Troubleshooting

Work the smell, not the spray.

Start with the closest match. Checklists save on this device so you can pick up after a dump run or a hardware-store trip.

Toilet, vent, valve, and treatment.

Sink, shower, and a dried trap.

Leaks, cushions, AC, lockers.

Food, drip pan, cooling unit.

Safety checklist. Don’t skip this one.

Pets, rodents, fabrics, filters, mystery sources.

Parking for a season? Use the storage checklist so you don’t come back to a science experiment.
