Definitions
- a combined inspection gully dish and trap apparatus A combined inspection gully dish and trap apparatus.
- the invention generally relates to a combined inspection gully dish and trap apparatus. More particularly but not exclusively the invention relates a combined inspection gully dish and trap apparatus which allows inspection access and/or ventilation to a sanitary sewer drain.
- a gully trap is a generally U shaped pipe which houses water, the water creates a seal which helps to prevent toxic and/or flammable gases and disease carrying pests from exiting the sanitary sewer drainage system via the gully trap.
- a gully dish is typically located above the gully trap and tops up the water in the trap via a house plumbing fixture that is in regular use.
- the seal of water in the gully trap is prone to being syphoning away through a build-up of back pressure in the sanitary sewer drainage system at the outlet end of the gully trap.
- a terminal vent allows air to flow into the sanitary sewer drain, preventing back pressure syphoning water away from the water seal.
- pressure builds up inside the system, this pressure tries to draw air inside to equalise with the atmospheric air pressure. This creates a syphoning effect on the gully trap, drawing water from the gully trap into the sanitary sewer drainage system, breaking the seal between the sanitary sewer drainage system and the atmosphere, creating a passage for air to flow into the sanitary sewer drainage system.
- the gully trap has a dual purpose, firstly to stop toxic/flammable gases and disease carrying pests in the sanitary sewer drainage system escaping into the living environment as described above.
- the second purpose of the trap is to act as a pressure release system in the sanitary sewer drainage system by allowing effluent to discharge at the top of the gully dish, in the event of a blockage downstream in the sanitary sewer drain, thus preventing the effluent from entering the dwelling.
- the gully dish and gully trap often branches off from the main pipe of the sanitary sewer drain.
- the gully dish and gully trap may be the only means of entry outside the sanitary sewer drain and for this reason entry can be restricted into the sanitary sewer drain, because of the configuration of the piping fixtures involved.
- a blockage occurs then often there is no way around the problem without major invasive inconvenience to the dwelling and/or expensive repairs once access to the drain has been achieved and the blockage cleared.

- an inlet pipe can enter from above and into the top of the dish 2. It will be appreciated both those skilled in the art that the dish 2 can have a number of liquid inlets and in some embodiments the inlet is a removable grate which has apertures in it.
- the apparatus 1 has a ventilation pipe 7.
- the pipe 7 has a removable one way valve 7a connected to the top of it and this valve 7a only allows gases (e.g. air) to enter into the dish 2 via the pipe 7 and not out of the dish 3 via the pipe 7.
- the top of the pipe 7 is at least 150 mm from the top or lid 3 (e.g. grate) of dish 2.
- the vent pipe 7 can come in different lengths and widths and also that the pipe 7 can enter and exit the dish 2 through the side of the dish 2 and need not enter and exit through the top or lid 3 (e.g. grate) of the dish 2.
- the vent pipe 7 can be used as a means of access into the dish 2 and the drainage pipe 5 below the dish 2.
- a user could remove the one way valve 7a in the ventilation pipe 7 and then use a hydrojet to clear out any blockages in the dish 2 and/or sanitary sewer drainage pipe 5 and then insert a camera down the ventilation pipe 7 to check for any damage to the dish 2 or drainage pipe 5.
- the apparatus 1 also has a U shaped gully trap 8.
- the gully trap has a U shaped member 9 which extends from a side wall 10 of the dish 2.
- the trap also has a plate member 1 1 which is formed such that it initially extends diagonally from the opposite side wall 12 of the dish 2 and then extends downwardly such that it is substantially parallel to the side walls 10, 12. This wall extends at least 65 mm in depth past the top of the gully trap, forming the water seal.
- the gully trap 8 partitions the dish 2 into two sections namely a liquid inlet section and a liquid outlet section. When in use the trap houses liquid (e.g. water) which creates a seal between the liquid inlet section and the liquid outlet section.
- liquid e.g. water

- different types of drainage pipe arrangements 5 e.g. inline fig 3, to the side fig 4 or straight down fig 5.
- the connections can be moulded as one piece ready for installation onto a sanitary drain at the appropriate points of connection.
- the connections can vary depending on the proximity of the house to the drain.
- liquid enters into the dish 2 through the pipe 6 (or through apertures in the lid 3 e.g. grate) and into the trap 8 creating a U shaped water seal. Once the seal has been created any excess liquid which enters the dish cascades out of the trap into the outlet section of the dish. The liquid then drains into the sanitary drainage pipe 5 via one of the connections in figures 3-5. Once the water seal has been created in the trap there is equal atmospheric pressure on the inlet section of the trap and the outlet section of the trap. This is maintained by air coming in through the vent pipe 7 with the one way valve 8 on it or an appropriate venting system.
- FIGs 6, 7, 8 and 9 show an alternative embodiment of a combined gully trap and dish apparatus 101 .
- the apparatus 101 has a gully dish 102 which is preferably made from plastic but can also be made from any other suitable materials.
- a removable grate 103 with apertures in it.
- the dish 102 can have a cap instead of a grate 103.
- the gully dish 102 also has a liquid inlet which is a pipe connection joint 104 (or an aperture in an alternative embodiment) adapted to receive a pipe (e.g. from a plumbing fixture) It will be appreciated both those skilled in the art that the gully dish 102 can have more than one liquid inlet 104 and as can be seen in figures 7, 8 and 9 there are four in this embodiment.
- the apparatus 101 has a U shaped gully trap 105.
- the trap 105 is created by a combination of a U shaped member 106 which extends from a side wall 107 of the dish 102 the member 106 then connects to a side wall of a drainage pipe connector 108, wherein the wall is substantially parallel to side wall 107 of the dish.
- the other part of the trap 105 is a gully trap plate member 109 which extends diagonally from the dish opposite the side wall 107 over the top of the pipe connector 108 and then extends downwardly such that it is substantially parallel to the side wall 107 and the side wall of the drainage pipe connector 108. This results in a U-shaped water trap that extends a minimum of 65mm into the water seal.
- the plate member 109 has an aperture in it (not visible) in it and it is also adapted to receive a removable screw top cap 1 10.
- the cap 1 10 preferably is about 100mm in diameter.
- the trap 105 and the cap 1 10 partitions the dish 102 into two sections namely a liquid inlet section and a liquid outlet section.
- the cap 1 10 has an aperture in the middle of it so that a ventilation pipe (not shown) passes through the grate 103 and cap 1 10 and into the liquid outlet section.
- the ventilation pipe preferably has a one way gas valve on the end of it. The ventilation pipe allows air to pass into the liquid outlet section so gas is able to flow from outside the dish into this section and also into the sanitary drainage system via the drainage pipe(s).
- the drainage pipe connector 108 has a substantially horizontal drain connection joint 1 1 1 and a substantially vertical drain connection joint 1 12 with the option of using one or the other for connection to the sanitary sewer drain or both.
- the plate member 109 is connected to the top of horizontal drain connection joint 1 1 1 .
- the member 109 can be connected (e.g. by adhesive or the like) to the side of dish 102 instead of to the joint 1 1 1 .
- the gully trap plate member forms part of the drainage pipe connector 108.
- the apparatus 101 is compact and is able to fit in between floor joists of a multi story building meaning it can be used for both outdoor (drainage) and indoor (plumbing) use.
- liquid enters into the gully dish 102 through the joint 104 and/or through the apertures in the grate 103 and into the gully trap 105 creating a U shaped water seal. Once the seal has been created any excess liquid which enters the gully dish 102 cascades out of the gully trap into the outlet section of the gully dish.
- the liquid then drains into a sanitary sewer drainage system via either the substantially horizontal drain connection joint 1 1 1 or the substantially vertical drain connection joint 1 12.
- a user can open cap 1 10 for access into the sanitary sewer drainage system for maintenance and inspections.
- the apparatus 101 has a ventilation pipe it maintains the atmospheric pressure on the outlet section of the dish such that it is equal to the inlet section.
- the various parts can be made from different materials however in a particularly preferred embodiment of the invention the parts will be made substantially from plastic and more particularly from uPVC (unplasticised polyvinyl chloride polyvinyl chloride) which is highly UV resistant. It also will be appreciated that the various parts of the apparatus 1 can be made in a number of different ways however the parts are preferably made by plastic injection moulding. When the apparatus is made substantially from plastic this makes the apparatus lightweight and inexpensive to produce. In some embodiments the apparatus is modular and the components are preferably pre-fabricated in a factory and are easy to assemble on site.
- uPVC unplasticised polyvinyl chloride polyvinyl chloride
- the apparatus also has a number of additional benefits/advantages.
- the ventilation pipe and/or removable cap allows access into the sanitary sewer system which results in saving time and money as usually excavation is required for access to the sanitary sewer system.
- the ventilation pipe helps to maintain the drain pipes as the ventilation of them causes them to remain drier which helps to prevent the growth of fungus, mildew and other organisms that require a moist atmosphere in which to survive.
- the installation of the combined dish and traps is relatively quick compared to conventional systems and no exaction is required as it can be installed direction over the sanitary sewer drainage system.
- the dish and trap can be placed in one trench and will be directly above and in-line with the sanitary sewer drain pipe which means less excavation, hard fill, backfilling which results in savings in time and cost. By venting the trap it protects it from the failure that occurs when unvented dishes get siphoned by back pressure from sanitary sewer drainage systems.
