How Often Should You Flush a Water Heater? (Hard-Water Sacramento Edition)
Sediment is the silent killer of water heaters in our region. Here is how often to flush, descale and inspect yours to get the most years out of it.
Key takeaways
- Flush tank water heaters once a year in hard-water areas.
- Descale tankless units every 12 months.
- Check the anode rod every 2 to 3 years.
Water across much of Placer and Sacramento Counties is moderately hard to hard. Minerals settle in tanks and coat tankless heat exchangers, cutting efficiency and shortening lifespan.
Tank water heaters: flush once a year
A yearly flush removes sediment before it hardens. If your tank already rumbles, flushing may help, but on older tanks it can also stir up sediment that clogs the drain valve. We handle that safely.
Tankless water heaters: descale every year
Scale inside the heat exchanger causes error codes, fluctuating temperatures and early failure. A descaling flush with a pump and solution keeps it running like new and protects your warranty.
What professional maintenance includes
- Full flush or descaling.
- Anode rod inspection.
- T&P valve test.
- Burner and venting check.
- Gas connection and leak check.
- Temperature and pressure check.
