Backflow - what is it?

1. What is a Backflow Prevention Assembly Test?

A backflow prevention assembly is a critical device designed to safeguard potable water systems from contamination caused by the reversal of water flow, known as backflow. Backflow can occur when pressure changes cause non-potable water or harmful substances to flow back into the drinking water supply.

There are two primary mechanisms to prevent backflow:

• Air Gaps: These eliminate cross-connections by creating a physical barrier.

• Mechanical Backflow Preventers: These devices act as barriers within the plumbing system, stopping backflow from occurring.

Testing ensures your backflow prevention assembly is functioning properly and effectively protecting your water system.

2. Why is Backflow Testing Important?

Backflow testing protects your water system from contaminants such as:

• Septic Systems: Preventing waste from entering the water supply.

• Irrigation Systems: Keeping fertilizers, pesticides, and pet waste out of your home’s drinking water.

By maintaining and testing your backflow assembly, you ensure the safety of your property and the community’s water supply.

3. Why Do I Need to Test My Backflow Device, and How Often?

Backflow prevention assemblies, like any mechanical equipment, can wear out over time. Regular testing is required to ensure they remain effective and compliant with safety regulations.

In Texas, the Texas Commission on Environmental Quality (TCEQ) mandates annual testing for backflow prevention devices or after repairs or re-piping have been completed. This testing is essential to maintain the integrity of public drinking water systems.

4. What Happens If My Test Fails?

If your assembly fails during our testing, we will provide you with a detailed estimate for the necessary repairs. If your city or water department conducts the testing and you receive a failed test notice, simply forward the notice to us. We’ll assess the issue, provide an estimate, and schedule the repair upon approval. Once completed, we will submit the repair report for you.
