Embodiment Construction

[0021] In the accompanying drawings, there is a schematically depicted drainage system 10 . System 10 generally includes PVC pipe and fittings. For example, the floor drain 12 passes through the wall at the floor level of the bathroom. However, it could instead pass down through the ground. The primary downspout 13 extends from the floor drain 12 to a U-curved drain air flap 14 . The drain trap 14 discharges via pipe 20 to a cross pipe 19 which in turn is connected to the main downpipe 11 which is ultimately connected to the sewage system below. The main downpipe 11 may extend from one floor to another in a multi-storey building. Extending from the drain flap 14 is an upwardly facing elbow 18 .

[0022] A secondary drain 15 is also provided, which can be located, for example, under a washbasin or a bathtub. The secondary drain 15 has a secondary downpipe 16 extending therefrom. This secondary downpipe 16 is connected to a cross pipe 19 so as to discharge to the main down...

Abstract

A drainage system includes a primary downpipe extending from the floor drain and a trap attached to the primary downpipe. A secondary drain, that is higher than the trap, has a secondary downpipe leading to the sewerage system. An auxiliary pipe extends from the secondary downpipe and periodically delivers water to replenished the trap where evaporation effects can empty water from the trap.

Description

technical field [0001] The invention relates to a drainage pipe anti-air flap in pipeline equipment. More particularly, although not exclusively, the present invention relates to a specific water replenishment system for floor drain traps that may be installed, for example, under bathrooms. Background technique [0002] For example, wall drains providing floor and floor level locations in bathrooms are known. The drainage system includes a drainage air trap between the outfall and the take away pipe to the sewage system. [0003] The problem with such known drain dampers is caused by the evaporation of water from the drain damper. This presents a serious health hazard as sewage odors can 'overflow' through the drain trap and seep out the drain. Contents of the invention [0004] It is an object of the present invention to overcome or substantially ameliorate the above-mentioned disadvantages and / or more generally to provide a water replenishment system for drain traps. ...
