How Do You Drain a Hot Water Heater?
Now that you understand why draining your hot water heater is essential let’s get into the nitty-gritty of how to do it. Before we get started, here’s a list of everything you’ll need:
- A garden hose
- A bucket
- A pair of pliers
Step 1: Turn off the Power or Gas Supply to the Heater
Before you start draining the hot water heater, turn off the power supply or gas supply. If your heater is electric, turn off the power at the breaker box. If it’s gas, turn off the gas supply valve.
Step 2: Turn off the Cold Water Supply
Locate the cold water supply valve and turn it off. This valve is typically located above the heater or near it.
Step 3: Open the Pressure Relief Valve
Next, you’ll need to open the pressure relief valve. This valve is typically located near the top of the heater and allows air into the tank as the water drains out. Place a bucket beneath the valve to catch any water that comes out.
Step 4: Connect the Hose
Attach one end of the garden hose to the drain valve at the bottom of the heater. The other end should be outside or in a drain. Ensure that the hose is securely attached.
Step 5: Drain the Tank
Open the drain valve and let the water flow out through the hose. Once the water has stopped flowing, close the valve and let the remaining water drain out of the pressure relief valve. You may need to repeat this step a few times until the water runs clear.
Step 6: Close the Valves
Once all the water has drained out of the tank, close the drain valve and the pressure relief valve. Remove the hose from the drain valve.
Step 7: Refill the Tank
Open the cold water supply valve and allow the tank to refill. Once the tank is full, turn on the power or gas supply to the heater.
