Hard Water Mineral Buildup Inside Drain Lines
Las Vegas Valley water from Lake Mead is among the hardest municipal supplies in the United States, consistently measuring 17 to 24 grains per gallon. Calcium and magnesium dissolve into the water at the source and deposit on every interior surface the water contacts, including drain pipe walls. Over 16 to 25 years of daily water use in an Aliante home, this mineral layer narrows the pipe interior, reduces flow capacity, and creates a rough surface that grease, hair, and soap scum bond to much more aggressively than they would in a newer or cleaned pipe. Store-bought chemical treatments dissolve some of the clog material but rarely address the mineral layer driving recurring blockages.
