Re: Condensate Leakage
The air conditioning condensate is leaking from the a/c coil instead of running out the drain.

Possible Causes: |
1 |
Clogged Drain Pipe |
|
Frozen Coil |
|
Hole in Drain Pan |
|
Condensate Missing Drain Pan |
|
No Drain Trap (Heat Pump) |
|
Double-Trapped Drain |
CHECKOUT:
1. Identify the Source of Water
- Try to identify where the water is coming from.
- Is the water coming from the coil, from sweating ductwork or lines, or from leaking pipe joints, etc.
2. Check the Indoor Coil
- Check the indoor coil to make sure that it is not frozen.
- Even without ice on the lines, the coil can be partially frozen.
- Frozen Coil --> Turn the A/C "Off" and allow the indoor fan to stay running until coil completely thaws.
- Be prepared for large amounts of water as the coil thaws.
3. Inspect the Drain Line
- Inspect the drain line and make sure that it is properly installed & properly sloped.
- On a heat pump system with the drain on the "return-side" of the blower, make sure that the drain is trapped before any open air vents.
4. Check the Drain Pan
- Remove access panel to indoor coil.
- Inspect drain pan for standing water.
- Standing water in the drain pan above the drain outlet = Clogged Drain or Double-Trapped Drain
- Empty Drain Pan --> Pour water into the drain pan and make sure that it exits through the drain line.
- Water leaks from drain pan (doesn't overflow) = Hole in the Drain Pan
5. Examine the Coil in Operation
- If possible, observe the coil and drain while the system is operating.
- Look for water that is blowing off of the coil and missing the drain pan.
