A homeowner/DIYer cannot figure out how to properly vent a toilet drain line given Kentucky code restrictions and space constraints, risking code violation or structural damage.

No guidance tool exists that accounts for local plumbing code (Kentucky disallows wet venting) and specific joist/floor constraints to propose compliant, safe vent routing options.
