Diagnosis
If your water heater is making unusual sounds or you're seeing bits of debris in your hot water, it's likely due to a buildup of minerals and sediment at the bottom of the tank. This accumulation not only makes your heater work harder, reducing its energy efficiency and potentially damaging the tank, but it can also shorten the appliance's overall life.
Tools Needed
- Garden hose
- Adjustable wrench
- Bucket
- Towel or rags
- Work gloves
- Safety glasses
Warnings
- Always turn off the power or gas supply to the water heater before starting to avoid electric shock or gas leaks.
- The water inside the tank can be very hot. Wear gloves and safety glasses to protect yourself from burns and splashes.
- Ensure the drain valve can handle the pressure and temperature; if it appears damaged, do not proceed and call a professional.
Step-by-Step Instructions
- First, ensure the water heater is safe to work on by turning off its power source (electricity or gas).
- Locate and shut off the cold water supply valve leading into the water heater.
- Attach a standard garden hose to the drain valve situated at the very bottom of the tank.
- To allow air into the tank, open any hot water faucet in your home.
- Position the free end of the garden hose where you want the drained water to go, such as a floor drain or outside.
- Use an adjustable wrench to open the water heater's drain valve.
- Be patient as the tank completely empties; this process can take anywhere from 30 minutes to an hour.
- With the tank now empty, briefly turn the cold water supply valve back on. This helps to agitate and flush out any lingering sediment.
- Close the drain valve securely.
- Remove the garden hose.
- Gradually open the cold water supply valve again to refill the tank.
- Once the tank is full and you see water flowing from the hot water faucet you opened earlier, you can safely turn the power or gas supply back on.
Troubleshooting
- If the drain valve is stuck, try gently tapping it with a wrench. If it still won't budge, you may need to replace the valve.
- If sediment continues to come out after flushing, try draining and refilling the tank a second time.
- If you hear unusual noises after refilling, double-check that the tank is completely full and all air has been purged.
Preventive Tips
- Flush your water heater at least once a year, or more often if you have hard water.
- Consider installing a water softener if you have very hard water.
- Periodically check and replace the anode rod, which helps prevent tank corrosion.
