Omaha Home Inspection: B-vent for water heater oversized

By
Home Inspector with Foundation-2-Rooftop, Inc.

The 2 photos below are of a water heater flue pipe that is oversized.  As a result, the flue gases aren't drafting properly up and out to the atmosphere.  They are cooling off before they make it to the top, churning, and causing the B-vent to corrode.  This could also lead to backdrafting of carbon monoxide and other flue gases into the home under the right circumstances.  On a side note: notice the B-vent touching the drywall in the 1st photo and touching the wood shake in the 2nd.  It needs a minimum 1" clearance to combustibles.
