The present invention relates to a cover assembly for a drain and vent pipe. The cover assembly comprises an attaching component, a slide latch, a screen wire, a gasket and multiple tooth configuration. The attaching component is positioned between the screen wire and the slide latch. The screen wire is detachable from the attaching component, thereby enabling easy cleaning and replacement of the screen wire. The slide latch includes the gasket made of silicone rubber, which is extruded into a mold into which the multiple tooth are placed. The multiple tooth grips to an outer surface of the drain or vent pipe, and prevents the cover assembly from sliding off during use. The slide latch is attached to the attaching component at one end and to an outer surface of the drain or vent pipe on the other end.
