Plumbing in Arlington: what locals should know
Water quality
Arlington has moderately hard water which can reduce water heater lifespan over time. Consider a water softener or tankless unit with a descaling system to protect your investment.
Freeze risk
Arlington rarely freezes, but when it does, exposed pipes are especially vulnerable because homes here aren't built for cold weather. Insulate outdoor pipes and know your shutoff valve location just in case.
Material recommendation
For Arlington'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 Arlington 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.
