Homeowner needs a way to vent a double bowl island sink with a garbage disposer and dishwasher without using a roof vent or loop vent, but multiple AAVs fail to resolve slow drainage.

Workarounds Described

• removing AAV to let sink drain freely (but risking sewer gas)
• testing multiple AAV brands (Oatey, Studor Redi-Vent, Studor Mini-Vent) without success

Implied Software Gaps

• App that calculates correct vent size and placement for complex drain configurations
• Tool that integrates with building codes to validate venting design
