What Is Backflow and Why Does It Matter?

Backflow is the unwanted reversal of water flow within a plumbing system, causing potentially contaminated water to flow back into your clean water supply. This can happen due to changes in pressure, either from back siphonage or back pressure, and often introduces pollutants such as:

• Fertilizers and pesticides from irrigation systems
• Industrial fluids or chemicals
• Bacteria and waste from sewer systems
• Dirty water from hoses or submerged fixtures

Even a minor backflow event can cause serious health risks. That’s why local plumbing codes in Alexandria—and throughout Virginia—require the installation and regular testing of approved backflow prevention devices, especially in commercial properties, apartment complexes, and homes with irrigation systems or fire sprinklers.

How Backflow Prevention Works

A backflow prevention device is a mechanical assembly or air gap installed within your plumbing system to ensure that water flows in one direction only—into your property, not out of it. These devices are designed to shut off or block contaminated water when reverse flow occurs.

There are several types of backflow prevention assemblies, including:

• Pressure Vacuum Breakers (PVBs)
• Double Check Valve Assemblies (DCVAs)
• Reduced Pressure Zone Devices (RPZs)
• Atmospheric Vacuum Breakers (AVBs)

The type of device required depends on your plumbing system, the level of hazard, and local code requirements. At Cherry Blossom Plumbing, we assess your specific needs and install the right device for maximum protection and compliance.

Common Causes of Backflow Problems

Backflow issues typically stem from pressure imbalances in your plumbing system. Understanding the common causes can help you spot problems early and prevent costly repairs or contamination:

• Main water line breaks or repairs in your area
• High water usage or pressure drops in your building.
• Faulty or outdated backflow prevention devices
• Irrigation system malfunctions
• Cross-connections with non-potable water sources
• Fire hydrant use near your property

If left unchecked, these conditions can compromise your water quality and even lead to code violations. That’s why regular maintenance, inspection, and testing of your backflow prevention system is essential.

Warning Signs of a Failing Backflow Device

A failing backflow device may not always show obvious signs, but these common symptoms could indicate trouble:

• A noticeable drop in water pressure
• Discolored or foul-smelling water
• Water leaks near the device or cross-connection
• Sounds of gurgling, bubbling, or hissing in the plumbing system
• Standing water near irrigation systems or utility meters
