1. A toilet system comprising:
- a cistern for containing flush water;
a toilet having a bowl, the bowl having one or more apertures which are in fluid communication with a water intake aperture of the toilet and through which flush water flows when the toilet is flushed;
a conduit for transporting flush water from the cistern to the water intake aperture; and
a gas removal device positioned around the conduit and defining an inner aperture through which the conduit passes, there being a peripheral space between the exterior of the conduit and an inner surface of the inner aperture, the gas removal device being operable to suck gas into the device through the inner surface of the inner aperture and comprising a liquid detection mechanism to detect the flow of liquid through the conduit and cease the sucking of gas into the device upon such detection.

18. A toilet system comprising:
-
a toilet having a bowl, the bowl having one or more apertures which are in fluid communication with a water intake aperture of the toilet and through which flush water flows when the toilet is flushed; a cistern for containing flush water, the cistern having an outlet through which flush water is ejected when the toilet is flushed, the cistern and the toilet being arranged such that, when flush water is ejected from the cistern through the outlet thereof, a flow of flush water follows a flow path and is received through the water intake aperture of the toilet; and a gas removal device having an inner aperture, the gas removal device being positioned around the flow path such that the flow path passes through the inner aperture and, when water flows along the flow path, an air gap exists between an inner surface of the inner aperture and an exterior of the flow, the gas removal device being operable to suck gas into the device through the inner surface of the cistern outlet, and comprising a liquid detection mechanism to detect the flow of liquid through the inner aperture and cease the sucking of gas into the device upon such detection. - View Dependent Claims (19)

20. A gas removal device for use with a toilet system comprising a toilet having a bowl, the bowl having one or more apertures which are in fluid communication with a water intake aperture of the toilet and through which flush water flows when the toilet is flushed and a cistern for containing flush water, the cistern having an outlet through which flush water is ejected when the toilet is flushed, the cistern and the toilet being arranged such that, when flush water is ejected from the cistern through the outlet thereof, a flow of flush water follows a flow path and is received through the water intake aperture of the toilet, the gas removal device:
-
defining an inner aperture; being adapted to be positioned around the flow path such that the flow path passes through the inner aperture and, when flush water flows through the flow path, an air gap exists between an inner surface of the inner aperture and an exterior of the flow; being operable to suck gas into the device through an inner surface of the inner aperture; and comprising a liquid detection mechanism to detect the flow of liquid through the cistern outlet and cease the sucking of gas into the device upon such detection. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A method of adapting a toilet system, the toilet system initially comprising a toilet having a bowl, the bowl having one or more apertures which are in fluid communication with a water intake aperture of the toilet and through which flush water flows when the toilet is flushed and a cistern for containing flush water, the cistern having an outlet through which flush water is ejected when the toilet is flushed, the cistern and the toilet being arranged such that, when flush water is ejected from the cistern through the outlet thereof, a flow of flush water follows a flow path and is received in the water intake aperture of the toilet, the method comprising the steps of:
-
providing a gas removal device, the gas removal device defining an inner aperture, being operable to suck gas into the device through an inner surface of the inner aperture, and comprising a liquid detection mechanism to detect the flow of liquid through the cistern outlet and cease the sucking of gas into the device upon such detection; and positioning the gas removal device around the flow path such that, when flush water flows along the flow path, an air gap exists between the inner surface of the inner aperture and an exterior of the flow.
