average 1 1 4 or 1 1 2 in diameter. That white line is the condensate drain headed from the wall mounted unit not shown to outdoors. The secondary line is considered a backup line so that if the primary line gets clogged the condensate water will then go through the secondary line.

One is the primary condensate line that is generally connected to a location like a tail piece of a bathroom sink drain piece. Condensate switches imc 307 2 3 states that all hvac equipment that produces condensate must have either a secondary drain line or a condensate overflow switch a secondary drain pan with a secondary drain line or condensate switch or some combination of these installations should be used to prevent overflow if the primary drain line blocks.
