Why You Need RPZ Backflow Preventer Testing in Perth

More than just being a requirement by law, RPZ  backflow preventer testing in Perth is for your own and the community’s safety so that your drinking water and the city or community’s water supply are safe and protected from contaminants.

Just like the rest of the backflow preventers, an RPZ device keeps our water systems safe to use. It’s more often used by houses, buildings, industrial facilities and the like that have their own irrigation systems, fire suppression systems, or sizable boilers. Thus, you can expect to see RPZ devices in big houses, condominiums, many malls and commercial establishments, restaurants, hospitals, and the like.

Having said that, regular testing on your RPZ devices needs to be done to ensure that there are no contaminants present in the irrigation system of the facility coming from fertilizers and pesticides used on the lawn; or in cases of huge boilers or fire suppression systems, that there’s no bacteria or mineral content build-up that would seep into the piping system.

RPZ preventers work by letting the water flow in one direction and preventing it from flowing back. As a safety measure, the relief valve of an RPZ preventer opens up to dump water as a last resort so it won’t flow back into the piping system. If the relief valve continues to dump water, it indicates that there’s an issue with the RPZ device. You will need a licensed tester like Plumbco to check this every year.

Why RPZ Valve Testing in Perth is Paramount

A defective RPZ device poses a danger to everyone’s health, from the ones in the premises to the whole neighbourhood. Health problems and even death are what we will all be facing if a defective backflow device isn’t attended to properly. We do not want that to happen. That’s why there are legislations requiring installation and maintenance of backflow devices such as an RPZ device. These legislations can be found in the Water Services Act 2012 and Water Services Regulations 2013.

Even the Australian/New Zealand Standard 3500.1 requires all builders and developers to have backflow prevention measures in place. This means that an approved backflow prevention containment device needs to be installed at the boundary of every water service connection to the property, including fire services. And it also goes to show how clean, clear, and safe water is vital to our everyday lives.

These regulations also impose penalties of up to $5,000 and $500 per day for instances where it’s found that compliance to fit backflow prevention devices was not followed. Such offences can also result in water service restriction or disconnection. Protecting the drinking water supply is paramount.

Get Your RPZ Backflow Devices Tested & Certified

Because it is required by law to have backflow devices installed, it goes without saying that these devices should be kept functioning properly. For that, you will need a certified plumbing technician to get your backflow preventers like an RPZ backflow device functioning in tip-top shape. The devices need to be inspected, tested, and certified.

That’s where Plumbco’s expertise comes in.
