Persistent foul odor from under bathroom sink persists even after cleaning p-trap and overflow channel—possible rubber p-trap contributing to smell, unclear cause.

Workarounds Described

• Pulled p-trap and manually cleaned out gunk with brush for 30 minutes
• Pulled drain pipe and removed cup worth of stuck gunk from overflow channel
• Repeated cleaning after 2 days when smell returned

Implied Software Gaps

• Guided diagnostic tool that asks about smell type and suggests targeted checkpoints (rubber p-trap, overflow, etc.)
• App that logs cleaning steps and reminder to monitor if smell returns, with replacement part recommendations
