The intense heat and low humidity in summer cycles stress copper and PVC pipes through constant expansion and contraction, while our alkaline water accelerates corrosion and mineral buildup—especially problematic in the 78613 and 78729 zip codes where many homes tap into older limestone-laden well systems. Underground pipes running through Cedar Park's clay-heavy soil face additional pressure from ground settling during our dry season, which can crack or misalign joints.

We regularly see pinhole leaks in 1980s-era copper piping, slab leaks from pipes embedded in concrete foundations (common in the Lakeline and Whitestone neighborhoods), and corrosion failures where older galvanized steel was never replaced during renovations. Mineral deposits also clog supply lines faster here than in lower-mineral areas, and landscape irrigation systems frequently develop leaks that homeowners attribute to water waste rather than actual pipe failure.

Before calling for a full replacement, ask about a water quality test—if your water hardness is above 300 ppm (common in Cedar Park), installing a whole-home filter system or softener can extend your remaining pipe life by years and prevent future leaks. Also, if your home was built before 1990, get an inspection specifically for galvanized or polybutylene pipes; the latter was a class-action lawsuit material and fails catastrophically, while galvanized will start failing soon if it hasn't already.

June through August is when slab leaks become most apparent because the dry, hot ground draws moisture from any crack in your foundation's plumbing—watch your water meter in summer; if it climbs without explanation, don't wait. Winter isn't freezing here, but our freeze-thaw cycles in January and February still cause micro-fractures that develop into leaks by spring, so any visible corrosion or stains should be addressed before summer heat makes them critical.
