How to Turn Off a Gas Water Heater

For gas water heaters, it's crucial to prioritize safety and professional service. Here’s a general outline of the steps involved, but we recommend contacting a professional plumber for assistance:

1. Adjust the Temperature Dial: Turn the temperature dial to the "off position."
2. Turn Off the Gas Supply Valve: Locate the gas supply valve on the gas supply line. Rotate the valve handle until it is sticking straight across the pipe, cutting off the gas flow.
3. Shut Off the Main Gas Supply: For added safety, consider turning off your home’s main gas supply. However, this should be done by a professional to ensure safety.
4. Deactivate the Water Supply Valve: Shut off the water valve on the cold water supply line leading to the heater.
5. Check for Safety: If you suspect a gas leak, it's imperative to contact a professional plumber immediately for help. Our team is equipped to handle such emergencies safely and efficiently.

How to Shut Down an Electric Water Heater

For electric water heaters, it's essential to prioritize safety and professional assistance. While these steps provide a general idea, we highly recommend contacting a professional plumber to ensure a safe and thorough shutdown:

2. Turn Off the Circuit Breaker: Switch off the breaker labeled for your electric hot water heater to cut electricity. Our expert team can assist with this process to guarantee your safety.
3. Deactivate Additional Controls: Some electric water heaters have a control panel or a power switch on the unit itself. Allow our professionals to handle these components for added safety.
4. Turn Off the Water Supply: Our skilled technicians will shut off the water supply valve to stop the flow of water into the tank, ensuring a complete and secure deactivation.

Draining your water heater can enhance its performance and remove sediment buildup. While these steps give you an idea of the process, we strongly recommend relying on our professional service to ensure safety and efficiency:

1. Power Down the Heater: Our skilled technicians will ensure the heater is completely off and allow the water to cool safely.
2. Attach a Garden Hose to the Drain Valve: We will connect one end of the hose to the drain faucet at the bottom of the tank and the other end to a lower location, such as an outdoor space or floor drain, ensuring proper drainage.
3. Open a Hot Water Faucet: Our experts will open a hot water faucet to allow air into the system, preventing vacuum formation and ensuring smooth draining.
4. Drain the Tank: Our team will open the drain valve and let the water flow out until the tank is empty, handling the entire process with care and expertise.
