Can You Leave Propane Tank Attached To Grill?

First of all, let us provide you with a direct answer to this question. If you are storing the grill outside of your house, you can keep the tank connected to the grill. Still, it is important not to leave the valve of the propane tank open when you store it. For those who intend to keep their grill inside, do not keep the gas tank and machine connected, no matter what.

Although that is a rule of thumb, we are not 100% recommend doing so. Instead, we would suggest you disconnect and store the gas tank machine when you are not using them. Another thing that you should stay away from is storing your grill inside your house. Keeping a propane gas tank indoors is always a dangerous thing and can put you and your loved ones in an undue risky position.

When dealing with powerful fuel resources such as gas, be it propane or from your direct line, it is mandatory to focus on safety rather than convenience. Still, if you prefer keeping the gas tank attached to the grill for whatever reason, make sure you shut down the valve on the propane tank without fail.

If you happen to forget and only turn off the knobs on the grill, the gas will flow through the line and cause catastrophic accidents. Moreover, it will lead you to waste gas, which is something you don’t want to take place, especially during the winter.

Also, keeping the gas tank connected to the grill when you are not using it will lead to something called “bypass. When this happens, the gas flow from the tank to the machine will be reduced, which will make it difficult for the grill to preheat as it would do in normal circumstances. Usually when in “bypass” the temperature will not be able to exceed 300°.

All in all, the best option we recommend is to disconnect the propane gas tank from the grill while it is not in use. And, yes, the readers who continuously asked us, “can you leave propane tank connected to grill” now should have the correct answer with them.

Do You Leave The Gas On When Grilling?

This is pretty much a straightforward thing, but we know that some think otherwise and tend to switch off and on when cooking. Instead, you can control the flames and heat using the knobs on the machine rather than doing so from the gas tank itself.

In an ideal world, you should be touching the propane gas tank only two times when you are cooking, when starting and finishing. Also, keep it in a place where you and your invitees don’t have a chance to come across during the BBQ session.


So, can you leave a propane tank on? When cooking, yes, absolutely, but when not, you should shut down the gas supply from the tank to the machine without fail. Safety is the number one reason for doing so. Also, it leads to gas wastage and improper cooking temperature. So, leave no chance to the propane tank valve left open when it is not in operation.
