Nothing is more frustrating than having great cold water pressure while hot water trickles out of your showerhead. Because tankless water heaters contain narrow internal waterways, mineral scale, sediment flakes, and sticking water flow servos can severely throttle hot water volume. In Chicago Heights, Illinois, our technicians diagnose low hot water pressure. We clean inlet filter strainers, descale constricted heat exchanger tubing, replace jammed electronic water control valves, and adjust pressure regulators to restore full, invigorating hot water flow.
