When to Replace B-Vent

B-vent pipe should be inspected regularly for rust, corrosion, separation at joints, and proper pitch. If you see rust flakes, white corrosion deposits, or moisture staining around vent connections, it is time to replace. Damaged venting can allow carbon monoxide to leak into living spaces — do not ignore signs of deterioration.

Frequently Asked Questions

What is the difference between B-vent and single-wall vent pipe?

B-vent (Type B) is double-wall pipe with an air gap between the inner and outer walls for insulation and safety. Single-wall pipe has no insulation and requires greater clearance to combustibles. B-vent is required for most vertical venting installations through attics and roofs. Code requirements vary, so consult your local building codes.

What size B-vent do I need?

The vent size must match or exceed the flue collar on your appliance. Check the installation manual or the flue outlet on your furnace or water heater. Never reduce the vent diameter below what the appliance specifies. Our staff can help you plan your vent run if you bring in your appliance specs.
