Definitions

  • This invention relates to a floor drain.
  • Floor drains are often provided in bathrooms and kitchens, particularly in high- rise apartments and hotels.
  • the floor drain has a floor-level inlet and is normally provided at the lowest point in a tiled or slabbed floor, such that any water on the floor will flow into the drain.
  • a water seal is provided between the drain inlet and the drain outlet which leads to the waste or soil pipe.
  • Floor drains serve a number of purposes. They are convenient if the floor is being mopped or otherwise cleaned with water, as the water can be directed into the drain and does not have to be collected or lifted. Also, in the event of a basin or bath overflowing, or a shower being used without a shower curtain in place, any water reaching the floor of the bathroom will flow through the drain, avoiding the flooding and water damage problems that would otherwise result. Maintenance of the water seal in the floor drain relies upon maintenance of a sufficient water level in the drain body. In the past, this was normally assured by regular mopping out of the associated floor. However, with use of alternative cleaning methods which use little if any water, a regular supply of water to the floor drain is no longer assured. Thus, there is a risk that the water providing the seal in the drain will evaporate to such an extent that the seal is lost, allowing unpleasant smells, sewer gases or infectious agents to pass through the drain and into the room.
  • floor drains are utilised to accommodate waste water from baths, and are positioned directly beneath bath outlets.
  • floor drains are difficult to access for other purposes, and suds and the like will often build-up around the drain inlet.
  • a method of maintaining a seal in a floor drain comprising: providing a floor drain having a floor-level inlet and a sub floor-level outlet and a water seal between the inlet and the outlet; and providing a supplementary supply of water to the drain to maintain the level of water in the water seal sufficient to maintain a seal between the inlet and the outlet.
  • a floor drain comprising a body having a primary inlet, a secondary inlet and an outlet, in use the primary inlet being located at floor-level and the secondary inlet and the outlet being located sub floor-level, the body being configured to allow isolation of the primary inlet from the secondary inlet and the outlet by a water seal.
  • a floor drain comprising a body having a primary inlet and an outlet, in use the primary inlet being located at floor-level and the outlet being located sub floor-level, the body defining an anti-siphon seal chamber configured to allow isolation of the primary inlet from the outlet by a water seal, the seal chamber having a lower portion and an upper portion, the upper portion defining a larger area than the lower portion.
  • a floor drain comprising a body having a primary inlet, a secondary inlet and an outlet, in use the primary inlet being located at floor level and the secondary inlet and the outlet being located sub floor level, the body defining an anti-siphon seal chamber configured to allow isolation of the primary inlet from the secondary inlet and the outlet by a water seal, the seal chamber having a lower portion and an upper portion, the upper portion defining a larger area than the lower portion.
  • a supplementary supply of water is provided to the drain this will be directed into the drain via the secondary or supplementary inlet.
  • the supplementary inlet is connected to the waste outlet of another fitting, such as a basin, bath or shower, which will normally be provided with its own water seal, upstream of the supplementary inlet. This ensures a more regular flow of water through the drain, and minimises any risk of the water seal drying out. Also, the flow of water between the supplementary inlet and the outlet ensures that the water in the floor drain does not stand undisturbed in the drain for long periods.
  • the supplementary inlet is isolated from the primary drain inlet by the water seal the likelihood of suds and the like passing out of the primary inlet is minimised. Also, the absence of a water seal between the supplementary inlet and the outlet, and indeed the inlet and the soil pipe system, facilitates free flow of fluid between this inlet and the outlet, and free flow of fluid from the associated fitting to the soil pipe system.
  • the provision of the anti-siphon chamber allows the drain to accommodate relatively large flow volumes without the risk of the water seal being compromised by siphonic action.
  • the supplementary supply of water may come from a source other than the waste water from another plumbing fitting.
  • a condensate drain from an air-conditioner, dehumidifier, or tumble-dryer may provide the supplementary supply.
  • the supplementary inlet need not necessarily be isolated from the drain inlet by the water seal.
  • the supplementary inlet may be coupled to the normal cold water supply, or to another source of water, for example roof guttering.
  • a valve may be utilised to control the supply of water to the floor drain. The valve may be manually operable or may operate automatically at timed intervals or in response to sensors indicating that the water level in the drain is below a predetermined level.
  • the floor drain may comprise an inlet tube which extends through the primary inlet into the drain body, the lower end of the tube being below the water level in the water seal.
  • the inlet tube may be removable through the primary inlet, to allow clearing of the drain: as floor drains are typically fitted in tiled, slabbed, or otherwise sealed floors, it is likely that the only access to the drain will be through the inlet.
  • the inlet tube may co-operate with a movable collar or sleeve which is a sliding sealing fit with the lower end of the tube. This allows the effective length of the tube to be varied, accommodating different spacings between the upper end of the tube, which will typically be at or slightly below floor level, and the portion of the body which defines the base of the seal volume. Seals may be provided between the inlet tube and the collar. In one embodiment a pair of elastomeric seals are mounted in locating grooves in the outer face of the tube for co-operating with the inner face of the collar.
  • the collar and tube may be adapted to retain the collar on the tube, for example a lip on the collar may be arranged to engage a tube seal.
  • a portion or spacer may be provided on the lower end of the collar to engage the base of the body and ensure the appropriate spacing of the end of the collar from the base.
  • the inlet tube may include a grill or filter spaced from the upper end of the tube, which grill may be removable for cleaning.
  • the upper end of the tube may include a cover grating.
  • the inlet tube may be adapted to form a sealing fit with the body.
  • an external seal is provided on the tube for engaging an inner wall of the body.
  • the seal may be provided on a cover grating which attaches to the upper end of the tube.
  • the inlet tube may be keyed to a portion of the inlet body to prevent relative rotation therebetween.
  • the body may comprise an adjustable inlet portion for accommodating different floor thicknesses.
  • the body may define a lower flange for engaging the underside of a floor and an upper flange for engaging the floor surface directly surrounding the floor drain primary inlet.
  • the lower flange may be defined by a main body portion and the upper flange by an inlet body portion. The portions may be coupled by a screw thread which allows the spacing between the flanges to be varied.
  • the lower flange may feature a sealing arrangement, such as a gasket, adapted to form a sealing engagement with the underside of the floor.
  • the lower flange may include one or more drain or weep holes which pass from the upper face of the flange into the drain body.
  • the weep holes may communicate with the supplementary inlet and outlet. In certain applications the weep holes may be deemed unnecessary or undesirable, in which case the weep holes may be easily sealed by, for example, a small volume of putty.
  • the floor drain may be formed with the/each weep hole closed, the/each weep hole being open-able if desired.
  • the primary inlet may be sealable.
  • the primary inlet is sealable to prevent fluid exiting the floor drain through the primary inlet.
  • the primary inlet includes a valve.
  • the valve is a non-return valve adapted to permit fluid to enter the floor drain through the primary inlet but prevent fluid from exiting the floor drain through the primary inlet.
  • the non-return valve prevents liquids, gases and infectious agents such as viruses or aerosolised bacteria entering a room from the floor drain.
  • the non-return valve includes a seal element and a seal surface, the seal element adapted to engage, and form a seal with, the seal surface.
  • the seal element is an elastomeric material.
  • the seal element is removable.
  • a removable seal element can be easily cleaned.
  • the seal element may be a diaphragm, flap, floating ball or the like.
  • the seal element may be biased towards the seal surface.
  • the seal element is adapted to be displaced from the seal surface by a flow of liquid entering the floor drain through the primary inlet.
  • the supplementary inlet and outlet may be adapted to receive conventional plumbing fittings, and preferably comprise threaded bosses.

  • water which finds its way onto the floor may pass into the floor drain 10 through the primary inlet 14 and leave the drain through the outlet 18.
  • the supplementary inlet 16 is connected to a basin outlet (not shown), such that water draining from the basin will flow, via a dedicated basin water sealed waste trap, through appropriate piping into the floor drain body 12, through the body 12, and then through the outlet 18.
  • the primary inlet 14 is isolated from the supplementary inlets 16 and the outlet 18 by a water seal, the body 12 being configured such that water will normally lie in the body 12, to the level shown by line W ( Figure 4), such that sewer gases and unpleasant smells from the waste pipe system will be contained and will not find their way through the primary inlet 14 into the room.
  • the supplementary inlet 16 is directly open to the outlet 18, however smells and sewer gases will be trapped in the piping leading to the inlet 14 by the water seal in the trap provided in conjunction with the basin.
  • Water flowing into the drain 10 through the primary inlet 14 will have to negotiate a serpentine path and the water seal between the inlet 14 and the outlet 18.
  • the water flowing through the supplementary inlet 16 may flow directly through the drain 10 to the outlet 18, and thence to the soil pipe system, without displacing the water seal, which facilitates free and quiet flow between the basin and the soil pipe.

  • the outer circumference of the grating 24 includes a locating groove 26 for accommodating an elastomeric seal 28 which provides a sliding sealing fit with the body 12.
  • the upper end of the inlet tube 20 is of relatively large diameter, and the tube 20 tapers inwardly to provide an annular volume between the lower end of the tube 20 and the body 12, to form a seal chamber 30.
  • the narrower lower end of the inlet tube 20 also facilitates flow between the supplementary inlet 16 and the outlet 18.
  • the body 12 is provided with an adjustable primary inlet portion 32 to accommodate different floor thicknesses.
