Generated explanation

The illustration shows a toilet above a wood floor assembly in a sectional view. The toilet outlet connects through an elbow and horizontal drain branch to a vertical soil stack penetrating the floor and ceiling. Callouts identify rot beneath the toilet and water damage at the ceiling near the stack penetration. The annotation emphasizes that wood subflooring, joists, and beams around toilets are particularly susceptible to rot, with shower stalls also noted as common locations.
