Abstract

See full text

An extendable drain configured to move between a retracted position and an extended position includes a housing and a drain member. The housing includes a top, a bottom, and a sidewall including an annular stretchable sleeve. The housing defines an interior volume configured to be at least partially filled by a fluid causing the annular sleeve to stretch axially, thereby increasing a distance between the top of the housing and the bottom of the housing. The drain member includes an open top fixed to the top of the housing, an open bottom, and a sidewall extending between the top and the bottom of the drain member through the interior volume of the housing. At least partially filling the interior volume of the housing moves the drain member axially causing the sleeve to stretch, thereby increasing the distance between the top of the housing and the bottom of the housing.
