The service call: gas odor. Episode seventy of the Gas Service Animated series.

The board flags it priority: odor of gas in the kitchen, intermittent, two days. Everything about this call runs on the leak season's rules — and rule one starts on the phone: keep people out of the space, no switches, no flames, we're on the way. An odor call is a life-safety call until proven otherwise.

On arrival you stage like it matters, because it does. Instrument on and zeroed in fresh air outside. At the door you ask before you enter: anyone feeling ill, any appliances running, when's it strongest? 'When we cook.' Noted — a clue, not a conclusion. Then in, meter first, sweeping as you go.

The sweep says low numbers at the floor, nothing at the ceiling — natural gas rises, so floor-level readings near the range say close-range source, not a filled room. The systematic survey: meter set outside, clean. House line, clean. Behind the range: the flex connector, the shutoff, the range valves — and the meter wakes up at the range's rear manifold.

Now pinpoint like the code says: bubble solution, never a flame. The connector's tight. The shutoff's tight. But the manifold nut behind the burner tray blooms bubbles on the second brush. Confirmed. It only leaks meaningfully when the oven valve cycles — which is why it smelled strongest when they cook. Intermittent odor, intermittent source.

Make it safe in the order the season taught. Appliance valve off. Ventilate the kitchen. Confirm the space reads zero everywhere before anyone relaxes. This one's a repairable joint: crack it, clean it, dope it, remake it, and re-test with bubbles and the meter at operating pressure — clean.

Then prove the whole appliance, not just the fixed joint. Every burner lit and stable. Oven cycled twice, sniffing the manifold under load with the instrument — zero. And because a kitchen leak means a kitchen appliance got attention: a quick carbon-monoxide check over the burners, air-free numbers in range. Fixed and proven.

The customer gets the education that prevents the next call: what the smell means, why the response is switches-off-and-out, the emergency number for next time, and what you found and fixed. Two minutes of talk that might matter more than the wrench time.

And the honest branch: if that sweep had found the space climbing instead of trace — or anything at the meter, in the walls, or under the house — the call flips from repair to make-safe: people out, ignition dead, gas off at the meter, emergency line. You always drive to a repair hoping, and staged to evacuate.

The odor call in one breath. Stage on the phone, zero the meter outside, question before entering. Sweep, survey, pinpoint with bubbles. Make safe in order, repair, re-test under load, and prove the appliance. Educate — and never forget the escalation branch. Next call: the water-heater swap.
