Production Training - Detaching Water Heaters

Safety First!

• Turn Off the Power: For electric water heaters, turn off the main power supply to the unit at the breaker box. 

  • Confirm the power is off with a voltage tester.

• Turn Off the Gas: For gas water heaters, turn off the gas supply valve at the appliance.

• Allow for Cooling: Allow the water heater to cool down completely before proceeding. 

  • This can be skipped if using a garden hose that is rated for hot water.

• Turn Off The Water to the Property: Confirm the water is off before proceeding.

Draining the Water Heater: (ensure there is no power to the water heater as draining a water heater with the elements still energized can create a dangerous situation)

1. Attach a Garden Hose: Connect a garden hose to the drain valve located at the bottom of the tank.

2. Open the Drain Valve: Open the drain valve slowly to release the water.

   • If water doesn't drain from the water heater, turn the water onto the property again.

   • If water will not flow from the hose, open and close the valve a few times.

   • If water will still not flow, close the valve & contact management, as a plumber is required to detach due to sediment blocking the drain.

3. Open a Hot Water Faucet: Open a hot water faucet located on the highest level of the house to allow air to enter the tank and facilitate drainage.

Disconnecting the Water Heater

• Turn Off the Water Supply: Turn off the cold water supply valve to the water heater.

• Disconnect the Water Lines: Disconnect the cold water supply line and the hot water outlet line from the water heater. This will likely require cutting the lines with a copper cutting tool, or a reciprocating saw. Place a bucket or pan underneath to catch any remaining water. Cap the lines 

  • Cap the water lines upon completion of the disconnect.

• Disconnect the Gas Line (for Gas Water Heaters): If applicable, disconnect the gas line from the water heater. Have a cap for the gas line handy to cap the gas line after disconnecting from the water heater. 

• Disconnect the Electrical Connections (for Electric Water Heaters): Open the lid on the top of the water heater, remove the wires & disconnect the electrical connections from the water heater. Pull the wire leading to the water heater out of the grommet. Reinstall the wire nuts to the wires from the panel. Tuck them out of the way.

Moving the Water Heater

1. Prepare for Moving: If possible, tilt the water heater slightly to drain any remaining water.

   • Contamination in the bottom of the water heater may make draining the water heater exceptionally slow.. 

2. Use Proper Lifting Techniques: Use a dolly or hand truck to move the water heater. Avoid lifting heavy objects alone.

3. Protect the Floor: Use moving blankets or cardboard to protect the floor from scratches.

4. Position the water heater: Place the water heater in a location that's not in the way of production work. 

Disposal (if necessary)

• Local Regulations: Check with your local waste management authority for proper disposal guidelines. Some areas may have specific regulations for disposing of old water heaters.

• Recycling: In some cases, you may be able to recycle the old water heater. Contact your local recycling center for more information.

Important Notes:

• Professional Installation: Always hire a qualified plumber for professional installation of a water heater.

• Safety Precautions: Wear appropriate safety gear, such as gloves and safety glasses, when working around water heaters.
