If you have a cross connection, or an installation on your premises with the potential to cause backflow, and subsequent contamination of the water supply occurs, your company may be exposed to:

Of course, having a device is dependent on having your site assessed so that the property’s hazard rating can be determined.

You may already have a backflow prevention device installed within the property however a containment backflow prevention device is required regardless of zone or individual protection. As Yarra Valley Water cannot guarantee the integrity of zone or individual protection on a customer’s site, we cannot guarantee the protection of the drinking water supply from backflow unless the site is contained by an appropriate device at the meter.

A qualified licensed plumber can assess the hazard rating of your business process and determine the type of device you need to have.

This Grant pressure relief valve is used in some Grant oil-fired boilers including Vortex Pro Combis, Vortex Pro Internal and Vortex Eco Wall Hung models. This 3 bar pressure relief valve has a pressure gauge port and it a safety component on boilers.

The internal pipe work arrangements and the processes carried out on the site will dictate the hazard rating for the property.

To eliminate this risk, the installation of an appropriate backflow prevention device is required. It is the responsibility of the owner or occupier to ensure that no backflow occurs.

Given the right circumstances, backflow can occur at any property that is supplied with a water supply connection. If your property is considered a High or Medium hazard risk and you do not have a backflow prevention device installed, your property may contaminate the water supply.

If your property is assessed as a High or Medium hazard risk, then you need a device. If this is the case, you must arrange for the installation of an appropriate containment backflow prevention device. Such a device must be located at the water meter, or all meters if there is more than one.
