A vent stack is the vertical pipe that runs from the drain system up through the roof. It equalizes air pressure so drains flow and traps keep their water seal. In older Bradenton homes the stack is often cast iron inside a wall.
Cast iron stacks crack along a seam or rust through, especially near the roof where rain gets in. The fix is to cut out the bad section and replace it with PVC, or replace the full stack, with the roof flashing resealed.
Florida sun and heavy summer rain wear roof flashing around vent pipes. Water that enters at the flashing runs down the cast iron stack and speeds up rust inside the wall.
