Our Tankless Water Heater Maintenance Services
How Tankless Water Heater Maintenance Works
- System shutdown: We safely turn off the power and water supply before starting service.
- Professional flushing: Specialized pumps circulate a cleaning solution through the unit for about an hour to remove mineral buildup from the heat exchanger.
- Detailed inspection: All connections, gas pressure, and venting are checked to ensure safe and proper operation.
- Component checks: We clean or replace the water filter, inspect the ignition system, and test overall performance.
- Preventive diagnostics: Advanced tools help identify potential issues before they become costly repairs.
- Service time: Maintenance typically takes 1–1.5 hours, depending on the level of buildup.
Getting your tankless water heater serviced is pretty straightforward, but it takes the right tools and know-how to do it properly. Our technicians start by shutting off the power and water supply, then connect specialized pumps to flush cleaning solution through the system. This high-tech equipment circulates the solution for about an hour, breaking down all the mineral buildup inside the heat exchanger.
During this process, we also inspect every connection, test the gas pressure, and check the venting system for any blockages. The latest diagnostic tools help us spot potential problems before they become expensive repairs. We clean or replace the water filter, check the ignition system, and run performance tests to make sure everything is working at peak efficiency.
The whole process usually takes one to one and a half hours, depending on how much buildup we find. Most homeowners are surprised at how much sediment comes out during the flush – it’s like giving your water heater a fresh start.
