Home Inspection Flashcard #178

Roof, Vents

What's Your Call?

What is the primary defect you see in this photo?

a. A plumbing stack vent is too short.

b. Corroded flashing needs immediate replacement.

c. A combustion vent is located too close to a plumbing stack vent. The use of plumbing fixtures will pull the toxic products of combustion into the pipes from which it could enter the living space.

d. A combustion vent is installed too close to an attic opening (the ventilation fan opening). Under the right conditions, the toxic products of combustion might be pulled into the living space.
