Understanding Backflow

Backflow happens when water flows backward in your pipes, going in the opposite direction of where it’s supposed to go. This can lead to contaminated water, which is not suitable for drinking or other uses. The potentially germ laden water will get into our clean water supply. Nobody wants to drink, bathe, or wash dishes with dirty or unsafe water!

What is Backflow Testing?

Backflow testing is like a safety check for your water supply. It helps ensure that the water flowing into your home or building stays clean and safe to use. Sometimes backflow can be checked by a simple visual inspection. Some backflow prevention devices are more complex and require the precision of specialized tools.

In any case, backflow testing is best done by a professional plumber. Armstrong Plumbing, Air & Electric is a trusted provider of comprehensive plumbing products and services. If Something’s Wrong, Better Call Armstrong!

Why is Backflow Testing Important?

Backflow testing is so important because it helps us make sure our water remains clean and safe. Think of it as a regular check-up for your water supply. If we didn’t test for backflow, we might unknowingly drink or use water that’s been contaminated with harmful substances.

How Does Backflow Testing Work?

During a backflow test, a trained Armstrong plumber checks the backflow preventer, a special device that stops water from flowing backward. The backflow preventer has check valves, which are like one-way doors for water. They let water flow in one direction but stop it from going back the other way.

The Testing Process

Here’s a simplified version of the backflow testing process:

  1. Shutting Off the Water: First, the water supply to the building or property is shut off temporarily.
  2. Inspecting the Backflow Preventer: The technician inspects the backflow preventer to make sure it’s in good working condition.
  3. Testing the Check Valves: The check valves inside the backflow preventer are tested to ensure they’re doing their job correctly.
  4. Checking for Leaks: The technician looks for any leaks or issues in the system that might lead to backflow.
  5. Recording the Results: The results of the test are documented to confirm that the backflow preventer is functioning correctly.

Why Do We Need Backflow Prevention?

Backflow prevention is essential for a couple of reasons:

  1. Protecting Drinking Water: Backflow prevention ensures that the water we use for drinking, cooking, and bathing remains clean and safe.
  2. Preserving Fire Protection Systems: In places like schools, hospitals, and businesses, backflow prevention is crucial to keep fire sprinkler systems working properly. These systems rely on clean water to protect us in case of a fire.

Types of Backflow Prevention

There are different types of backflow preventers, each designed for specific purposes. Some common types include:

  1. Double Check Valve Assembly: This type is often used in homes and small businesses.
  2. Reduced Pressure Zone Device: It’s used in places where the risk of backflow is higher, like hospitals and factories.
  3. Pressure Vacuum Breaker: You might find these in outdoor irrigation systems to prevent backflow into the water supply.

Why Annual Testing Matters

Backflow preventers need to be tested regularly, usually once a year, to make sure they are still doing their job. This ensures that our water remains safe year-round.
