Tankless water heater repair, installation, and descaling.

Tankless water heaters are popular in Chico, Redding, and Oroville because they take up less room and provide continuous hot water. They also have specific requirements: higher gas flow, correct venting, adequate water pressure, and periodic descaling to remove mineral buildup. A unit that is undersized or connected to an existing gas line that cannot keep up will throw error codes and deliver lukewarm water.

Attaboy Plumbing installs tankless water heaters with proper gas line upgrades, venting, isolation valves, and condensate drainage. We size the unit to your peak hot-water demand, not just the number of bathrooms, so you can run the shower, dishwasher, and laundry simultaneously without the temperature dropping.

Repair calls for tankless systems usually involve ignition failure, flame sensor issues, flow sensors, heat exchanger scaling, or error codes tied to venting or gas pressure. We diagnose the code, test the gas supply, inspect the venting, and flush the heat exchanger when hard-water scale is the cause.

Descaling is preventive maintenance, not a repair. In hard-water areas, a tankless unit should be flushed annually to maintain efficiency and warranty coverage. We isolate the unit, circulate a descaling solution through the heat exchanger, and check all filters and screens before putting it back in service.
