Introduction
Every homeowner wants their water heater to last as long as possible, but many forget that these systems need regular maintenance to perform efficiently. Over time, minerals in your water—especially if you have hard water—settle at the bottom of the tank, creating a layer of sediment that can cause your heater to work harder, make noise, and eventually fail.
Flushing your water heater removes this buildup, restores efficiency, and helps prevent costly repairs. The question is: should you do it yourself or call a professional? Let’s look at what’s involved, the risks, and when to contact Trade Pro Plumbing for expert help.
Why Flushing Your Water Heater Matters
Whether you have a gas or electric water heater, sediment buildup is inevitable. As water heats, minerals like calcium and magnesium fall out of suspension and collect at the bottom of the tank.
Without regular flushing, this sediment causes several problems:
- Reduced efficiency: The heating element or burner must work harder to heat the water.
- Less hot water: Sediment takes up space inside the tank, reducing capacity.
- Strange noises: You may hear rumbling or popping as sediment moves and traps air.
- Shortened lifespan: Excess heat under sediment can damage the tank lining and cause leaks.
Flushing once or twice a year keeps the tank clean, helps your heater run efficiently, and extends its life.
How to Flush a Water Heater Yourself
If you’re comfortable working with basic plumbing tasks, you can flush your water heater at home. Here’s a step-by-step breakdown of the process:
- Turn Off the Power or Gas Supply
- For electric water heaters: Switch off the circuit breaker.
- For gas water heaters: Turn the gas control knob to “Pilot.”
This prevents the heating element from turning on while the tank is empty, which could cause serious damage.
- Shut Off the Cold Water Supply
Locate the cold water valve on top of the tank and turn it clockwise to stop water from entering the heater during flushing.
- Connect a Hose to the Drain Valve
Attach a garden hose to the drain valve near the bottom of the tank and run the other end to a floor drain or outside area. Make sure the hose is secure to avoid leaks.
- Open a Hot Water Faucet
Open one hot water tap inside your home. This helps air enter the system and allows water to drain more smoothly.
- Drain the Tank
Open the drain valve and let the water flow until the tank is empty. Be cautious—this water will be very hot.
- Flush with Fresh Water
Once the tank is drained, turn on the cold water supply for a few minutes to flush out any remaining sediment. Keep flushing until the water runs clear.
- Close the Drain Valve and Refill the Tank
Shut off the drain valve, remove the hose, and turn the cold water supply back on. Leave the faucet open until water runs steadily from it—this means the tank is full again.
- Restore Power or Gas
Turn the breaker or gas supply back on, and your heater will start reheating water.
The Risks of Flushing a Water Heater Yourself
While flushing may sound simple, mistakes can cause damage or safety hazards. Here are common DIY risks:
- Scalding from hot water: The water inside the tank can reach temperatures over 120°F.
- Damaging the drain valve: Over-tightening or forcing the valve can cause leaks.
- Incomplete flushing: Without proper equipment, sediment often remains inside.
- Electrical hazards: Forgetting to turn off power before draining can damage heating elements.
- Gas leaks: Mishandling gas valves can create dangerous conditions.
Professional plumbers like those at Trade Pro Plumbing use specialized equipment to ensure your tank is fully cleaned and tested for safety.
When You Should Call a Plumber Instead
While DIY flushing works for some homeowners, it’s best to call a professional if:
- You haven’t flushed your water heater in over two years.
- You’re not comfortable working around gas or electricity.
- The tank is over 8 years old.
- You hear loud banging or popping noises from the tank.
- There’s rust or water leaking around the base.
A plumber can inspect your system, identify early signs of wear, and recommend whether flushing or replacement is the better option.

How Hard Water Impacts Your Water Heater
Homes in Northwest Arkansas often deal with hard water, which accelerates mineral buildup inside the tank. Even with annual flushing, heavy sediment can accumulate faster than expected. Installing a water softener can help reduce mineral deposits, improve efficiency, and extend the lifespan of your plumbing system.
