Florida’s climate, water quality, and housing stock create specific plumbing issues that appear consistently in inspection reports. Here’s what to watch for.
Polybutylene Pipe
Polybutylene pipe — a gray plastic pipe used widely in Florida construction from the 1970s through mid-1990s — is known to fail and is not covered by most homeowners insurance policies. Many homes built in this period still have it. Identification involves looking for gray plastic supply lines (versus copper or white PVC) at fixtures, under sinks, and at the water heater.
Galvanized Steel Corrosion
In older Florida homes, galvanized steel pipes corrode from the inside out — reducing water pressure, discoloring water, and eventually failing. Inspectors check water pressure at fixtures and look for visible corrosion at exposed connections. Replacing galvanized supply lines is a significant renovation project but improves water quality and pressure immediately.
Water Heater Age and Condition
Florida’s hard water accelerates water heater wear. Inspectors document age, check the pressure relief valve, and look for corrosion or sediment buildup. A water heater over 10 years old in Florida is approaching or past its useful life. Many insurers won’t cover homes with older water heaters.
