Description

TECHNICAL FIELD

This disclosure pertains to a floor gully assembly comprising a floor gully and a water trap and a method for assembling a floor gully assembly.

BACKGROUND

Sanitary products, such as washbasins, bathtubs, saunas and showers are connected to a drainage system, such as a floor drain. The floor drain may be connected to a floor gully assembly for receiving and carrying wastewater to the sewer pipe. To prevent malodours the floor gully assembly may be provided with an odour trap. The odour trap may be a water trap, retaining water after use of the floor drain and the floor gully assembly, and thereby creating an air seal. The air seal prevents gas from passing from the floor gully assembly and back up through the floor drain. Water traps are conventionally cup-shaped and mounted directly beneath the floor drain.
Floor gully assemblies are installed in a building subfloor, such as a concrete floor or a wood floor structure. Floor gully assemblies may be adapted to receive wastewater from more than one inlet, such as for example from a shower and a sauna. For such floor gully assembly a second inlet may be arranged in a gully side wall. Since the inlet openings typically is arranged above the outlet opening of the floor gully assembly, this may add on to the height of the floor gully assembly.
For reasons of fitting into a concrete or wood floor structure of lesser height and for reasons of cost and efficiency, there may be a desire to provide a more compact and flexible floor gully assembly, which is easy and convenient to install as well as cost efficient.
