Absolute Airflow provides professional water heater flush services at affordable prices, but how do you know when your water heater needs to be flushed? Periodic flushes are important to avoid premature breakdowns, hot water shortages, and noise. The process involves draining all the water from your water heater tank, along with the sediment that has accumulated. This sediment naturally accumulates from the minerals contained in hard water.

To avoid serious problems, be sure to flush your water heater at the recommended intervals.

How Often Should My Water Heater Be Flushed?

Hard water contains minerals that settle out and build up in the tank and pipes. How frequently your water heater should be flushed depends on where you live. The concentration of calcium carbonate in water has a lot to do with it. The Northeast, South, and Northwest regions of the United States tend to have less calcium carbonate, while portions of the Midwest and Rocky Mountains have more. In lower concentration regions, your water heater should be flushed once a year. Where mineral concentrations are higher, it should be flushed at least twice a year.

What Does the Process Entail?

You will need a professional to perform a water heater flush properly. They will first turn off the gas connection, cold water supply, and water heater thermostat before turning on a hot water tap and opening the pressure relief valve. The drain spigot will then be opened to flush the tank of water, sediment, and mineral buildup. In the process, water in the tank is emptied through a hose and exits through a drain.

When the flush is complete, the drain valve will be closed. The water heater tank can be filled once again. A technician will reopen the water supply valve and power up the heater. While the process may not sound complicated, don’t take a DIY approach to draining a water heater; it can be dangerous.

Why Flushing Your Water Heater Is Important

If sediment is left to build up in the tank, the water can become overheated. Water expands as it heats, creating pressure that can cause the tank to leak or even explode. Water heater failure is usually preceded by often expensive repairs caused by sediment causing key components, such as the heating element, to fail.

Sediment can also dramatically reduce the capacity of your water heater. Gallons of sediment can accumulate. If you have a 30-gallon water heater reduced by 10 gallons, the hot water available to your household can be significantly reduced.

In addition, water heaters with sediment buildup can be quite noisy. You might hear loud knocking sounds or popping noises if your tank is filling up. The noises are caused by overheated water and steam that causes sediment to move around within.
