Gas smell: safety comes first

Leave now. Take people and pets out. Do not hunt for the source.
Avoid sparks. Do not use light switches, the garage door opener, a lighter or a phone while inside.
Call from outside. From a safe distance, call 911 and Southwest Gas at 877-860-6020.
Stay out. Return only after responders or the utility tell you it is safe.

Southwest Gas is the gas utility for the City of Phoenix. Some homes on the outer edges of the metro have no utility gas and run on propane or are all-electric; if you are unsure, the provider's name is on your gas bill.

Where the plumber's work begins

The utility looks after its mains, the service line to your meter and the meter itself. Piping on the house side of the meter, feeding the furnace, water heater, range, dryer and any outdoor appliances, is the owner's to maintain. Once the utility has made a leak safe, a plumber can find and repair the problem in that piping.

Outdoor lines and digging

Backyard gas runs usually mean a trench. Arizona 811 says the law requires contacting it before digging, the call is free, and locators get two full working days to respond. Private piping you or a past owner installed may not be marked, so share whatever you know about buried lines.

Permits and cost

City of Phoenix Planning and Development lists Repair/Replace Gas Line among its residential online permits, so ask the plumber who will pull it and schedule the inspection. Cost depends on the length of the run, how many walls or floors it crosses, whether existing pipe can carry the added load and how much trenching is involved.

Gas Line Services questions from Phoenix homeowners

What do I do if I smell gas in Phoenix?

Leave the house right away without touching switches, then call 911 and Southwest Gas at 877-860-6020 from a safe spot outside. Stay out until you are told it is safe.

Does Southwest Gas fix leaks inside my house?

The utility responds to emergencies and maintains its lines and meter. Repairs to piping after the meter are generally the owner's and are done by a plumber.

Can a plumber run gas to an outdoor kitchen or fire pit?

Yes. Expect trenching, a call to Arizona 811 before digging, and a permit and inspection through the City.

Does a tankless water heater need a bigger gas line?

Often it does, because tankless units draw much more gas than tank heaters. A plumber can check whether the existing piping is sized for the load.
