Due to the high mineral content of water in the San Antonio area, sediment build-up is still a concern even with tankless water heating systems. Heat causes calcium and other minerals to separate from the water, producing a scaly white buildup on your fixtures and a mineral buildup within your tankless system. The tankless water heater experts at Roadrunner Plumbing can perform routine maintenance, flushing your tankless system to remove mineral and sediment buildup inside the unit to keep your hot water flowing!
