Water heaters work hard every day to provide hot water for cooking, cleaning, bathing, and laundry. However, many homeowners don’t realize that routine water heater maintenance, including flushing the tank, is essential to keeping the system running efficiently. If you’re wondering how often your water heater should be flushed, homeowners in Fort Smith and Van Buren can benefit greatly from understanding this simple but important service.
According to the U.S. Department of Energy, sediment buildup inside water heaters reduces efficiency and shortens equipment lifespan.

Knowing when to flush your water heater—and when to call a professional—can prevent breakdowns and unexpected disruptions.
Why Water Heater Flushing Is Important
Over time, minerals and sediment naturally settle at the bottom of your water heater tank. This is especially common in areas with hard water, which many River Valley homeowners experience.
What Happens When Sediment Builds Up
Reduced heating efficiency
Longer recovery times for hot water
Higher energy usage
Rumbling or popping noises
Overheating of internal components
Premature tank failure
The USGS explains that mineral-rich water contributes to scale buildup in plumbing systems.

Flushing removes this sediment and helps the system operate properly.
How Often Should a Water Heater Be Flushed?
Standard Recommendation
Most manufacturers and plumbing professionals recommend flushing your water heater once per year.
Annual flushing:
Removes sediment buildup
Maintains efficiency
Extends the lifespan of the unit
Helps identify early issues
Homes That May Need More Frequent Flushing
Some households may benefit from flushing every 6–9 months, especially if they have:
Hard water
Older plumbing systems
Large households with heavy water usage
Older water heaters
A professional plumber can determine the best schedule for your home.
Signs Your Water Heater Needs to Be Flushed
If you’re unsure whether your system needs maintenance, watch for these warning signs:
Noises Coming From the Tank
Popping, cracking, or rumbling sounds often indicate sediment heating and hardening at the bottom of the tank.
Inconsistent Water Temperature
Sediment interferes with heating elements, causing fluctuating water temperatures.
Reduced Hot Water Supply
If hot water runs out faster than usual, sediment buildup may be limiting tank capacity.
Cloudy or Rusty Water
Discolored water can indicate sediment or corrosion inside the tank.
Higher Energy Bills
The Energy.gov website notes that inefficient water heaters consume more energy.

Tank vs. Tankless Water Heater Maintenance
Traditional Tank Water Heaters
Tank-style systems require regular flushing to remove sediment and protect internal components.
Tankless Water Heaters
Tankless units also need periodic flushing to remove mineral scale from heat exchangers, though the process is different.
Regardless of system type, professional maintenance is essential for safe and effective operation.
DIY Flushing vs. Professional Water Heater Maintenance
Some homeowners attempt to flush their water heaters themselves, but this process can be risky without proper training.
Risks of DIY Flushing
Burns from hot water
Improper valve handling
Incomplete sediment removal
Damage to heating elements
Missed signs of corrosion or leaks
The EPA emphasizes the importance of proper water system maintenance to prevent leaks and damage.
