What Backflow Actually Is (And Why It Matters)

Backflow is when contaminated water flows the wrong way into your home’s clean water supply. Normally, water flows in one direction—from the public supply into your home. But when that flow is interrupted, it can reverse and suck in dirty water from other sources.

There are two main ways this happens:

• Backpressure, when a building’s internal water pressure exceeds the pressure from the main supply
• Backsiphonage, often caused by a sudden drop in water pressure (like when a water main breaks or a fire hydrant opens)
  

Either scenario can pull polluted water from places like your garden hose, sprinkler system, or even a boiler right into the drinking water line.

Common Ways Backflow Happens in Homes

Here are a few everyday situations that can create a backflow risk in your home:

• Sudden pressure drops in the municipal water system: When a water main breaks or a fire hydrant is opened nearby, the sudden loss of pressure can cause dirty water to be sucked back into clean supply lines.
  
• Hoses submerged in buckets, pools, or ponds: If you leave a hose sitting in contaminated water, and the pressure drops, that dirty water can siphon back into your drinking water supply.
  
• Improperly installed irrigation or sprinkler systems: Without proper backflow prevention, lawn chemicals, fertilizers, and stagnant water can flow back through sprinkler heads into your home’s plumbing.
  
• Cross-connections between potable and non-potable water lines: These are direct links between clean and dirty water systems. A bad plumbing connection can let contaminants into your drinking water without you even realizing it.
  
• Faulty boiler or HVAC systems: Heating and cooling systems that are not properly protected can also cause backflow, introducing chemicals like antifreeze or rust into your home’s water lines.
  

Why Backflow in Summerville, SC is an Issue

For homeowners in Summerville, backflow isn’t just a hypothetical concern—it’s a real issue.

Health risks are real

Backflow can bring in pesticides, bacteria, and other contaminants that don’t belong in your drinking water. This is a direct risk to your health and your family’s.

Local laws require prevention

The Summerville Commissioners of Public Works (CPW) and the South Carolina Department of Health and Environmental Control (SCDHEC) require certain properties to have backflow prevention devices installed and tested annually. If you have an irrigation system, for example, you may be required to get it tested by a certified plumber.

It affects the environment too

Contaminated water doesn’t just stay in your pipes—it can seep into local water sources and affect wildlife, soil, and nearby ecosystems.

What You Can Do to Prevent Backflow

If you’re feeling overwhelmed, don’t worry. Here are a few simple, smart ways to protect your home:

Install backflow prevention devices

• Use hose bibb vacuum breakers on outdoor faucets
• Make sure your sprinkler system has a proper backflow preventer
• Consider a pressure vacuum breaker (PVB) or reduced pressure zone (RPZ) device for added protection

Keep your air gaps intact

An “air gap” is just what it sounds like—a bit of space between a faucet or fixture and any water that could get sucked back in. For example, make sure the end of your kitchen faucet doesn’t dip below the flood level of the sink.

Get regular plumbing checkups

A licensed plumber can spot issues you wouldn’t know to look for. Preventative plumbing inspections are especially important if your home has older pipes or irrigation systems.

Winterize outdoor systems

Frozen water can expand and crack backflow prevention devices. Make sure to drain and shut off outdoor plumbing lines before the first freeze each year.

Educate everyone in the house

Even something as innocent as leaving a hose in a muddy bucket can create a backflow risk. If everyone in your household knows the basics, it makes a difference.

How to Spot a Possible Backflow Problem

It’s not always obvious when backflow happens, but here are some common warning signs:

• Water that looks cloudy, dirty, or discolored
• A bad taste or smell in the water
• Visible debris or particles coming from the tap
• An unexplained drop in water pressure
  

If you notice any of these, stop using the water and call a plumber right away. Until you get the all-clear, avoid drinking, cooking with, or bathing in the water.
