How to Drain a Water Heater
Draining a water heater is a relatively simple task that can be completed in a few hours. However, it is important to follow the steps carefully to avoid any damage to the water heater or your home.
Materials you will need:
- Bucket or drain hose
- Adjustable wrench

Step 1: Turn off the water supply to the water heater.
The water supply to the water heater is usually located near the top of the unit. There will be two valves, one for the hot water and one for the cold water. Turn both valves off by turning them clockwise.
Step 2: Turn off the power to the water heater.
If your water heater is electric, turn off the power at the circuit breaker panel. If your water heater is gas, turn off the gas supply at the gas valve.
Step 3: Open the drain valve.
The drain valve is usually located near the bottom of the water heater. Place a bucket or drain hose under the valve and open it by turning it counterclockwise.
Step 4: Wait for the water to drain.
It will take some time for the water to drain from the water heater. The amount of time it takes will depend on the size of the water heater and how much water is in it.
Step 5: Close the drain valve.
Once the water has stopped draining, close the drain valve by turning it clockwise.
Step 6: Turn on the water supply to the water heater.
Turn on the water supply to the water heater by turning both valves counterclockwise.
Step 7: Turn on the power to the water heater.
If your water heater is electric, turn on the power at the circuit breaker panel. If your water heater is gas, turn on the gas supply at the gas valve.
Step 8: Check for leaks.
Once the water heater is turned back on, check for leaks around the drain valve and any other connections. If you find any leaks, tighten the connections or call a plumber.
FAQ
