Plumbing in Modesto: what locals should know
Water quality
Hard water in Modesto can shorten water heater life and reduce efficiency. Annual tank flushing helps, but a water softener is the best long-term solution for protecting all your plumbing fixtures.
Freeze risk

Local tip
If your Modesto home was built before 1960, there's a good chance it has original galvanized pipes. These typically last 40-60 years, meaning many are past their lifespan. Watch for discolored water and low pressure as warning signs.
