Water heaters are typically install-and-forget systems, but they do require maintenance and regular flushing now and then. It might be a little tricky if it’s your first time doing it, so today’s post has a few pointers from Casper Plumbing & Heating to help you.
While purified and sanitized, municipal water supply still contains minerals such as calcium and magnesium, which can lead to sediment buildup in your water heater. This buildup not only affects the efficiency of your water heater but can also lead to higher utility bills and premature failure of the unit. Regular flushing helps remove these sediments, ensuring your water heater operates efficiently.
You might wonder how to tell when it’s time to flush your water heater. One noticeable sign is a reduction in the hot water supply, meaning your showers become shorter before the water turns cold. Another telltale sign is unusual noises, like popping or rumbling from the tank, indicating sediment buildup. If you’ve not flushed your water heater for several years, consider hiring a professional plumber from Casper Plumbing & Heating to avoid the risk of leaks and other complications.
Turn Off the Water Heater and Water Supply: Start by turning off the cold-water supply valve on your water heater. If it’s gas-powered, set the thermostat to “pilot.” For electric heaters, turn off the power at your home’s electrical panel.
Connect a Garden Hose to the Drain Valve: Attach one end of a garden hose to the drain valve at the bottom of the water heater and place the other end in a drain or outside.
Run Hot Water and Open the Drain Valve: Open a hot water tap nearest to the water heater to ease pressure and allow for faster draining. Then, open the drain valve, allowing the water to flow out.
Flush the Tank: With the drain valve open, turn the cold water supply on and off a few times until the water running out is clear of sediments. This helps remove any remaining deposits from the bottom of the tank.
Refill the Water Heater: Close the drain valve, remove the hose, and ensure the cold water supply valve is open. Wait for the tank to refill before turning the water heater back on. Check for leaks and ensure everything is running smoothly.
If you encounter slow draining or none at all, there could be significant sediment blocking the valve, or a vacuum may have formed inside the tank. In such cases, Casper Plumbing & Heating advises contacting a licensed plumber for assistance to avoid damaging your water heater.
Water heaters typically have a lifespan of 8 to 10 years, depending on the model and water conditions in your area. If your water heater is approaching this age or exhibiting signs of failure despite regular maintenance, it might be time to explore replacement options.
