How Often Should My Water Heater Be Flushed?


Water heaters, the unsung heroes of our homes, consistently provide us with warm showers, clean dishes, and laundered clothes. To ensure they function efficiently and last as long as possible, regular maintenance is essential. One crucial maintenance activity is flushing the water heater. But how often should this be done?

Water Heater

Why Water Heater Flushing Is Important

Before diving into frequency, let's understand why flushing a water heater is necessary. Over time, minerals and sediments from the water accumulate at the bottom of the tank. This sediment buildup can cause multiple problems:

  1. Reduced Efficiency: The sediment layer can act as a barrier, making the heater work harder to warm the water, leading to increased energy bills.

  2. Shortened Lifespan: The extra effort required due to sediment buildup can cause the heater to wear out faster.

  3. Noisy Operation: The heating and reheating of sediment can cause popping or rumbling sounds.

  4. Water Discoloration: Accumulated minerals can lead to rusty or muddy-looking hot water.

Flushing Frequency

The frequency of flushing depends on a few factors:

  1. Water Hardness: Homes with harder water will need more frequent flushing due to a higher mineral content.

  2. Water Heater Usage: A household with high hot water usage might need to flush their heater more often.

  3. Water Heater Type: Tankless water heaters have different maintenance needs than traditional tank-style heaters.

As a general rule, for households with moderate water usage and average water hardness:

  • Traditional tank-style water heaters should be flushed at least once a year.

  • Tankless water heaters might require more frequent inspections, and the unit flushed as recommended by the manufacturer, often every 6 months to 2 years.

The Flushing Process

Flushing your water heater involves draining the tank to remove any sediment. If you're a seasoned DIY enthusiast, you could follow the manufacturer's instructions to do this yourself. However, for optimal results and safety, it's recommended to hire a professional plumber. They'll ensure the job is done efficiently and safely, checking other components like the pressure relief valve and heating element during the service.
