Abstract

A flood prevention system primarily for domestic water storage and supply systems in which a plurality of channel members 10 are mounted so as to catch any overflow from pipes or tanks (Fig. 3 not shown), and includes support members 12 with recesses 6 to receive the pipework and recesses 4 to allow leaked water to pass therethrough. <IMAGE>

Description

"Flood Prevention System" This invention relates to a flood prevention system, particularly adapted for use in the water supply systems of domestic premises.

It is common problem in domestic premises that the pipework in the water supply system may be caused to leak as a result of bursts caused by freezing, or corrosion as a result of the age of the components. The present invention seeks to provide apparatus for preventing the consequent release of water from causing extensive damage to the premises and/or their contents.

Accordingly, the present invention provides a flooding or overflow prevention system for water supply installations, comprising a plurality of channel members adapted to be mounted so as to support water carrying pipework, and also adapted to be connected together with one another in such a way as to form a continuous channel beneath the run of pipes.

Preferably, each continuous section of channel is installed with an overflow connecting it to the exterior of the premises, to enable particular regions of leakage to be identified.

In a preferred embodiment of the invention, each channel section is provided with support members for receiving pipework of standard sizes, and also a snap on lid so as to enclose the pipework once it has been mounted in the channel. Preferably, the channel member and lid are both made from extruded plastic or aluminium, so that they can be easily cut to length.

The channel sections may also be arranged to form a "moat" around a water tank or cistern to catch any overflow.

Alternatively, in accordance with a further aspect of the invention, there is provided a traylike unit in which a water storage tank may be mounted, and which is somewhat larger in area than the base of the tank, so as to provide an overflow "moat" around the tank. In use, the tray may be connected to an outlet channel member, or may be provided with its own overflow to the exterior of the premises.

embodiments of the invention will now be described by way of example, with reference to the accompanying drawings in which: Figure 1 is a perspective view of a channel section in accordance with the invention, before installation of pipework; Figure 2 is a vertical cross-section through a channel section water as shown in Figure 1; Figure 3 is a perspective view of a tank installation in accordance with the invention; and Figure 4 is an end elevation view of an installed channel member, with pipes exiting downwardly from its end.

Referring firstly to Figures 1 and 2, a channel section member 10 which is preferably extruded from aluminium or plastics material is mounted on joists 8 in a loft (for example) by means of right angle brackets 13.

An insert 12 which may, for example, be moulded from plastics material, fits across the width of the interior of the channel, and is formed with recesses 6 of part circular crosssection, to receive water carrying pipes. In a typical installation, these pipes will be of 15, 25, or 35mm diameter.

The insert is also provided with a slot like cut-out 4 in its base, to enable any water leaking from the pipes to pass beneath the insert.

The upper edges 2 of the side walls of the channel member 10 are preferably flanged, as shown in Figures 1 and 2, so that a flat lid 11, formed with cooperating flanges, can be clipped over the pipes once installed.

Figure 3 shows an installation which includes a channel assembly 10 surrounding inlet and outlet supply pipes extending horizontally through the loft of the building, and in addition comprises a moat like structure 14 constructed from similar channel members and surrounding the base of a cold water storage tank 18 to provide an overflow prevention device for the tank. Preferably, the moat 14 is vented by an overflow pipe (not shown) to the outside of the building. Alternatively, the overflow device 14 may be made in the shape of a large tray, in which the tank 18 is mounted.

Figure 4 shows an arrangement for sealing the end of a channel section 10, where a pair of pipes 17 leaving the end of the channel, are turned downwardly to begin a vertically downward run.

In order to seal the end of the channel, a pair of "stocks" 16, formed with cooperating semi-circular recesses 20, are fitted into the end of the channel to seal it and so that the lower one of the pair forms a support for the horizontal part of the pipes 17, whilst the upper member of the pair holds the pipes. in position in the recesses of the lower member.

Claims

CLAIMS:

1. A flooding or overflow prevention system for premises having water supply installations, comprising a plurality of channel members adapted to be mounted so as to support water carrying pipework, and also adapted to be connected together with one another in such a way as to form at least one continuous channel beneath the run of pipes.

2. A flood prevention system according to claim 1, in which the or each continuous section of channel is provided with an overflow communicating with the exterior of the premises.

3. A flood prevention system according to claim 1 or claim 2, in which the or each channel section is provided with at least one shaped support member for receiving pipework of standard diameters, the support member being formed so as to allow water to flow past it.

4. A flood prevention system according to any preceding claim in which the or each channel section is provided with a snap-on cover.

5. A flood prevention system according to claim 3 or claim 4, in which each said shaped support member comprises at least one substantially semi-circular recess to receive the lower half of a pipe, and in which a co-operating retaining member having a co-operating recess is provided to engage over the upper half of the pipe to secure it in position.

6. A flood prevention system according to any preceding claim which is formed from extruded plastic or aluminium.

7. A flood prevention system comprising a plurality of channel members adapted to be connected together and mounted around a water storage tank or cistern to form an overflow receptacle.

8. A flood prevention system comprising a tray-like unit in which a water storage tank or cistern can be mounted so that overflow can be prevented.

9. A flood prevention system according to any of claim 2 to 6, and further comprising an interconnected channel or tray overflow device according to claim 7 or claim 8.

10. A flood prevention system substantially as herein described with reference to the accompanying drawings.
