As we wind down another summer season, grilling season is still in full bloom. Gas grills are center stage dishing out burgers, dogs, and smiles. But all grillers know one thing can bring the fun to a halt: running out of propane!

Many homeowners ask us, “Can I hook up my grill to my home propane tank? It always has plenty of gas.”

While it sounds like a reasonable idea, you shouldn’t hook your gas grill to your home propane tank. The practice is neither safe or efficicient for home grilling.

 

The Easy “How-To” Guides Are Misleading

Search online and you will come across numerous “how-to” guides on making the connection between grill and tank. Readers will become privy to glowing recommendations that share how convenient and practical it is to hook your grill and tank together. Unfortunately, there is much more to this story than these recommendations lead on.

What they fail to mention that hooking your home supply to your grill practice will cause more headaches for you in the future.

Drawbacks of Hooking Up Home Propane Tank to Grill

It will cost $150-$300 to professionally hook up

This is not a Do-It-Yourself job. So if you decide to hook your tank up to the grill, expect your pockets to feel the heat. Your propane supplier will charge $150 or more to perform the hook up.

Gas leaks burn major propane

If you connect your 250 gallon+ home tank to your grill, accidentally leaving your grill’s propane supply on will risk a ton more propane than a 20lb grill tank! Remember, your tank is only filled to 80% total capacity. For example, if you accidentally leave your full 20lb grill tank, you are risking a maximum of 4.7 gallons – then it runs out. But if it’s hooked up to your home tank, you are risking 250-500 gallons – or $450+ dollars worth of propane.

Even if you are diligent about turning the gas off, gas leaks still can happen. It’s not uncommon for unwelcomed guests like mice, rats or squirrels to chew on a propane tank line and cause a leak. The exposed propane line from your tank to your grill could open you up to propane leaks you don’t even realize!

You are compromising your safety

The grill tank in your backyard contains an automatic shut-off valve for safety to protect against combustion. However, if you decide to connect your grill to your home tank, the shut-off valve is eliminated.

Limited portability of your grill

When colder temperatures become more frequent, your grilling days are numbered. You might move the grill to a covered area or into the garage if you don’t want it exposed to the fall and winter elements. Attaching the grill to the home propane tank makes this more difficult. It would require you to unhook everything and safely seal propane lines. Spare yourself the trouble and transport your grill without any obstruction.

Overall, it is not worth connecting your home propane supply to your gas grill. If you are tired of running out of gas mid-cooking, then here are some tips.

How to avoid running out of propane gas for your grill

  • Keep an extra tank available – store an extra tank in a cool, dry place like your garage. Refill the spare tank to make sure you always have one on hand.
  • Weigh your grill tank – an empty 20lb tank will weigh 18-20 lbs. A full tank will weigh 38-40lbs.
  • Buy a propane gauge – you can buy a $15-$20 gauge at the hardware store to tell you how much propane you have left.
