drainplug
Tub water keeper
A drainplug is a stopper that seals a drain hole, allowing a container to hold liquid until the plug is removed.
Bathtubs, sinks, and oil pans have drainplugs.
To pull the drainplug is to release what's being held—literally or figuratively: Management pulled the drainplug on the whole project.
