PlumbingDiagnostics & Troubleshooting3MediumHomeowner$ implied
A persistent sewer smell in a bathroom sink that cannot be eliminated by replacing the P-trap, likely due to inaccessible mold or bacteria in the internal overflow chamber.
Existing solutions like replacing hardware (toilet wax ring, P-trap) and physically plugging the overflow hole are temporary hacks; no product allows homeowners to inspect, clean, or treat the internal overflow passage without disassembly or professional help.
