Direct answer

Faucet is a defined term in the International Plumbing Code (IPC) 2009, in Definitions. The code's own words are: “A valve end of a water pipe through which water is drawn from or held within the pipe.” No other I-Code in this corpus defines it, so the IPC 2009 definition is the one to work from. The term is used in 9 chapters of this corpus, most often in Fixtures, Faucets and Fixture Fittings (IPC 2009), Plumbing Fixtures (IRC 2009), Definitions (IPC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted. Record the jurisdiction, the adopted edition, the application date and any local amendment that rewrites the definition before you use it on a live project, because a term redefined by amendment changes every requirement that depends on it.

Valve — IRC 2009: A device used in piping to control the gas supply to any section of a system of piping or to an appliance.

Faucet: what to open, and in what order

Every row is a document this term depends on. The ICC code library and the ICC adoption maps cover the middle rows.

Frequently asked questions

What is the code definition of faucet?

The International Plumbing Code (IPC) 2009 defines it in Definitions as: “A valve end of a water pipe through which water is drawn from or held within the pipe.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally.

Which parts of the code depend on faucet?

In this corpus the term is used across 9 chapters, led by Fixtures, Faucets and Fixture Fittings in the IPC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own.

What is the definition of a faucet?

In the 2009 I-Codes hosted here it is a defined term rather than a description. The IPC 2009 states, in Definitions: “A valve end of a water pipe through which water is drawn from or held within the pipe.” It is defined in IPC 2009. Because it is a defined term, whatever the adopted edition says it means is what every section using it means — so check Chapter 2 of that edition and any local amendment before relying on this wording.

What does IPC mean in plumbing?

Plumbing is a separate defined term. The IRC 2009 defines it as: “For the purpose of this code, plumbing refers to those installations, repairs, maintenance and alterations regulated by Chapters 25 through 33.” That is not the same as faucet, which the IPC 2009 defines as “A valve end of a water pipe through which water is drawn from or held within the pipe.” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
