What is BS EN 13079 - Air gap with injector for protection of potable water about?
BS EN 13079 is a European Standard on devices to prevent pollution due to backflow of portable water. The main aim of BS EN 13079 is to provide manufacturers with best industry requirements of air gap with injectors such that they play a positive role in the provision of clean and uncontaminated water for human consumption and use.
BS EN 13079 specifies the characteristics and the requirements of air gaps with injector Family A Type D intended for protection of potable water in water installations from pollution.
BS EN 13079 applies to air gaps in factory assembled products and to constructed air gaps in situ, and defines the physico-chemical characteristics of materials of construction used for the purpose and application to ensure compliance with BS EN 13079 during normal working use.
Who is BS EN 13079 - Air gap with injector for protection of potable water for?
BS EN 13079 on air gap with injector for protection of potable water is useful for:
- Air gap with injector and protection assembly manufacturers
- Anyone involved in commissioning and operation of water supply systems
- Quality control personnel
- Local bodies
Why should you use BS EN 13079 - Air gap with injector for protection of potable water?
Type AD - Air gap with injector is a non-mechanical backflow prevention arrangement of water fittings. They are ideally fitted on your home’s water pipes such that water flows in one direction. As a result, backflow prevention devices prevent drinking water from being contaminated with other sources because of backflow.
In this regard, BS EN 13079 provides best industry requirements of materials, as well as protection assembly that includes four integral parts: an injector/upstream feed orifice, a receiving device/downstream receiving orifice, a receiving vessel and an airbreak to drain.
Guidance on the air gap and backflow/back pressure is also covered such that the overflow arrangement is not compromised.
BS EN 13079 also covers verification tests to demonstrate whether the air gap distance during backflow, and air break to drain are in compliance with the requirements.
Thus, if you are a manufacturer of air gap with injector, complying with BS EN 13079 can determine whether or not your products are fit for purpose. As a result, incidents of contamination and potential health risks due to cross connections can be avoided.
