An apparatus and method for installing an adjustable height drain onto a conduit in a layer of hardenable material. The drain includes a grate member adjustably connected to and in fluid communication with a base member. A connection member connects the grate member and base member and is adjustable to allow the elevation of the grate member to be adjusted in relation to the base member. A spacer is disposed substantially adjacent at least a portion of the connection member to limit hardenable material from setting around the connection member when a layer of hardenable material is poured.
