How to Fix / Troubleshooting
Safety: Use caution when accessing vent pipes in attics or 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: Vent should slope back toward the furnace or continuously to the termination per 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 joints re-glued.
When to call a professional: Venting corrections and code compliance should be handled by a licensed HVAC installer.
