Mountain View's moderate water hardness and booming ADU construction drive combo drainage issues shaped by mineral buildup and secondary-structure plumbing quality. Ranch homes built around 1965 in Cuesta Park, Rex Manor, and Old Mountain View have standard residential drain infrastructure, but City of Mountain View blended water at 250 TDS deposits mineral residue inside drain pump housings over time.
