Plumbing in Miami: what locals should know
Water quality
The water in Miami is on the harder side. You may notice mineral spots on fixtures. For water heaters, this means flushing the tank annually is essential to prevent sediment buildup.
Freeze risk
While freeze events are rare in Miami, they can catch homeowners off guard. The 2021 winter storm showed that even warm-climate homes need basic freeze protection for exposed pipes and outdoor fixtures.
Material recommendation
For Miami's hard water, PEX piping is ideal — it doesn't corrode or develop pinhole leaks like copper can in mineral-rich water. It's also the most cost-effective option for whole-house repiping.
Local tip
Homes built in Miami during the 1970s-80s often have copper pipes that may be developing pinhole leaks after 40+ years. If you're seeing green staining at joints, it's time for an inspection.
