A master plumber registers with the City by showing a Texas Master Plumber's license and proof of insurance. If you'd rather do the job yourself, the City sells a homeowner's permit, and with it you're the one who schedules each inspection. Hardness in Houston Water's 2024 water quality report averages 110 ppm as CaCO3, inside a range of 43.4 to 137 ppm. That report also says the City is inventorying service lines in each of its six distribution systems, and it offers free lead and copper tap testing to qualified homes.
