Where is condensate drain line?
Your air conditioner has a condensate drain line that runs from the indoor unit to the outside of your home. You’ll find a white PVC or copper pipe located near your outdoor unit—this is where the drain line ends.
How deep should a condensate drain trap be?
If a unit were to be operating at minus 6 inches WC maximum negative plenum pressure then the trap height, per the guidelines shown in Figure 1a, requires 7 + 3½ + 1½ + 1 inches of height from under the floor or about 13 inches below the floor level.
How do you solve common problems with condensate traps?
Depending on the type of trap in use, it can be blown dry with every cooling cycle leading to more problems inefficiency. The best way to resolve these problems is by contacting your HVAC technician to have the condensate drains cleaned and flushed.
Can condensate drain to sewer?
Most condensate drains tie into the home’s sewer line and are equipped with a U-shaped trap to keep sewer gas odors from entering the HVAC system. If you notice a noxious odor coming from the supply vents when the blower is running, a dry drain trap may be the culprit.
What causes condensation in an air conditioner drain?
Check for a clogged A/C condensate drain line trap. One of the most common causes of air conditioning or heat pump condensate leakage and overflow is a clogged condensate drain line trap. And if the secondary or emergency condensate handling system is absent or defective, the result can be costly leak damage to the equipment or to the building.
When does condensate begin to drain from the fan?
Condensate drain pan H/2 minimum Sea level when condensate begins to drain off H = Fan inlet pressure (in. W.C.) + 1 in. Fan inlet pressure (negative) H FIGURE 3. Trap for draw-thru unit, condensate beginning to drain away.
What is the mechanical code for condensation drains?
Here is an excerpt from the Uniform Mechanical Code pertaining to the disposal of air conditioning condensate:
Can a condensate drain line be routed through a wall?
A flexible plastic condensate drain line may be routed through building walls, ceilings, floors, at some installations such as split system wall-mounted air conditioners and heat pumps. at SPLIT SYSTEM AIR CONDITIONERS & HEAT PUMPS we describe the routing, slope, and protection from damage for in-wall condensate drain lines.
Where are the condensate drains on a central air unit?
When the evaporator coil and drain are located in the attic, it is recommended or required by local code to have two condensate drains. The first drain pan is the known as primary drain pan and the secondary drain pan is known as the auxiliary drain pan. The primary drain pan is within the air handler; it is underneath the evaporator coil.
