The invention relates to a locking element (11) for securing a grate (3). The locking element (11) comprises a spring element (113) kept between a cover element (111a) and a spring support element (117). The spring support element (117) is displaceable relative to the cover element (111a) by means of an actuating element (115). The displacement of the spring support element (117) causes a movement of at least one of the ends (113a, 113b) of the spring element (113) relative to the cover element (111a).

A channel drain for use in a fabricated surface having an exposed appearance. The channel drain includes a first body having a plurality of support surfaces, with each support surface extending from a respective body sidewall in spaced relation to a body lower wall. A plurality of inserts are insertable into the first body. Each insert includes an insert cavity sized and structured to receive a selected material having an appearance substantially identical to the exposed appearance of the fabricated surface. Each insert is supported by certain ones of the plurality of support surfaces when inserted into the first body and is sized and structured to define a gap between the pair of body sidewalls when inserted into the first body, with the gap allowing for fluid to flow therethrough toward the body lower wall.

An inlet filter includes a frame, filter material, a feed stream inlet, and a filtrate outlet. The frame includes a thick portion and a narrow portion. The frame also includes a spring-comprising portion having an adjustable height. A method includes inserting an inlet filter into a storm sewer inlet. The inlet filter can be one of a plurality of inlet filters inserted into the storm sewer inlet, the filters cooperating to filter a feed stream entering the storm sewer inlet. A system includes a plurality of inlet filters configured to be coupled together to filter a feed stream to a storm sewer inlet. The system can be configured so that the width and the height of the plurality of filters is adjustable. For example, a first inlet filter and second inlet filter can be slidably engaged with a connecting filter.

A drain assembly for installation in a shower floor, the drain assembly including a drain body including an upper surface defining a top side, and a lower surface opposite the upper surface defining a bottom side. The drain assembly also defines an aperture extending along an axis through the drain body between the upper surface and the lower surface and includes an outlet having a flange and an elongated body. When assembled, the elongated body is configured to extend below the lower surface of the drain body when the flange rests on the upper surface. The drain assembly also includes one or more fasteners configured to couple the outlet to the drain body to form a water-tight seal therebetween, where each of the one or more fasteners are accessible from the top side.
