Backflow

Q: What is backflow?

A: Backflow is the accidental reversal of flow of water, or water mixed with contaminants, into the drinking water supply. If this happens, it can create a health risk.

Backflow prevention is all about keeping drinking water safe. It is mainly associated with commercial or industrial activities, where chemicals and toxins in everyday use present a high health hazard. Think of car washes, beauty salons, dental clinics, dairy farms and meat plants.

In people's homes, swimming pools, spas and fountains are the kinds of installations that require backflow protection to prevent the 'non-potable' water from getting mixed up with the drinking water supply in any way.

Your Master Plumber can offer backflow protection by creating an air gap or installing a backflow prevention device. This is placed as close as possible to the potential source of contamination and in an accessible position for maintenance.

Backflow prevention within a building is the responsibility of the building owner, so if in doubt about any aspect of installation, maintenance or testing requirements, check with your Master Plumber.

It's worth browsing your council website, as some offer useful information on local requirements.
