What Is Backflow?

Backflow is an undesirable reversal in the flow of water from your home’s plumbing systems into the clean water supply. In other words, waste that should be carried out through your drains ends up going back into your plumbing and mixing with clean water. 

Backflow can be caused by:

  • Backpressure: This occurs when the downstream pressure is greater than the supply pressure. Issues with your water line or water main could cause this.
  • Back siphonage: This happens when there’s a negative pressure in the supply line. Common causes include high demand placed on the system, like firefighting or heavy water usage during peak times.
  • Cross-connection: A direct link between potable water and a non-potable source can lead to backflow. This could be due to improper plumbing connections.
  • Equipment failure: Failures in mechanisms like pressure relief valves or backflow prevention devices can also lead to backflow.
  • Freezing pipes: In colder climates, freezing can cause pipes to burst, leading to potential backflow situations.

Understanding what causes backflow can help you prevent backflow situations and maintain a clean, healthy, and safe home.

How Do We Prevent Backflow?

At Armstrong Plumbing, we believe prevention is better than a cure, and this certainly applies to backflow incidents. The core of our backflow prevention strategy involves the installation of a device commonly known as a backflow preventer. This device is designed to only allow water to flow in one direction — towards your home, thus preventing any unwanted reversal that could contaminate your water supply.

In addition to installing these devices, we also conduct regular testing and maintenance checks. These tests ensure that the backflow preventer is functioning correctly and that the water supply to your home remains clean and safe. If we find a faulty device during our inspections, our skilled professionals will replace it promptly, minimizing any risk to your water supply. Through these comprehensive measures, we help safeguard your home against backflow issues.

How Often Should Backflow Prevention Systems Be Tested?

Backflow prevention systems should ideally be tested at least once a year. Regular testing is vital to ensure that the device functions effectively and protects your home’s water supply from contamination. Additional testing may be required if your plumbing has recently undergone some major repairs or if your water usage patterns have significantly changed. It’s always a good idea to consult a plumbing professional to determine the ideal testing schedule for your specific circumstances.

Is Regular Backflow Testing Required in Missouri?

Yes, regular backflow testing is required by law for properties in the state of Missouri. According to the state’s Department of Natural Resources, backflow prevention devices must be tested at least annually by a certified backflow prevention assembly tester. This regulation is in place to ensure the safety and cleanliness of the public water supply.

However, the state does acknowledge that some plumbing systems should be checked more often than others, and individual counties and municipalities may have their own backflow testing requirements. That’s why you should always work with a certified backflow testing team like Armstrong Plumbing to work out a testing schedule tailored to your unique needs.

Common Answers To Your Questions

Have questions? We are here to help. Still have questions or can't find the answer you need? Give us a call at 636-538-5179 today!

  • How do I know if I need to replace a main water line?

    This is usually a matter of age and condition. If the pipes in your home are older than 50 years or so, you should be checking them regularly for signs of rust or corrosion. Corroded water lines need to be replaced right away.

  • What can I do about a leaky faucet?

    Often, a leaky faucet is caused by a corroded O-ring, gasket, or valve seal. Try shutting off the water and removing the faucet handle. You may be able to fix the problem by tightening the nut that holds all the internal parts in place. You may also want to try disassembling the faucet to inspect its components. If you notice a part that is broken, replacing that part can do the trick. If you continue having problems with a dripping faucet, give us a call.

  • Is there a way to prevent clogged drains in my house?

    Yes! First of all, don't put things down your drains that don't belong there: this includes hair, oil or grease, coffee grounds, hard food and egg shells. A drain stopper or filter can also stop larger materials from going down your drain and clogging it.
