The invention concerns a built-in component to be arranged in floors with a through-flow housing comprising at least one inlet passage and at least one outlet passage constructed such that through-flow connection devices can be provided. On the housing, in the region of at least one of the passages, the built-in component has a flange member (7) which seals the passage externally with respect to the floor. Said flange member has a pipe-shaped attachment (9) for mounting the connection device. |
