Common Plumbing Issues in Irvine

Irvine's plumbing challenges differ from older Orange County cities. Hard water from IRWD causes scale buildup that shortens water heater lifespan and clogs aerators. Homes built in the 1970s-1980s in University Park, Turtle Rock, and Woodbridge may have original copper supply lines showing pinhole leak patterns. HOA-managed communities add complexity because plumbing work often requires management approval and coordination with shared systems.
