In the know: How bathroom plumbing works

The International Plumbing Code (IPC) is a model plumbing code that sets minimum regulations for plumbing systems with the aim of protecting life, health, and ensuring safety of building occupants. While this model is comprehensive, each country has its own set of regulations, discuss so it is important to make sure you follow the guidelines of where you are based. Also, it is ideal that you consult with a licensed plumber or let him/her perform the work and assemble the pipes on site to prevent implacable or dangerous accidents. You’ll use a 1/2-inch pressure pipe for your supply lines that run from the fixture to the larger 3/4-inch supply lines that run through the house.
