As long as a licensed professional installs your gas lines, you don’t have to do anything extra to prepare for cold weather. If there are pipes that require a wrap, your installer should have done it for you already. If you want to be absolutely sure your gas system is good to go for winter, the best option is to schedule a gas line inspection.

Question 4

What are the benefits of having a gas line installed?

Accepted Answer

•

For one, natural gas is more affordable than electricity, meaning your wallet might see an overall savings over time. The biggest positive of installing a gas line is that gas-powered appliances will still work during a power outage, so your gas fireplace will keep your home warm and toasty during a blackout.

Question 5

What tubing should I pick for my new natural gas line?

Accepted Answer

•

If you're connecting your gas line to appliances, the pro doing the work may recommend flexible corrugated stainless-steel tubing (CCST). Polyvinyl chloride (PVC) with high-density polyethylene (HDPE) is another relatively inexpensive material commonly used for residential pipes. Ultimately, you'll need to find out what is permitted based on the code requirements in your area.
