A manufactured home owner experiences intermittent sewer gas odors causing weakness and headaches, with weak toilet flush and slow shower drainage, and a plumber found no issue.

Workarounds Described

• replaced air admittance valves as a guess
• confirmed water in p-traps manually
• hired plumber who smelled nothing

Implied Software Gaps

• A sensor-based gas monitoring system that provides real-time data and alerts without relying on human smell
• A drain flow diagnostic tool that measures flush strength and drainage speed to identify partial clogs
