# Plumbing

> US plumbing code compliance and safe drinking water practices for tradespeople and contractors: state-adopted plumbing code amendments, EPA lead and copper rule guidance, and EPA WaterSense fixture certification — grounded exclusively in state plumbing board regulations, EPA.gov guidance, and state licensing board technical bulletins. The Uniform Plumbing Code (UPC) and International Plumbing Code (IPC) are licensed model codes; provisions are referenced by section number only, never reproduced.
