What Is Backflow?

Backflow is a term used to describe a situation in which the normal flow of water is reversed in a plumbing system. Backflow is often very dangerous because water that has come into contact with harmful chemicals or pollutants flows back into the drinking water system.

Backflow takes place when pressure within the main water line is lost. Instead of the clean water flowing directly into your home, it flows backward, potentially encountering pesticides, fertilizers, human waste, chlorine, soap, and other harmful contaminants before seeping back into the drinking supply. Backflow often emerges in sinks and bathtubs, and can result in serious illnesses in humans.

What Is Backflow Prevention?

Backflow prevention is the method of stopping backflow from contaminating the public water supply. This method involves installing devices in the cross-sections of your plumbing pipes that are designed to stop water from flowing in the wrong direction. This prevents chemicals, oils, pesticides, and other contaminants from entering your clean water supply in the event that your water line experiences a drop in pressure.

Do I Need a Backflow Preventer?

While anyone who wants to ensure the safety of their drinking water should install a backflow preventer, there are a few situations in which it is extra necessary.

You need to install a backflow preventer if:

  • You have a boiler system
  • You have an irrigation system
  • You use a well
  • You have a swimming pool
  • You have a pond
  • You have a private fire sprinkler system

If you aren’t sure whether or not you need a backflow preventer, reach out to our plumbing specialists. We will inspect your home and offer you our professional advice. We always recommend having a backflow preventer installed anywhere where drinking water might cross-connect with wastewater to ensure your safety.

How Often Should My Backflow Preventer Be Tested?

Just as with any other mechanical device, your backflow preventer needs to be tested by a qualified professional on a regular basis to ensure it is doing its job correctly. You should have your preventer tested at least once a year.

At Carter Services, our plumbing professionals are fully qualified to perform backflow testing. During testing appointments, we turn off your main water supply, examine the preventer, clear out any debris, and run a full safety and performance test. During these appointments, we are able to make sure your preventer is working properly and your clean water supply is protected against backflow.
