Why Annual Backflow Testing Is So Important

Although they can be prevented, backflow incidents still occur throughout the state. These incidents can lead to water contamination in municipal water supplies, boil water advisory, and other problems. It is mandatory to conduct bi-annual backflow testing legally. Local business owners may be wondering why or if they are required to conduct these tests. This guide will answer all of your questions about backflow testing.

What is Backflow Testing? Is it Required in Florida?

Florida’s building codes require that all residential and commercial irrigation systems be equipped with backflow prevention systems. This requirement was established in 1990. To prevent contamination of the public water supply, the state requires bi-annual testing. Licensed plumbers are able to perform backflow testing that meets state requirements. 

How Does a Backflow Preventer Works?

Water flows in one direction when Florida’s plumbing systems are working properly. Drain lines, for example, carry waste water away from homes and businesses. And then water supply lines bring fresh water into buildings. Backflow is when water flows in the opposite direction. It is a problem due to the possibility of water contamination. Backflow prevention devices can reduce the risk of exposure to polluted water. Backflow preventers are entranceways that connect Florida’s water system to municipal pipes. They allow potable water to enter while keeping the city’s wastewater out. Contact us today to arrange a visit from one of our certified plumbers. 

What Is Backflow?

Florida homeowners usually call plumbers to fix problems like drain and sewer clogs. These issues can be very serious but they are often not as severe as the backflow challenges. These incidents are not often discussed but they are quite common. The water supply can be affected by chemicals and wastewater. This could lead to burns on the skin, as well as respiratory problems. You can find one million microorganisms in a single milliliter of sewage. This makes it a reason to have your plumbing system tested regularly by a Florida plumber.

Backflow Prevention Testing

Backflow prevention devices last approximately 40 years. Although this sounds incredible, it is important that you remember that these systems are complex. The backflow valve structure is more durable than the springs, screws, seals and bolts. They will eventually wear out over time. This leads you to wonder “How can I tell if my backflow stopper is failing?” A malfunction in a backflow valve structure could lead to the total failure of your commercial plumbing system. In severe cases, the system may not work at all. Regular backflow testing is crucial because of the potential problems. A Florida plumber will be able to check for signs of premature wear by performing these tests. They will then perform repairs and backflow replacement to prevent the devices from bursting. You can reduce water contamination by having a bi-annual backflow prevention testing. These vital inspections prevent wastewater from entering the municipal water supply and ensure that public water is safe and clean. 

Most Common Backflow Problems

Backflow prevention systems usually include two check valves. A catastrophic backflow can occur if both valves fail. The first valve opens at a particular water pressure. This is typically 2 PSI. It may also open at a lower pressure if there is a problem. This valve prevents back pressure-related backflow. Water may pass through this valve if it fails. Backflow preventers can also fail due to an open point that is too high or too low. Both of these issues can adversely affect the assembly’s performance. Our qualified plumbers can service and replace these systems, which reduces the risk of water contamination.

Common Problems With Backflow Prevention Assemblies

It is vital to perform backflow testing. This allows professionals to identify any potential problems with the backflow preventer assembly. The following are some of the most common issues that can cause your backflow preventer failure:

  • Faulty first valve. Reduced pressure backup preventer’s first check valve opens at specific water pressures. This allows the water to pressurize the area between the first and the second check valves. It opens at a minimum of 2.0 PSI. However, if it is damaged, it may open at lower pressures which could affect its performance.
  • A second check valve is not working properly. We use backflow testing for the second check valve. This involves inspecting the direction of water flow. It can fail if water leaks through it and back into the area between the checks.
  • The relief valve opening point is too high. Water enters the relief valve through a sensing line. This causes it to reach an elastic element. It builds up pressure, compressing a spring. The spring then moves the relief valve disc, which blocks the seal. Backflow preventers have different minimum thresholds in terms of PSI. The pressure can rise if one of the internal components, the relief valve disc, fails to embed properly.
  • Too low relief valve opening point. Sometimes the relief valve opening point is too low. This usually happens because of something that restricts movement into relief valve stem mechanism. Scale and corrosion are common causes.
