Ask Professor Alvin

Plain English first, then the IPC, UPC, IFGC, IRC, or Texas law — with section references.

Howdy — I'm Professor Alvin, your personal plumbing professor.

Before I give you a code-specific answer, what's your jurisdiction (state, county, or city)? That way I can match it to the right code — IPC, UPC, IFGC, IRC, Texas plumbing law, or your local AHJ.

Tip: Tell Professor Alvin your jurisdiction (e.g. "Houston, TX") so every code answer matches the edition your AHJ has adopted. Professor Alvin can be wrong — always verify code-critical answers with your local AHJ.
