St. Louis draws water from the Missouri and Mississippi Rivers, which carry high concentrations of dissolved limestone and mineral sediment from upstream watersheds. The municipal supply averages 7 to 10 grains per gallon of hardness, which qualifies as moderately hard to hard. That means every gallon deposits calcium and magnesium onto pipe walls, creating limescale accumulation in plumbing that narrows flow paths and traps rust and biofilm. Homes in older neighborhoods with galvanized steel pipes face the worst problems because rough, corroded interiors accelerate mineral deposits in water pipes. Without descaling or pipe replacement, hard water pipe scaling leads to complete blockages and emergency failures.
Peak Plumbing St. Louis has serviced homes across the Metro area, from the historic districts south of Forest Park to newer developments in West County and St. Charles. We know which neighborhoods have the oldest plumbing infrastructure and which ZIP codes report the highest mineral content. We understand local building codes for plumbing alterations and pull permits when required. That local knowledge means accurate diagnosis, code-compliant repairs, and long-term solutions tailored to the specific challenges of St. Louis water and housing stock.
