About 46% of homes were built before 1980. Older homes often have older venting, smaller closets and shutoff valves that should be checked before install day.
74% of homes heat with utility gas, so gas water heaters with existing venting are common here.

LOCAL CONDITIONS
What’s different in Chesterfield.
Every replacement needs an expansion tank
St. Louis County's plumbing code (a changed version of the Uniform Plumbing Code) requires a listed thermal expansion tank on the cold water line within 10 feet of any new or replacement water heater. It must be labeled with the measured water pressure and the tank's pre-charge, and there must be a reachable shutoff valve within 10 feet.
