Abstract
This utility model discloses a weatherproof and breathable cap for building drainage risers, including a weatherproof and breathable cap body. One end of the weatherproof and breathable cap body is a pipe connection port, and the other end is provided with a cap. The cap is detachably connected to the port of the weatherproof and breathable cap body. A set of limiting ribs are evenly provided along the circumferential direction on the inner wall surface of the weatherproof and breathable cap body near the cap port. Each limiting rib has a limiting step on its inner surface to limit the pipe insertion position, which facilitates the installation of the pipe and overcomes the problem of inaccurate installation position of drainage pipes in existing breathable caps.
