Mini floor drains

Mini drains

Mini drains are used in places where, for hygienic and aesthetic reasons, stainless steel elements must be used, and the small amount of water collected allows for the use of a smaller drain diameter.

All ATT floor drains and inspection chambers are made of stainless steel as standard: AISI304 (EN 1.4301) and AISI316L (EN 1.4404). The type of drain depends on the load class, the amount of liquid (medium) to be drained and the design parameters (e.g. ceiling thickness).

ADVANTAGES OF DRAINS

• choice of grating depending on application and load class,
• easy installation,
• thanks to the appropriate siphon design, each drain also serves as an inspection point for the sewage system,
• simple design,
• easy to keep clean.

SELECTION OF DRAINS
Drains are selected based on two basic parameters:

• the amount of wastewater discharged (selection of the appropriate drain diameter and upper part size),
• size, type and intensity of load (the load-bearing element is a grate, which, depending on its type and height, will transfer the specified load).

DESCRIPTION OF INDIVIDUAL DRAIN
COMPONENTS

• Bodies – their round shape limits the accumulation of dirt and ensures easy removal. Welded areas are properly ground to eliminate sharp edges. This
  prevents the possibility of injury during installation or cleaning.
• Grates – available in various shapes, sizes and finishes. Grates are selected according to the load class and installation location of the drain. We offer the following types of grates: lattice – non-slip, ladder, plate and sheet metal – perforated.
• Settling baskets – recommended for use in cases where there are large amounts of solid contaminants in the discharged sewage.
• Strainer baskets – used in the case of small amounts of solid contaminants.
• Siphons – characterised by high functionality and simple operation. They provide easy access to the sewer pipe, quick cleaning and the ability to check the tightness of the installation.

INSTALLATION OF ONE-PIECE DRAINS

1. The sewer connection should be brought to the appropriate height.
2. Place the drain in the drain pipe socket so that the top of the drain is 1-2 mm below the top layer of the floor.
3. Fill the space with concrete.
4. When concreting, do not allow the top of the drain to narrow, and remember to fill hard-to-reach areas thoroughly with concrete.

INSTALLATION OF TWO-PIECE DRAINS

1. We begin installation by embedding the lower part of the drain in the structural layers of the ceiling. The lower part should be embedded in a 15–20 [mm] recess to ensure proper drainage of condensation from the horizontal insulation to the drain.
2. We install damp-proof insulation for the ceiling and secure it with the pressure ring of the lower part.
3. The next step is to position and level the upper part of the drain at the specified elevation. The edge of the upper part of the drain should be 1-2 [mm] below the floor surface.
4. Once the upper part has been stabilised, the remaining floor layers can be installed.
5. Fill the space with concrete.
6. When concreting, do not allow the top of the drain to narrow, and remember to thoroughly fill hard-to-reach areas with concrete.
