The metal vent pipe on a gas water heater rusts from the inside out, and a rusted vent can leak exhaust into the home. It is a safety issue that deserves a prompt look.
The rust
Exhaust gases contain moisture and acids that corrode the vent pipe over time, especially at the joints and the horizontal runs.
The leak
A rusted-through vent lets carbon monoxide and moisture escape into the space around the heater.
The sag
A vent that sags or separates at a rusted joint is no longer sealed, and the exhaust takes the path of least resistance.
The replacement
Rusted vent sections are replaced, and the run is checked for proper slope and support. freezing winters put stress on exposed lines, and many older homes still have aging galvanized pipes In Baltimore, humid conditions speed the rust.
The look
Inspect the vent pipe during every heater service, because rust starts small and spreads. A rusted section is replaced before it leaks exhaust.
