By flushing the tank regularly, you can remove these deposits and extend the life of your water heater.
Materials You’ll Need
- Garden hose
- Bucket or drain pan
- Adjustable wrench
- Rag or towel
Safety Precautions
Before you begin, it’s important to take safety precautions:
- Turn off the water supply to the water heater.
- Allow the water in the tank to cool down for several hours.
- Wear gloves and safety glasses to protect yourself from hot water and debris.
Step-by-Step Flushing Instructions
1. Connect the Hose
Attach the garden hose to the drain valve at the bottom of the water heater. Open the valve to allow water to drain into the bucket or drain pan.
2. Open the Pressure Relief Valve
Locate the pressure relief valve on the top of the water heater. Open the valve by lifting the lever or turning the handle counterclockwise. This will release any remaining pressure in the tank.
3. Flush the Tank
Let the water drain out of the tank until it runs clear. This may take several minutes. As the water drains, sediment and debris will be flushed out.
4. Close the Drain Valve
Once the water runs clear, close the drain valve at the bottom of the water heater.
5. Close the Pressure Relief Valve
Close the pressure relief valve by pushing the lever down or turning the handle clockwise.
6. Reopen the Water Supply
Turn on the water supply to the water heater. Allow the tank to fill up.
7. Check for Leaks
Once the tank is full, check for any leaks at the drain valve or pressure relief valve. Tighten any loose connections if necessary.
Regular Flushing Schedule
The frequency of flushing your water heater tank depends on the hardness of your water. For areas with hard water, flushing the tank every 6-12 months is recommended. For areas with soft water, flushing the tank every 1-2 years is sufficient.
