How to Replace a Water Heater
Gather Your Tools and Materials
Before you begin the installation process, you’ll need to gather all the necessary tools and materials. Here’s a list of what you’ll need:
- Adjustable wrench
- Teflon tape
- Pipe cutter
- Jigsaw
- Power drill
- Screwdrivers
- Pipe wrench
- Measuring tape
- New water heater
- New water heater pan
- New hot and cold water supply lines
- New gas line (if replacing a gas unit)
- New vent pipe (if replacing a gas unit)
Turn Off the Power and Water
Before you begin removing your old water heater, make sure to turn off the power and water supply. For electric units, turn off the circuit breaker. For gas units, turn off the gas supply and pilot light. You should also shut off the cold water supply valve.
Drain the Tank
Once the power and water supply are off, you can drain the tank. Connect a hose to the drain valve at the bottom of the tank and run it to a nearby drain or outside. Open the drain valve and let the tank drain completely.
Disconnect the Old Water Heater
Next, you’ll need to disconnect the old water heater. Use the pipe cutter to cut the hot and cold water supply lines and the gas line (if applicable). Disconnect any vent pipes and remove any mounting brackets or straps holding the unit in place.
Prepare the Area
Before installing your new water heater, you’ll need to prepare the area. Make sure the space is clean and clear of debris. If you’re installing a gas unit, double-check that the new vent pipe is the correct size and properly aligned.
Install the New Water Heater
Once the area is prepared, it’s time to install the new water heater. Use the measuring tape to ensure the unit is level and in the right position. Connect the hot and cold water supply lines and the gas line (if applicable). Attach any vent pipes and secure the unit in place with mounting brackets or straps.
Fill and Test the Tank
After the new water heater is installed, you can fill the tank with water and turn the power and water supply back on. For gas units, relight the pilot light. Check for leaks and make sure the unit is functioning properly.
