The invention provides a building-water-feeding-pipe integration distribution box. The building-water-feeding-pipe integration distribution box comprises a box unit, a plurality of clamping grooves, a plurality of directly-inserting corrugated sleeve connectors and installing positioning structures, wherein the box unit comprises a box body and a box cover connected with the box body; the clamping grooves are formed in the box body; the directly-inserting corrugated sleeve connectors are arranged on one and/or two and/or three and/or four side faces of the box body and used for allowing tap water pipes and corrugated sleeves with which the tap water pipes are sleeved to pass through; the installing positioning structures are arranged on the box body in the circumferential direction and used for allowing the box body to be installed to a target area. According to the building-water-feeding-pipe system, the building-water-feeding-pipe integration distribution box is adopted, then the arrangement mode of the tap water pipes is parallel, middle connectors are not required for the pipes, construction is rapid, pipe arrangement does not need to be strictly horizontal and vertical, construction is convenient, the connectors in the pipe system are small, the occurrence probability of water leaking is reduced, flow water pressure is stable, and maintenance is convenient.
