1. A drain system comprising:
a drain cover positionable over a drain opening in a floor, the drain cover including:
a sidewall extending about a periphery of the drain cover; and
a release surface on the sidewall tapering or sloping inwardly toward a bottom of the drain cover, the release surface arranged to interface with a support frame configured to support and position the drain cover over the drain opening and reduce frictional and shear forces between the drain cover and the support frame during removal of the drain cover from the support frame.
 
16. A drain system comprising:
a construction plug positionable over a drain opening in a floor; and
a plurality of rib members extending downwardly from a bottom portion of the construction plug, the plurality of rib members configured to selectively interact with an inner diameter of a drain pipe fluidly connected to the drain opening and restrict lateral movement of the construction plug over the drain opening.
 
20. A drain system comprising:
a construction plug;
a support frame configured to support and position the construction plug over a drain opening in a tile floor; and
a plurality of rib members extending downwardly from a bottom portion of the construction plug, the plurality of rib members configured to selectively interact with an inner diameter of a drain pipe fluidly connected to the drain opening and restrict lateral movement of the construction plug and the support frame over the drain opening.
