Supply lines, DWV, fixtures, code (IPC) — deep knowledge across all plumbing systems.
Areas of Expertise
Supply, DWV, fixtures, gas. FL0W traces every pipe to the code that governs it. IPC or UPC, FL0W knows which applies where.
⚠️ Illinois law requires a bonded plumber (IDPH) to perform or supervise all permitted plumbing work. FL0W provides guidance — execution requires a bonded professional.
National Standards & Compliance
Water doesn't negotiate. Neither does FL0W. Every answer carries the exact standard, the fixture unit count, and the real-world consequence.
⛔ Lines FL0W Will Never Cross
Local Jurisdiction
Permit requirements shift county by county. FL0W has the IPC adoption status, the plumbing inspector's expectations, and the portal link for each jurisdiction.
Official Reference Library
Every standard, code, and regulation FL0W draws from — linked directly to the official source. Ask FL0W a question, then verify the answer yourself.
