ABSTRACT:
A drainage system is disclosed for building framing systems comprising weep holes for draining water from an interior cavity to the exterior of the buildilng. The drainage system comprises a weep valve overlying a weep hole in a frame member which provides a passage for infiltrated water from a glass pocket to the exterior of the building while at the same time preventing air infiltration. The weep valve includes a membrane of an elastomeric or other suitable material having a slit formed therein which permits water to seep out. The slit seals sufficiently tightly that, when the framing system is under windload, airflow back through the weep hole is substantially eliminated. Since water infiltration is a result of air infiltration, water infiltration is thus also substantially eliminated.
