If you smell rotten eggs or sulfur, hear hissing, or feel dizzy: get everyone out of the home immediately. Don't flip light switches, use your phone indoors, or light anything.
From a safe distance, call NW Natural's 24-hour emergency line at 971-367-8197 and 911. Once the gas is shut off and the area is safe, call us to repair the line.

- Dead or dying plants or grass over a line

- Yellow or orange flames (should burn blue)
- Headaches, dizziness, or nausea indoors
Utility vs. plumber — who fixes what
NW Natural will respond to a reported leak and shut off the gas to make your home safe, at no charge — but the utility does not repair your interior gas lines. That's the work of a plumber.
Once the area is safe, we locate the fault, repair or replace the affected line, and pressure-test the system before restoring service.

Materials, permits & Oregon code
We work with black iron/steel, CSST (flexible stainless), copper, and underground polyethylene gas pipe — chosen for the run and load. Oregon law requires gas piping to be installed by a gas-qualified plumber (OAR 918-695-0020), and most jobs need a permit and inspection.
We pull the permit, install to the Oregon Plumbing & Mechanical Specialty Codes, add the required sediment traps, and leak-test every line before we leave. Unpermitted gas work fails inspection and voids appliance warranties.

What are the signs of a gas leak?
If you suspect a gas leak, leave the area. Do not use switches, phones or other ignition sources in the affected area. Contact the gas utility or emergency services from a safe distance.
What gas lines can you install for appliances?
Stoves and ranges, gas dryers, water heaters, furnaces, fireplaces, BBQs and outdoor kitchens, fire pits, pool and spa heaters, and standby generators — new runs, extensions, relocations and hookups, all to code.
Can I repair a gas line myself?
No — in Oregon gas line work must be done by a plumber, and a mistake risks fire, explosion, or carbon monoxide poisoning. Always leave gas work to a gas-qualified professional.
Do you offer same-day or emergency gas line service?
Yes — same-day and 24/7 emergency service across the metro. For an active leak, evacuate and call NW Natural (971-367-8197) and 911 first, then call us for the repair.
What pipe materials do you use, and what is a sediment trap?
Black iron/steel, CSST (flexible stainless), copper, and underground polyethylene. A sediment trap (drip leg) is a code-required tee-and-cap at each appliance that catches debris before the valve — a common inspection fail when missing.

How the repair scope is decided
After the site is made safe, the repair scope identifies the affected piping, appliance connection and any testing needed. Gas piping, appliance faults and ventilation problems must not be treated as the same diagnosis.
The work may involve replacing damaged piping or fittings, correcting a connection, and arranging the required testing and approvals. Utility procedures determine how service is restored after a shutdown.
Confirm who handles testing, permits and coordination with the utility. Do not assume a completed pipe repair means the appliance is ready to operate or that the utility will reconnect it immediately.
What to have ready before a visit
When arranging non-emergency work, identify the appliance, proposed change, accessible piping and whether the utility has already shut off service. Share any utility notice with the contractor.
