Washington, D.C. receives water from the Potomac River, which carries moderate to high mineral content depending on seasonal conditions. This hard water accelerates calcium and lime buildup inside toilet tanks, particularly on fill valve diaphragms and flush valve seats. Properties east of the Anacostia River sometimes experience higher sediment levels that clog the small orifices in rim jets and siphon tubes. Running toilet repair calls increase during summer months when mineral concentration peaks due to lower river flow. The district's older water mains also shed iron oxide particles that stain toilet bowls and create abrasive material that wears rubber components faster than in areas with newer infrastructure.
