The last half century has seen little change to building drainage systems, this in spite of the fact that, without improvement, buildings continue to experience the following problems:
• Insects breeding and entering the house through the drainage u-bend.
• U-bends drying out, allowing more insects and germ-infested vapour into the house.
• Pressure differences causing back-flow through drainage and toilet systems, a factor that is believed to have contributed to the spread of serious illness in recent years.
• No effective barrier between foul and fresh water drainage.
The “ABF Non-Return Drainage” is the culmination of extensive research into many designs, and has been proven in tests as an effective and simple solution to the above problems. The device comes in two sizes that fully match the British and Hong Kong standard of drainpipe sizes.
We believe that the key to the ABF Non Return Drainage device is its simplicity, which in turn, results in the following features:
- Health – the potential social and economic benefits offered by the ABF Non-Return Drainage system, in terms of the health and environment of our homes, are immeasurable.
- Reliability – the minimization of moving parts in a design that uses gravity and magnetic force, without the need for springs, prevents the danger of constant maintenance problems. The device has been tested in factory conditions, which simulate many varied and extreme environments.
- Durability – tough materials have been used in the construction of the ABF Non-Return Drainage device, with no exposed metal parts, ensuring many years of service, which we believe will match the life of the rest of the drainage system in which it is incorporated.
- Compatibility – The ABF100 fits toilet systems, while the ABF50 fits all standard washbasins, bathtubs and floor drain systems.
- Ease of Installation – The ABF Non-Return Drainage system may be installed into existing systems in a simple and relatively quick operation, causing minimal disturbance to the occupants of the building. It can even be installed without removing the existing u-bends, if so desired.
- Cost – the simplicity of design and installation mean that the cost of employing the system, whether as part of the design of a new building, or into an existing system, is minimal.
- Accessibility – Having successfully patented the ABF Non-Return Drainage, we hope to make the device widely available at outlets throughout Asia and the world. The device is available right now by contacting Faindes International Ltd.
