Essential Steps for Gas Water Heater Installation
Ready to get started? Here’s a step-by-step guide to walk you through the process:
1. Safety First: Preparation is Key
- Turn off the Gas: Locate the gas shut-off valve for your existing water heater and turn it to the “off” position.
- Cut the Water Supply: Shut off the water supply to your current water heater.
- Drain the Tank: Connect a garden hose to the drain valve at the bottom of the tank and run it to a safe drainage area. Open the valve to drain the tank completely.
- Disconnect the Gas Line: Loosen the gas line connection using a wrench. Important: Double-check for the smell of gas and ensure the area is well-ventilated.
- Disconnect the Water Lines: Carefully disconnect the hot and cold water lines leading to your old water heater.
2. Out with the Old: Removing the Existing Water Heater
- Vent Pipe Removal: If your old unit has a vent pipe, carefully disconnect it.

- Installing the Temperature and Pressure Relief Valve: This valve is crucial for safety. Install it according to the manufacturer’s instructions.
4. The Moment of Truth: Testing & Final Checks
- Check for Leaks: Turn the gas supply back on and use a soap and water solution to check for leaks around all gas connections.
- Fill the Tank: Open the cold water supply valve to fill the tank.
