Trane Condensate in Vent Piping

Water dripping from PVC vent pipe joints or around the exhaust outlet.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Improper vent slope, Excessive vent length, Blocked vent causing condensate backup, Failed vent joint sealing

Safety: Use caution when accessing vent pipes in attics or on roofs.

Steps to check:

Visual inspection: Follow the PVC vent from the Trane furnace to the outside. Look for low spots where water could collect.
Check slope: The vent should slope back toward the furnace or continuously to the termination per the installation manual. Adjust supports if necessary.
Seal joints: If joints are leaking, they may not have been properly solvent-welded. Do not just caulk; have the joints re-glued.

When to call a professional: Venting corrections and code compliance should be handled by a licensed HVAC installer.
