Young Blonde Girl With Blue Eyes Shows Off In The Bathtub

Firestopping a bathtub drain
If the bathtub is located in a building with multiple stories, where the floors are required to have a fire-resistance rating, the drain from the bathtub causes a service penetration firestop to be required, which must be built in accordance with the provisions of the local building code. Originally, the drain pipe is made of copper, which is non-combustible. Since the pipe itself will not give way in the event of a fire, the firestop can be made of conventional means, such as firestop mortar or silicone sealant, each topping off a packing material. If the pipe were made of plastic, however, the firestop would likely involve intumescent materials, which would expand in the event of a fire, in order to choke off and seal the melting and disappearing plastic pipe.
