Does code require a water shut-off valve at toilets?

Sunday, May 23, 2021

A shut-off valve is required at the supply pipe to every toilet in a home, according to the Residenital Edition of the Florida Building Code (FBC) and the International Residential Code (IRC P2903.9.3).

    The code further says that “fixture valves, when installed, shall be located either at the fixture or at the manifold” (P2903.8.5). A manifold is a central water distribution box, similar in concept to an electric panel, in that it has two rows of shut off valves, each of which connects to a pipe that goes directly to a specific plumbing fixture only. Plumbers call it a “home run” system, and we have only seen a manifold used with flexible PEX (cross-linked polyethylene) plastic pipe.
