What Is Backflow?

In layman's terms, backflow is when water reverses its flow and starts to move into areas where it doesn’t belong — back into the clean water system.

To get more specific, backflow happens when low pressure causes water from a potable water system to makes its way back to where it originated. For example, water that has made its way to your irrigation or pool gets pulled back into your water lines. Modern municipal water systems are generally designed to keep the plumbing that provides clean drinking water to your property separated from the plumbing that transports non-potable water with-in your town or cities. When the checks and balances of this system fail, the result is dirty water making its way back through your pipes and into your home or business.

Because of its high risk, backflow is considered to be a public health hazard. Used water can contain all kinds of chemicals, pathogens, and bacteria that are dangerous to human health, therefore it is imperative thatwe do our part to help avoid a back flow situation.

"It is imperative that you immediately seek help from a professional plumbing service when your residence or business is affected by a backflow problem."

What Causes Backflow?

Anywhere sewer pipes and freshwater pipes cross-connect means there is a chance that a backflow incident can have an effect. Normally, these cross-connections are fitted with mechanisms that stop sewage water from contaminating your drinking water, but if a cross-connection is installed incorrectly or at the wrong location in a plumbing system, a backflow incident can overwhelm the mechanisms and allow dirty water to make its way into your home.

In a municipal water supply system, backflow can be caused by a number of issues:

• Flooding
• Broken sewer piping
• Breakdown of devices that regulate water pressure
• Blockages in local irrigation plumbing
• Broken water mains
• Open fire hydrants

In residential plumbing systems, any fluctuation in water pressure can cause dirty water from washing machines, sinks, dishwashers, and pools to contaminate potable water. If your home’s fixtures and plumbing lines aren’t fitted with devices such as hose bibs and air gaps, chances are good that eventually you’ll be the victim of an otherwise easily-preventable localized backflow incident.

How Can Backflow Be Prevented?

To prevent localized backflow accidents, there are several options homeowners and business owners can take:

If you spot any of these signs, contact a plumbing repair service immediately. They’ll investigate any potential problem and implement a proper backflow prevention and mitigation plan if the situation calls for it. Keep in mind that any of the above symptoms could be caused by a plumbing issue unrelated to backflow, but it pays to have an expert check them out anyway — although a clogged pipe won’t cause nearly as much damage as a backflow, you’re better off dealing with any issues now rather than later.

In Case Of A Backflow Problem, What Steps Do You Need To Take?

Taking proper action in the event of a backflow problem is key to minimizing any effects it might have on your property and your health. In the case of a more serious backflow incident caused by acts of nature such as fires, floods, or earthquakes, your local government will most likely have a warning system in place to advise residents on the situation and what steps they should follow. If you suspect your backflow problem is being caused by a municipal outage, stay tuned to a radio or television in order to receive any emergency notifications.

Regardless of the source of the backflow, follow these additional steps:

• Contact a local plumber immediately to get help
• Contact your water utility company to make sure they are aware of the situation
• Avoid bathing or washing with contaminated water
• Avoid drinking any contaminated water.
• If you need to use tap water for any reason, make sure you boil it thoroughly beforehand
• Keep yourself, your family members, and your pets out of areas affected by backflow

A backflow issue is a serious health issue — sewage water is pretty nasty at the best of times, and once it gets out into the open, it can present significant biological hazards to humans, animals, and even property. Not only can potentially deadly diseases be transmitted from backflow water, but toxic chemicals like fertilizers, antifreeze, and copper runoff from poorly-manufactured pipes can be included in contaminated water.
