Description

p:\WPDOCS\DYSSpdemi\7828263 inmov fsdc-30 3w,, 2003 -1- VENTILATED SANITARY PLUMBING SYSTEMS The present invention relates to sanitary plumbing systems and more particular, to forcefully ventilated sanitary plumbing systems.
Typical methods of vertically transporting sewage are disclosed in the Australian National Plumbing and Drainage Code for sanitary plumbing AS/NZS 35002.2:1996. These known methods comprise varying degrees of inefficiency when applied to multi-storey buildings.
Difficulties arise in achieving sufficient ventilation to the sewerage network of, such as, multi-storey residential and hotel buildings.
The reference to any prior art in this specification is not, and should not be taken as, an acknowledgment or any form of suggestion that the prior art forms part of the common general knowledge in Australia.
Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
The present invention proposes a forced ventilation system for directing fumes and odoriferous vapours down a vertical sanitary stack to a position below a lowermost sanitary inlet to the vertical stack where a ventilating pipe is connected for directing the fumes and vapours to an atmospheric discharge location. By providing a continual air stream vertically down a stack at a predetermined flow rate, pressure and velocity having regard to the length, diameter and design sewage loads to be carried by the stack it is possible to avoid exhausting foul odours and vapours from each stack for their re-direction to the ventilating pipe.
Preferably, a fan is installed at or adjacent an uppermost position on the stack to P:\WPDOCS\DYS\pcCi\7828263 innov rs.doc-30 Jwe 2003 -2force the fumes and vapours down the stack and into the ventilating pipe.
In a preferred form a plurality of forced ventilation vertical sanitary stacks connect to a single sewerage line; at or near that connection there is located a ventilating pipe to discharge the fumes and vapours to atmosphere at a suitable location remote from the stacks.
More preferably, a fan is installed in the ventilating pipe to drive the fumes and vapours to atmosphere at the discharge location. Such a fan is sized to accommodate the aggregate airflow of all individual vertical sanitary stacks feeding to the ventilating pipe.
By employing means for directing a controlled airflow into a sanitary piping network it is possible to better control the performance of the water/air relationship within vertical and horizontal piping in the sewerage network. With such control, the requirement for separate and independent ventilation throughout a multi-storey residential type building is negated.
The present invention will now be described by way of example with reference to the accompany drawings, in which: Figure 1 is a schematic of a portion of an embodiment of a sanitary piping plan of a multi-storey residential building; and Figure 2 is an isometric view of a roof top fan arrangement for use in the embodiment of Figure 1.
In Figure 1 there is shown an embodiment of the present invention displaying three vertical sanitary stacks 10. Each stack 10 includes a top mounted fan 11 which runs continuously to create an airflow down its respective vertical sewer line 12.
Each line 12 feeds fumes and vapours into a branch line 13 or 14, each of which P:\WPDOCS\DYS\SpWie\7828263 inmov f.doc-30 Jaea 2003 -3connect to a main sewer line 15 to discharge those fumes and vapours, under the action of fan 17 in ventilating pipe 16, to atmosphere at a lawful point of discharge.
Under the airflows induced by fans 11 and 17 the vapours and fumes in the vertical lines 12 are exhausted downwardly to branch lines 13, 14, and along ventilating pipe 16 to atmosphere while sewage flows down lines 12 into branches 13 and 14 and away from the building via line 15. Fans 11 and 17 may be run continuously or intermittently as desired.
The roof mountable fan shown in Figure 2 comprises housing 20 containing an inline fan portion 21, stack 22, vent cowl 23 and roof level flashing 24.
Finally, it is to be understood that the inventive concept in any of its aspects can be incorporated in many different constructions so that the generality of the preceding description is not to be superseded by the particularity of the attached drawings. Various alterations, modifications and/or additions may be incorporated into the various constructions and arrangements of parts without departing from the spirit or ambit of the invention.

Claims (5)

1. A method of ventilating a vertical sanitary stack in a multi-storey building including applying forced ventilation to the stack from the top toward the bottom of the stack and drawing off fumes and vapours from the bottom of the stack to be exhausted to atmosphere remote from the stack.
2. A method as claimed in claim 1 comprising a plurality of said vertical sanitary stacks including joining the stacks to a main sewer line and wherein the main sewer line is forcibly ventilated to atmosphere at a location remote from the plurality of stacks.
3. A system for ventilating a vertical sanitary stack in a multi-storey building, said system including a fan for blowing air down the stack to a ventilating pipe connected below the lowermost sanitary inlet to the stack, said ventilating pipe exhausting to atmosphere remote from the stack.
4. A system as claimed in claim 3 wherein the ventilating pipe is forcibly vented by a fan which draws off the gaseous contents of the ventilating pipe to atmosphere.
5. A method of ventilating a vertical sanitary stack in a multi-storey building substantially as hereinbefore described with reference to the accompanying drawings. Dated this 1st day of July, 2003 STEPHEN PAUL HOLDINGS PTY LIMITED By Its Patent Attorneys DAVIES COLLISON CAVE
