Sediment buildup is one of the most common problems that can impact how well your water heater works and how long it lasts. As your tank draws in water, minerals and tiny, trace particles settle to the bottom of the tank, which forms a layer of debris that accumulates over time. Unaddressed, it may lead to issues like reduced efficiency, corrosion, and, in more serious cases, leaks or damage to the tank. Fortunately, this issue can easily be prevented by performing some simple maintenance tasks.

1. Flush Tank Annually

Flushing the tank regularly helps clear sediment buildup before it can affect your water heater’s performance. To accomplish this, first turn off the power or gas supply to the heater, then shut off the cold-water valve. Attach a garden hose to the drain valve at the bottom of the tank and run the hose outdoors or to a floor drain.

Open the valve and let a few gallons drain out until the water runs clear. Close the valve, remove the hose, turn the water and power back on, and you’re done. For more detailed instructions for flushing your specific model, refer to your owner’s manual.

2. Lower the Water Temperature

High temperature settings cause minerals like calcium and magnesium to separate from the water more rapidly, speeding up sediment accumulation. Most experts recommend a water temperature of 120°F for general household needs. However, many water heaters are set at a default temperature of 140°F and can go as high as 150°F. To minimize sediment buildup and improve energy efficiency, use your thermostat to adjust the water temperature if your unit’s settings are higher than 120°F.

3. Check the Anode Rod

The anode rod is a long, metal component inside your water heater that attracts minerals, keeping any corrosion contained to the rod before it can damage the rest of the tank. Therefore, your tank becomes vulnerable to corrosion when the rod wears down, eventually leading to rust-colored water, odors, and leaks. To check the anode rod, first turn off the unit’s power and water supplies. Open a faucet somewhere in your house to relieve pressure and drain some water out of the tank. Then, locate the insulation cap near the top of your tank, unthread it, and pull it out to check the condition of the anode rod.

Bonus: Schedule a Maintenance Appointment

By scheduling a maintenance appointment, a trained professional will be able to take a detailed look at your water heater and alert you to potential issues. They may also be able to flush the tank, install a new anode rod, and perform other necessary tasks to keep your unit functioning optimally.
