If your home uses atankless gas water heater, you must understandhow to turn off a Gas water heater. Follow these simple ways to do it right.
Step 1: Turn Off the Water Heater Valve
Check the front of the tank, and you will notice a red or black button. Sometimes these buttons are hidden behind insulating materials, and you have to pull it off to reveal the button. Move or turn the switch from the “on” position to the “off” position.
Turning off the heater will stop the pilot from working and the burner from heating. Pull off the heat shield and check inside for signs of heat or flames. If you’re doing maintenance, turn on the pilot, and the flame stays lit, but the burner won’t work.
Step 2: Turn Off the Line that Supplies Gas
If you want to go out and hear the heater making a hissing sound, turn off the gas line valve. Just go and shut off the valve located on the gas line close to the heater. Turn the lever until it is perpendicular to the gas line.
If you can find any valve, trace the gas line until you find a handle that serves as the switch. Gas line valves are often easy to locate, and you don’t need to search for too long. But if you can’t find it, contact a local plumber.
Step 3: Shut Down the Water Heater
If you’re leaving home during winter, ensure you drain the water in the tank so that it doesn’t get frozen. Turn off the heater and wait for 12 hours to allow the water cool down and to avoid getting scalded. To drain your tank, make sure you:
Put a bucket under the pressure relief valve so that water goes directly into the bucket. Open the relief valve to allow steam to escape and then gently release the lever.Insert a hose to the drain valve located right at the bottom.
Pull the hose to the particular spot you want to drain the water. Normally the draining area should be on a higher elevation than the position of the water tank. If you have a garden, it may be a good time to drain the water into your garden.
Turn off the cold water valve and turn on the hot water faucets to let the water out.Keep the drain valve open until all the water runs out and then close it.
Next, turn off all the open faucets in the house. If the water doesn’t drain, it could be that mineral deposits have blocked the drainage channels. Shut off the valve and then pull off the hose to clear out all deposits. Reattach the hose and turn on the valve once again.
How to Turn Off an Electric Water Heater
The following five steps are useful in shutting down your electric water heater. Follow the guidelines and learnhow to turn off water heaterin your home.
Step 1: Turn Off the Breaker
The first thing abouthow to turn off water heater electricis to locate the two-pole breaker. It is about 30 or 50 amps and usually marked.
You should turn off the power at the breaker panel even if you have shut down the electric water heater. If the breaker has lock-out lugs, put them on the breaker.
If you feel you might get confused, label the breaker with paper tape to warn against mistakes. It is also a good idea to tell everyone in the house what you are up to at that moment. They should avoid going near the service panel or the water heater until you are through.
As a way of precaution, use a non-contact voltage tester to make sure there is no heat inside the cover. It is risky to expose yourself to shock or heat when replacing the water heater element.
Step 2: Put a Tag on the Breaker
Safety standards demand that you put a tag on what you are working on to avoid getting anybody hurt. When you are dealing with electricity, it is wise to lock the area off to keep off potential victims. Tag the place and the equipment to warn anyone who may mistakenly walk close to the spot.
In the home, shutting down the breaker isn’t enough as everyone is exposed to similar danger. It will serve well if you put some identification and restriction in place to warn family members of potential dangers. While you may not copy construction site protocols, you have to make sure everyone is safe.
Don’t take the idea of safety as a joke since single electrocution can take a life. Take practical steps to make sure you cut off power completely from the heater and the breaker.
Another way to maintain safety is to put paper tape on the breaker and mark it “Do Not Touch.” Anyone who reads the warning will stay away from the danger.
Step 3: Cool Off the Water
You will need to cool off the water in the tank before you make any repairs. It is good to turn off the heater to stop the water from further heat. Allow the water to naturally and gradually cool off on its own.

Once the repair is done, turn on the heater and allow the water to heat up normally. Give an hour before using hot water for shower, laundry, or dishwashing anywhere in the home.
Step 4: Turning Water Off
Water tanks should always have a shut-off valve on the outlet outside the home. The location of the tank prevents it from building excessive internal pressure. Turn off your cold water supply when working on the hot water tank.
If your tank has two valves, find the one which brings in cold water and turn it off. It is usually the valve on your right when you stand facing the tank. Normally, two valves shouldn’t be found on a supply line, so be careful while doing it.
If water is running through the pipes, feel them with your hands. The cold line is for cold water while the hot pipe is for hot water.
You can decide to turn on a water faucet in the house. The one that vibrates as water rushes out is the hot water supply line. Put a label on the cold line to remind yourself which valve should remain locked.
Step 5: Drain the Hot Water Tank
As you begin to understandhow to turn off hot water heater supply, you’ll discover a few facts. You can carry out some activities without draining the water tank. If you are adjusting or testing the thermostat or checking the power supply unit, you may leave the tank full.
Activities like removing or changing the element or flushing sediments require you drain the water first. The buildup of deposits can affect the heating of water in the lower part of the tank. Turn off the heater and allow the water to cool down before draining and repairs.
