Abstract

An improved drain for an above-ground pool is disclosed. A variety of above-ground pool types are considered. Above-ground pools must be drained after use before being stored in a lengthy and time-consuming process. The improved drain can advantageously remain open during the draining process allowing for improved drainage. The drain can comprise a plug member and a locking member. The plug member can be configured to attach to the locking member when open. This and other embodiments are disclosed herein.
