Safety Precautions

You should take several safety precautions when replacing your residential water heater.

First, make sure to turn off the power supply to the water heater at the circuit breaker. This will prevent any electrical accidents while you're working on the unit.

Next, shut off the water supply and drain the tank to avoid any water leakage during the replacement process.

It's also important to wear protective gear, such as gloves and safety goggles, to protect yourself from potential hazards.

Additionally, be cautious of the hot water that may still be in the tank and use a bucket or hose to safely drain it.

Lastly, if you're unsure or uncomfortable with the replacement process, it's always recommended to hire a professional to avoid any potential mishaps.

Gathering Necessary Tools

To gather the necessary tools for replacing your residential water heater, begin by ensuring you have the following items on hand.

  • A pipe wrench or adjustable wrench to disconnect the water supply and gas lines. These tools will help you loosen and tighten the fittings securely.
  • A screwdriver to remove any screws or fasteners holding the old water heater in place.
  • A bucket or large container ready to catch any water that may drain from the old unit.
  • A tape measure to ensure the new water heater fits properly in the available space.
  • A pair of gloves and safety glasses to protect yourself during the replacement process.

With these tools at your disposal, you'll be all set to successfully replace your residential water heater.

Turning off the Water Supply

To begin the process of turning off the water supply for your residential water heater replacement, start by locating the shut-off valve. It's typically located near the water heater or in the basement. Once you have located the valve, turn it clockwise to shut off the water supply. It's important to ensure that the valve is fully closed to prevent any water from flowing into the water heater during the replacement process.

After turning off the water supply, open a faucet in your home to relieve any pressure in the pipes. This will help prevent any water from spilling out when you disconnect the water heater. Remember to keep the faucet open until the replacement is complete and the water supply is turned back on.

Draining the Old Water Heater

After turning off the water supply and relieving any pressure in the pipes, proceed to drain the old water heater.

To do this, locate the drain valve at the bottom of the heater. Attach a garden hose to the valve and place the other end in a suitable drainage area, such as a floor drain or outside. Make sure the hose is securely attached to prevent any leaks.

Once everything is in place, open the drain valve by turning it counterclockwise. Allow the water to flow out of the heater until it stops completely. This may take some time, so be patient.

Once the tank is empty, close the drain valve and remove the hose.

You have successfully drained the old water heater in preparation for replacement.

Installing the New Water Heater

Once you have drained the old water heater, you can now proceed to install the new water heater.

Start by carefully positioning the new water heater in the designated area. Make sure it's level and aligned properly with the existing plumbing connections.

Connect the cold water inlet and the hot water outlet pipes to the corresponding valves on the new water heater. Use pipe tape or joint compound to ensure a tight seal.

Next, attach the pressure relief valve and the temperature and pressure relief valve pipe.

Connect the gas supply line to the gas control valve, or if you have an electric water heater, connect the electrical supply.


In conclusion, replacing a residential water heater can be a DIY project if you follow the necessary safety precautions and have the right tools.

Remember to turn off the water supply and drain the old water heater before installing the new one.

By taking these simple steps, you can successfully replace your water heater and ensure a steady supply of hot water in your home.
