Steps to Replace a Water Heater Gas Valve Igniter Without Draining the Tank
Step 1: Turn off the Gas and Power Supply
Before you start working on the water heater, you need to turn off the gas and power supply. Turn off the gas supply at the shut-off valve and turn off the power supply at the circuit breaker.
Step 2: Remove the Burner Assembly
Next, you need to remove the burner assembly from the water heater. This is usually located at the bottom of the tank and is held in place by screws or clips. Use a screwdriver or adjustable wrench to remove any screws or clips and carefully lift the burner assembly out of the water heater.
Step 3: Remove the Gas Valve
The gas valve is located at the bottom of the water heater and is connected to the gas line. Use a pipe wrench to disconnect the gas valve from the gas line. Make sure to use two wrenches, one to hold the gas line and one to turn the gas valve. This will prevent damage to the gas line.
Step 4: Remove the Igniter
The igniter is connected to the gas valve and is held in place by screws or clips. Use a screwdriver or adjustable wrench to remove any screws or clips and carefully lift the igniter out of the gas valve.

Step 6: Reinstall the Gas Valve
Once the new igniter is installed, you need to reinstall the gas valve. Apply Teflon tape to the threads on the gas valve to ensure a tight seal. Use a pipe wrench to reconnect the gas valve to the gas line. Make sure to use two wrenches, one to hold the gas line and one to turn the gas valve. This will prevent damage to the gas line.
