How to Connect a Gas Grill to a House Propane Line?

A propane gas grill is a great way to cook outdoors, and more and more people are looking for ways to convert their traditional charcoal grills into propane. One of the most popular methods is connecting it directly to your house’s natural gas line. This article will teach you how to do this as well as give you some safety tips about working with any type of gas grill. 

What You’ll Need:

– Propane Gas Grill (obviously)

– Hose adaptor to connect gas grill regulator to house pipe adaptor (some states use a third type of connector, this is explained below)

– Access to your house’s natural gas line and access to the outdoor propane line for your grill

– Propane tank (if you’re not connecting to your house’s gas supply)

Steps of Connecting to a Gas Grill to a House Propane Line:

Step 1 – Turn Off The Gas Line to Your House:

Be sure to turn the main gas line that is attached to your house off. This is usually located outside in your front yard by your water meter. If you aren’t comfortable turning it off yourself, contact a plumber or do it for you.

Step 2 – Turn Off The Regulator Valve on Your Propane Tank:

Be sure you already have a propane tank attached to the grill and it is turned on. Turn off your propane tank regulator valve, this can be found where your gas line attaches to the propane tank.

Tep 3 – Attach Hose Adaptor:

Insert one end of the hose adaptor into the tank and place the other end over your house’s pipe. This is usually found in your front yard by your gas meter. Tighten the hose adaptor with a wrench to make sure it’s secure.

Step 4 – Open Each Valve Slowly:

Find the main cold water line that runs through your house and open it up, then do the same for your propane regulator valve (the one attached to your propane tank). Slowly open the main gas line in front of your house.

Tep 5 – Light The Grill:

Turn on the gas valve on your grill and light it up! Be sure to only light the burner closest to the hose adaptor (the one you placed over your house’s pipe). Close all the other valves on your grill and turn the gas off at the tank once it’s lit.

Step 6 – If Applicable:

If you’re experiencing any problems getting your grill to stay lit, and if your house uses a third type of connection (in some states) where there is no adaptor between the outdoor pipe and house line, you’ll need to install a “T” connector and run another pipe from the regulator up into your attic. Then take that line down into your house and then out to where the grill is (the same as step 4). The downside to this method is that it costs more money and time, but if you’re having problems with getting your grill lit, this will solve it.

Check That All Connections Are Secure Before Using Grill For Cooking:

This is the most important step!

Make sure that all connections are tight and secure. Make sure your house’s gas line is completely turned off as well as the tank regulator valve. Then open up your grill valves slowly and light it as usual. Be sure to watch it for a few minutes until you’re sure everything has been connected correctly and that there are no leaks.

If You Find a Leak:

– Close the grill and turn off all valves.

– Turn the main house line back on and open each valve slowly until you can pinpoint which one is leaking (usually very easy to tell). Then tighten any loose connections or replace whichever part of your connection has a problem.

– Once everything is secure, open up each valve and turn on the gas at your tank then light it as usual. Make sure to watch for a few minutes just to be extra careful that there aren’t any other leaks. If you find one, fix it before continuing.

Close All Valves When Not in Use:

Be sure to always close all valves when your grill isn’t in use, this will ensure that there aren’t any leaks and that the gas is completely shut off. Also be sure to never leave a lit grill unattended.

Alternative Methods:

If connecting to a house’s natural gas line is not an option for you, there are some other alternatives such as a propane tank adaptor or a disposable propane canister.

How to Avoid Running Out of Propane Gas For Your Grill?

This is a common problem for people with natural gas grills who forget to turn them off when they are finished cooking. To avoid this, be sure to purchase an adaptor that will shut your grill’s propane off automatically after it has been running for two hours or so. You can also use disposable propane canisters on some grills. More information about these options can be found on this website.

There You Have It!

You now know how to easily convert your traditional charcoal grill into a propane gas grill by connecting it directly to your house’s natural gas line.


All in all, connecting your propane tank or natural gas line to your grill isn’t that hard of a job and the benefits are endless. It only takes about 1 hour to get done from start to finish and can be done by anyone with a little know-how under their belt. If you’re wanting to get rid of your charcoal grill and can’t find a natural gas grill, or even if you just want to save time grilling and have the option to use propane whenever you want, this is definitely an option for you!
