Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • a floor gully assembly as set out herein and according to a first aspect comprises a floor gully and a water trap comprising a water seal.
  • the floor gully and the water trap each extends in a vertical direction and in a lateral direction, as seen when being in an intended mounted position.
  • the floor gully comprises a gully inlet opening arranged at a gully top, a gully side wall and a gully bottom, the gully sidewall and the gully bottom defining a gully inner compartment.
  • a gully outlet opening is arranged in the gully side wall.
  • the gully inner compartment comprises a water trap receiving portion adapted for receiving the water trap, the water trap receiving portion being in fluid connection with the gully outlet opening.
  • the water trap is adapted to form a seal between the gully inner compartment and the gully outlet opening allowing water flow from the inner compartment to the gully outlet opening only via the water trap.
  • the water trap receiving portion is arranged offset, as seen in the lateral direction x, with respect to the gully inlet opening.
  • That the water trap receiving portion "offset" with respect to the gully inlet opening means that the water trap receiving portion is arranged out of line, in the lateral direction, with respect from the gully inlet opening, as seen in a vertical projection of the gully inlet opening.
  • floor gullies are arranged directly below and in line with the gully inlet opening.
  • the floor gully assembly according to the present disclosure improves the drainage of water from the floor drain and is less space consuming, as seen in the vertical direction, since the water trap is arranged at height with the gully outlet opening.
  • the water trap receiving portion of the gully inner compartment is arranged offset with respect of the gully inlet opening, a larger volume of water may be received by the floor gully prior to passing the water trap, which increases the drainage efficiency.
