Backflow is a dangerous issue that can result in contamination of the public water supply. This occurs when the flow of water reverses in a plumbing system, drawing non-potable fluids such as pesticides and fertilisers into the drinking water line. This problem is easily prevented by having backflow prevention devices installed at critical points in a water system. Backflow preventers are required by the government to be installed at all properties with connections to the public water supply, including apartment buildings, restaurants and other commercial places.

Plumbers who specialise in backflow prevention know how to install and test these important devices. During the installation process, the plumber performs a backflow hazard assessment to determine the type of backflow prevention device that is needed for the property. The hazard rating is determined by the potential contaminants that could enter the drinking water supply from the property’s plumbing systems. Typically, properties with high backflow hazard ratings are fitted with testable backflow preventers that have valves that can be tested to ensure that they are working correctly. Low hazard properties can be fitted with non-testable backflow preventers that do not need to be tested.

There are many different types of backflow prevention devices. A common type is an air gap, which includes a check valve and a vacuum breaker that creates a physical break between the drinking water supply and any non-potable plumbing. A reduced pressure zone (RPZ) backflow preventer is designed to work in a similar way to an air gap, but has two check valves and a monitor chamber in between to check the pressure. This type of backflow prevention device is commonly used in commercial buildings and apartments, where there is a higher risk of contamination.

Another popular type of backflow preventer is the double check valve assembly, which has two check valves that are connected in parallel to each other. These devices are typically installed at the water meter to prevent water from being pushed back into the city water supply, and they can be used for both low and medium hazard properties. In some cases, this type of backflow prevention device may be required by law for certain types of property, including fire sprinkler systems.

Testing

Backflow testing is a crucial service that ensures your water supply is safe and clean. The service involves a plumber assessing how well backflow preventers work by checking their pressure levels. If they’re working properly, the backflow preventer device will keep untreated or contaminated water from being “back-siphoned” into your home’s clean water supply. However, if the valves fail, contaminant-filled water could enter your home and make you sick.

While it’s easy to assume that a backflow prevention system is sufficient, you need to make sure it works correctly. Your plumber will use a backflow testing kit to test the backflow preventer’s valves and gauges for any signs of problems. For example, they’ll check to see if the valves close when they should and if the air ports are opening up when they should. They will also take the time to look for any cracks or other damage to the device.

The testing process takes a while because the backflow preventer will have to be shut off while your plumber opens and closes the valves on it. They’ll also be testing the gauges, so they may need to stay on site for a few hours. The good news is that the testing services are usually covered by insurance, so you shouldn’t have to pay extra for it.

If you have a high-hazard property, you’ll need to have your backflow device tested at least once a year. Your plumber will carry out a backflow hazard assessment to determine whether your property is classified as low, medium or high-risk. Your plumbing contractor will then install the proper backflow device for your property.

Getting backflow prevention certification is an excellent way for plumbers to show their commitment to the industry and build trust with clients. It’s also a great way to stand out from the competition, as it shows that you understand and can handle an issue that could potentially be very dangerous for people.
