Frequently Asked Questions

A backflow assembly, also known as a backflow prevention device or backflow preventer, is a critical component in plumbing systems designed to protect potable (drinkable) water supplies from contamination due to the reversal of water flow. Backflow can occur when the pressure in a plumbing system changes, causing non-potable water (water that is not safe for consumption) to flow backward into the clean, potable water supply.

Backflow assemblies are particularly important in situations where there is a risk of cross-connections between potable water and non-potable water sources. Cross-connections are points in plumbing systems where non-potable water could potentially come into contact with or mix with clean drinking water. Backflow prevention devices help ensure that this cross-contamination does not occur.

There are different types of backflow assemblies designed for various levels of protection, and they are often required by plumbing codes and regulations. Some common types of backflow assemblies include:

1. Pressure Vacuum Breaker (PVB): This is a mechanical device that creates an air gap to prevent backflow. It is commonly used in irrigation systems and outdoor plumbing connections.
2. Double Check Valve Assembly (DCVA): This assembly consists of two check valves separated by a chamber. It provides a higher level of protection and is often used in commercial and industrial settings.
3. Reduced Pressure Zone Device (RPZ): An RPZ assembly includes two check valves and a relief valve. It provides the highest level of protection and is used in critical applications, such as fire sprinkler systems.
4. Air Gap: While not a physical assembly, an air gap is a simple and effective method of preventing backflow by maintaining a physical separation between potable water and non-potable water sources.

Backflow assemblies are installed at specific points in plumbing systems where there is a risk of backflow occurring. They require regular testing, maintenance, and sometimes repair to ensure their proper functioning. Properly functioning backflow assemblies are essential for maintaining the safety and quality of the water supply, preventing the contamination of drinking water, and adhering to plumbing codes and regulations.

4. Insurance Requirements: Some insurance policies require businesses and properties to have their backflow assemblies regularly tested and maintained as part of risk management measures.
5. Liability Reduction: Ensuring that your backflow prevention devices are in working order reduces the risk of potential legal liabilities resulting from water contamination incidents.
6. Property Protection: Backflow incidents can damage plumbing systems and property infrastructure. Regular testing helps prevent costly repairs and property damage.
7. System Efficiency: A malfunctioning backflow assembly can disrupt water flow and pressure within your plumbing system. Regular testing helps maintain efficient water distribution throughout your property.
8. Peace of Mind: Knowing that your backflow prevention devices are regularly tested and properly maintained gives you peace of mind that your water supply is safe for consumption and other uses.
9. Environmental Stewardship: By preventing the contamination of water sources, you contribute to the protection of the environment and natural resources.
10. Public Trust: Businesses and properties that prioritize water safety through regular backflow testing demonstrate their commitment to public health and safety.

Overall, regular backflow assembly testing is a proactive measure that helps ensure the safety and quality of your water supply, protects your property and infrastructure, and demonstrates your compliance with regulations and best practices. It's an investment in the well-being of your community and the environment.

A backflow test is a comprehensive procedure conducted to assess the functionality and effectiveness of a backflow prevention assembly or device. The primary goal of the test is to ensure that the backflow prevention device is working correctly to prevent the reverse flow of water and potential contamination of the clean water supply. The test is typically performed by certified technicians who have expertise in backflow prevention systems. Here's an overview of what a backflow test generally consists of:

1. Initial Inspection: The technician visually inspects the backflow prevention assembly to ensure that it is properly installed, correctly oriented, and free from any visible damage or defects.
2. Shut-Off Valve Check: The technician confirms that the shut-off valves before and after the backflow prevention assembly are in the correct position for testing.
3. Pressure Differential Test: Using specialized equipment, the technician measures the pressure differentials across the backflow prevention device. This involves measuring the pressure on both the inlet and outlet sides of the assembly.
4. Check Valve Operation: The technician checks the operation of the check valves within the assembly. These valves should allow water to flow in one direction and prevent reverse flow.
5. Relief Valve Operation (If Applicable): For some types of backflow assemblies, a relief valve is present. The technician checks its operation to ensure that it functions properly.
6. Seal Testing: The technician checks the sealing mechanisms of the assembly to verify that they are working as intended. This helps prevent leakage.
7. Flow Testing: In some cases, the technician may perform a flow test to determine the flow rate of water through the assembly. This is especially important for assemblies used in high-demand situations, such as fire protection systems.
8. Documentation: Throughout the test, the technician records measurements, observations, and any findings related to the assembly's operation and condition.
9. Reporting: After completing the test, the technician generates a detailed report that includes the test results, observations, and any recommendations for repairs or maintenance.
10. Regulatory Compliance: The test report is often submitted to relevant authorities or regulatory agencies to demonstrate compliance with testing requirements.

It's important to note that the specific steps and procedures involved in a backflow test may vary depending on the type of backflow prevention device, the local regulations, and the testing equipment used. Professional technicians who are certified in backflow prevention testing are trained to perform accurate and thorough tests to ensure the safety and integrity of the water supply.

The cost of a backflow test can vary widely based on several factors. These factors can include the location, the type of backflow prevention device being tested, local market conditions, the complexity of the testing process, and the qualifications of the testing technician. Here at Ability Backflow we believe in upfront pricing. Our Commercial rate starts at $125 and our residential customers can expect to pay around $95 for their testing.
