You probably take hot showers for granted, but your water heater needs regular care to run efficiently and last longer. A big part of that care is knowing how to flush a water heater. It’s easier than you think once you understand the basics, so in this guide, our team from Jackson Plumbing, Heating & Air Conditioning walks you through the steps.
Why Do Water Heaters Need To Be Flushed?
Water heaters work day and night to keep hot water ready when you need it. Over time, minerals from your water supply settle at the bottom of the tank. This sediment buildup causes the burner or heating element to work harder than necessary. If you ignore it, your water heater could wear out prematurely.
Flushing your water heater drains out sediment, removing this insulating layer from the bottom of the tank so it runs more efficiently. This aspect of water heater maintenance helps lower your utility bills and reduces the risk of unexpected breakdowns.
The general recommendation is to flush your water heater once a year. However, because water in the Decatur area has a higher mineral content, more frequent flushing may help prevent heavy sediment buildup.
Step-By-Step Water Heater Flushing Guide
If you decide to attempt flushing your water heater yourself, make sure you have a hose and a safe place to drain the hot water before you begin. Then, follow these flush water heater steps:
- Shut off the power and water supply: If you have an electric water heater, turn off the power at your breaker panel. For gas models, set the dial to the pilot setting. You’ll also need to shut off the cold water supply to the tank.
- Connect a hose to the drain valve: Look for a drain valve at the bottom of your heater. Attach a garden hose and run it to a safe drainage spot, such as a floor drain or an outside location. Be ready for hot water to start flowing.
- Open the drain valve: Wearing gloves to protect your hands from scalding water, open the drain valve. As the tank empties, look for dirty water flowing from the hose. That’s evidence of the sediment you’re removing.
- Flush with water: Once the tank is mostly empty, briefly turn the cold water supply back on with the drain valve open. This rinses out even more sediment. Repeat as needed until the water from the hose runs clear.
- Close the valve and refill: Close the drain valve, remove the hose, and turn the cold water supply back on. Let the tank refill, and then restore power or switch your gas burner back to the normal setting.
When To Call a Professional Plumber
Some water heater jobs are perfect for DIY enthusiasts, but others are best left to the experts. Is your tank leaking, making loud noises, or visibly corroded? Has your water heater not been serviced in several years? Are you dealing with sediment that just won’t clear?
If you answered yes to any of these questions, stop and call a plumber. Even if you simply feel unsure of what you’re doing, it’s worth turning the job over to a professional.
A licensed plumber has the tools and training to handle tough jobs safely and efficiently. They can also find and repair hidden issues that a simple flush won’t fix. You’ll save time and enjoy peace of mind, knowing the job is done right.
