Abrégé

A drain assembly for a fluid tank having a drain hole therein may include a hollow first member to be coupled with the drain hole, where the hollow first member has at least one opening therein. The drain assembly may further include a hollow second member slidably coupled with the hollow first member and movable along a longitudinal axis of the hollow outer member between first and second positions. The hollow second member may be configured to seal the at least one opening in the hollow first member when in the first position to define an upper spillover level for fluid within the tank, and to unseal the at least one opening in the hollow first member when in the second position to define a lower spillover level for fluid within the tank below the upper spillover level.
