Gas Leak Repair questions, answered by experts

Yes, most states require a plumber to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. Check our state licensing tool to review the local plumber guidelines.

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification, which include:

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

No, you shouldn't cap a gas pipe with a compression fitting because they aren't designed for gas lines and can pose serious safety risks. Gas pipes require threaded caps that create a secure, leak-proof seal capable of handling gas pressure. Using a compression fitting could lead to dangerous gas leaks—a hazard you definitely want to avoid. 

Take this one seriously! If your oven smells like gas when it’s off, this is a telltale sign of a gas leak that can lead to a fire or explosion. In addition, a small leak has the potential to turn into a major leak without warning if any part of your piping or tubing breaks. Potential sources of a leak include the gas valve, burner, joint, or connection lines behind the stove. If the leak appears to be significant, you should contact the gas company or fire department.  

Even though their jobs sound similar—both professions work on pipes—a plumber and pipefitter actually have very different jobs, and pipefitting isn’t considered plumbing. Pipefitting is done in commercial and industrial buildings and factories, and the pipes carry gas, chemicals, acid, and other potentially hazardous substances. Pipefitters often work in intense conditions while plumbers may work in lower-pressure environments.

In North America, pipe measurements are listed as the nominal pipe size (NPS). This measurement refers to the outside diameter. As an example, a 1/2-inch copper pipe has an outside diameter of 5/8 of an inch. If a hardware store lists a pipe as having a 2 NPS, it means that all the pipes with this measurement have a 2 ⅜-inch outside diameter, regardless of wall thickness and inside diameter.
