FAQ

Everything You Need to Know About Backflow Prevention: Your Questions Answered

We know that backflow prevention might sound like a complex topic, but it’s a crucial part of ensuring that the water in your structure stays clean and safe. We’ve compiled a list of frequently asked questions to help you understand what backflow is, why it’s important to prevent it, and how we at Dor-Mar can help. Let’s dive in!

1. What is backflow? 

Backflow happens when water in your plumbing system flows in the opposite direction of where it’s supposed to go. This can allow contaminated water to mix with your clean water supply, which is definitely something we want to avoid!

2. What causes backflow? 

Backflow can be caused by a variety of things, but it usually happens when there’s a change in water pressure. For example, if a water main breaks or a fire hydrant is used, it can cause the water in the pipes to flow backward.

3. Why is backflow prevention so important? 

Backflow prevention is crucial because it helps keep our drinking water safe. When backflow occurs, it can introduce contaminants like pesticides, fertilizers, or even waste from toilets into our clean water supply. Preventing backflow means preventing these harmful substances from making their way into our homes.

4. How does Dor-Mar help prevent backflow? 

At Dor-Mar, we offer a range of backflow prevention services. Our certified technicians, including Greg Brewer II who has a Backflow Technician Certification, Class A, can test your backflow prevention device, make sure it’s working properly, and perform any necessary maintenance or repairs. We also help with the installation of backflow prevention devices and ensure that your system is compliant with local regulations.

5. What kinds of backflow prevention devices are there? 

There are several types of backflow prevention devices, including reduced pressure zone devices, double check valves, and pressure vacuum breakers. The type of device you need depends on your specific plumbing system and the potential risks associated with it. Our team at Dor-Mar can help determine the best device for your needs.

6. How often should my backflow prevention device be tested? 

It’s generally recommended that backflow prevention devices be tested at least once a year. Regular testing helps ensure that the device is functioning properly and can prevent backflow from occurring.

7. What kind of maintenance does a backflow prevention device require? 

Backflow prevention devices require regular maintenance to ensure they are working correctly. This can include cleaning the device, checking for and replacing worn-out parts, and making sure that all components are in good working condition. Our team at Dor-Mar is equipped to handle all of your backflow prevention maintenance needs.

8. How do I know if my structure needs a backflow prevention device? 

If your home is connected to a public water supply, there’s a good chance you need a backflow prevention device. This is especially true if you have an irrigation system, a swimming pool, or anything else that connects to your plumbing system and has the potential to introduce contaminants into your water supply. Our experts at Dor-Mar can assess your home and help determine if a backflow prevention device is necessary.

9. Can I test or maintain my backflow prevention device myself? 

Backflow prevention device testing and maintenance should be performed by a certified professional. This ensures that the device is tested accurately and that any necessary repairs are done correctly. At Dor-Mar, our certified technicians have the knowledge and experience to properly test and maintain your backflow prevention device.

10. What is the most common type of backflow preventer? 

One of the most common types of backflow preventers is the Reduced Pressure Zone (RPZ) assembly. This device is widely used because of its reliability and effectiveness in protecting water supplies from both backpressure and backsiphonage, in various risk scenarios.

11. What is the most reliable backflow prevention device? 

While the reliability of a backflow prevention device can depend on the specific application and installation, the Reduced Pressure Zone (RPZ) assembly is often considered one of the most reliable options. It has two independently acting check valves, along with a pressure differential relief valve, providing a high level of protection against backflow.

12. What is the difference between a regular backflow preventer and a Reduced Pressure Backflow Preventer? 

A regular backflow preventer, often a Double Check Valve assembly, is suitable for low-risk situations and protects against backpressure and backsiphonage. However, it does not have a relief valve and may not be as effective in preventing backflow caused by backpressure.

On the other hand, a Reduced Pressure Backflow Preventer (RPZ) is designed for high-risk situations. It has two check valves and a relief valve that opens to the atmosphere, providing an additional layer of protection. This design ensures that even if both check valves fail, the relief valve will open to prevent backflow, making it a more reliable option for protecting water supplies.
