When does a Kentucky basement floor drain need backwater protection?
If the drain is subject to backflow or back pressure, Kentucky code requires a compliant backwater valve.
The code-backed basics
Kentucky code says a basement floor drain must be connected as required, properly trapped and vented, readily accessible for cleaning, and sized for its intended purpose. It also addresses backwater valves when drains can see backflow or back pressure.
In older Lexington and Richmond basements, this matters when low drains, sewer backups, or heavy rain events have already pushed water the wrong way.
When to call
If a basement drain has backed up once, smells like sewer, gurgles, or sits below nearby fixtures, get it inspected before the next storm or sewer event.
