Abstract
Described herein are embodiments of a drain adapter device configured as a low-profile drain that provides a dry seal between a drain base and an installed floor drain. The low-profile drain is configured to receive threaded drain gates or strainers. In some embodiments, the drain adapter device provides a low-profile drain system that includes universal receiving features configured to engage with strainers, drain gates, caps, and the like.
Claims16
A low-profile drain system, comprising:
- a drain adapter having an upper surface and a lower surface, the drain adapter including a center axis and a bonding flange extending from the center axis to an outer periphery of the drain adapter, wherein the drain adapter includes a stem having an externally-threaded portion;
- and
- a drain insert disposed inside a portion of the drain adapter below the upper surface, the drain insert including an internally-threaded portion configured to threadedly-engage with a drain component other than the drain adapter.
A low-profile drain system, comprising:
- a drain adapter having an upper surface and a lower surface, the drain adapter including a center axis and a bonding flange extending from the center axis to an outer periphery of the drain adapter, wherein the drain adapter includes a stem having an externally-threaded portion and an internally-threaded portion, and wherein the internally-threaded portion is configured to threadedly-engage with a drain component other than the drain adapter.
A drain system, comprising:
- a drain adapter having an upper surface and a lower surface, the drain adapter comprising a center axis and a bonding flange extending from the center axis to an outer periphery of the drain adapter, wherein the drain adapter comprises a center aperture extending between the upper and lower surfaces;
- a drain interface gasket disposed adjacent to the lower surface of the drain adapter, wherein the drain interface gasket is configured to compress upon engaging a surface of a drain;
- and
- a drain insert comprising a threaded stem, wherein the threaded stem is configured to engage with receiving features in a threaded interface adapter disposed between the drain insert and the drain adapter, and wherein a height of the drain insert relative to the drain adapter is adjustable via the threaded stem.
