Step-by-Step Guide to Removing the Gas Valve

Now, let’s get into the nitty-gritty of removing your water heater gas valve. Follow these steps carefully:
1. Disconnect the Gas Line:

• Turn off the gas valve: Locate the valve handle and turn it to the “off” position.

Time for a New Gas Valve?

If you’re replacing the gas valve, make sure you choose a compatible model. Consider the following factors:

• Type of gas: Ensure the valve is compatible with the type of gas used in your home (natural gas or propane).
• Valve size: Match the size of the new valve to the existing gas line connection.
