A drain plug for sealing the waste and overflow drain assemblies during construction and system testing. A threaded bolt extends through a rubber washer. The bolt is screwed into a tapped hole in the shoe assembly of the drain, providing a secure plug that will not blow out during system testing. A sleeve may be employed on the bolt to allow ease of access to the bolt when deep drains are plugged.
