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

Sunday, May 23, 2021

A shut-off valve is not required at the water supply pipes to a bathtub, according to the Residenital Edition of the Florida Building Code (FBC) and the International Residential Code (IRC P2903.9.3). We rarely see a shut-off valve at bathroom tubs, except that older homes that have had a previous problem with supply pipes in the wall may have shut-off valves behind a wall access panel.

    And anyone with a newer house with PEX piping may also have a bathtub shut-off at the manifold. 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.
