Water Heater Safety Tips

Make sure to always keep the area around the water heater clear. Never store any kind of combustible items on or around the water heater. Last but not least, never use the top of the water heater for storage. 

These safety tips are to ensure that you do not leave anything dangerous around the water heater. Additionally, these steps ensure that the water heater has room to ventilate. If the water heater does not have the proper space for ventilation, then it will not run correctly. 

Tankless Water Heater

Tankless water heaters can be more efficient when it comes to having a water heater. Not only do they save space in your home, but they also have a longer lifespan than most water heaters with a tank. However, a tankless water heater may take some getting used to after having a regular water heater. 

If the water heater you are using does not have a tank, then a slight smell of gas may be normal. It is expected for a tankless water heater to smell like gas when it first cuts on. However, it is not normal for the water heater to smell while it is running. 

Fixing a Gas Leak

It is essential for you to address this situation as soon as possible, as gas leaks can be dangerous to your family. When replacing the old gas line, use a new gas line with protective polymer on it. This will ensure that you get more use out of the pipe. 

A regular gas line will only cost you about $15 to $25. A gas line with protective polymer will cost a little more. It will range anywhere from $30 to $40, but the quality will be worth the money. You will not need any extra tools. The only thing you will need to complete the job is a new gas line. The job itself is relatively simple, and you can complete it in seven easy steps. 

However, you must keep in mind that fixing the gas line may not solve the problem. You may need to call in a professional for help if it does not. Having somewhere to go for the night may also be necessary if you cannot fix the gas leak right away. 

Step 1: Clear a Path

When fixing a gas leak, it is clear that you will need to access the water heater. Make sure that you have a clear path to the gas pipe and the valve. It wouldn’t do any good to get there and have no room to do the job. 

It would also be a good idea to keep the space around the water heater cleared out. This will leave room for ventilation and prevent further issues. Cleaning around the water heater every few weeks can also keep dust from building up in unnecessary places. 

Step 2: Locate the Gas Pipe

You can find the pipeline above, behind, or to the side of the water heater. Make sure to locate the pipeline before you begin working. If you are unsure of the gas pipe’s location, a quick Google search will do the trick. 

Step 3: Turn off the Gas

Forgetting to turn the gas pipe off could result in physical harm to you and your family. You need to prevent this at all costs. Once you locate the pipeline, twist the handle counterclockwise until it stops. You will know that it is off when the handle is perpendicular to the path of the pipe. Do not continue trying to turn the handle after it stops, or it will break. 

Step 4: Remove the Flexible Gas Line

Removing the old gas line should be fairly straightforward. You will have to pop the gas line out of place and set it to the side. Remember to keep the old gas line out of your working space.  Also, do not touch your face while the smell is on your hands, for your own safety. 

Step 5: Replace the Gas Line

Replace the old line with the new line. The new line should feature the protective polymer to ensure a more extended time period before leaking. The new gas line should terminate no further than two feet off the ground and no less than 6 inches. These measurements will keep things at a comfortable distance for the water heater to run correctly. 

Step 6: Open All the Windows and Doors

Take a moment to open all of the windows and doors in your home. This creates escape routes for the remaining gas in the home. 

If you skip this step, you may not realize that the smell isn’t going away until it is too late. If the smell never goes away, there is no way to tell if the gas leak has stopped when you turn the gas back on. 

Step 7: Restore Power

Before turning the power back on, wipe down the water heater while it is cool. This will prevent sediment build-up from happening in the near future. Sediment build-up may cause a hissing sound when you are using hot water. 

Step 8: Check for a Gas Smell

Now that you have replaced the pipe and emptied the house of gas make sure that you can’t smell gas. If you continue to smell gas, this is a larger problem, and you need to call professionals. Turn the gas off, and immediately call the gas company. 

However, you can also buy a gas leak detector to notify you when the leak begins. You can find a gas leak detector at any Walmart close to you or on Amazon. They typically range anywhere from $20 to $25. Do not forget to leave a clear path around the water heater to ensure that there is room for ventilation. Leaving room for ventilation may also prevent condensation from touching hot surfaces.

Would it be safer to call a professional for a gas leak?

When it comes to a gas leak, you can never be too prepared. Gas leaks are highly dangerous and can lead to death. Therefore, it would be much safer to call a professional. Professionals are more aware of the severity of the situation. They also have the proper equipment to wear and use when it comes to fixing a gas leak. 

If you do not address the issue in a timely manner, you may be putting your neighbors at risk as well. Leaving the issue for an extended period of time could result in the loss of your home, or even worse, your life. This can also leave your neighbors at risk of losing their homes or lives as well. 

It is in your best interest to go ahead and call in the professionals and get yourself to safety. You should also give your neighbors a heads up too. This way they can be aware of the situation and do what they need to do to keep their families and homes safe.
