What Is Backflow?

Backflow is when water flows the opposite way in a pipeline. This happens in one of two ways:

  1. Backpressure - when the water pressure in your residential plumbing lines exceeds that of the municipal lines
  2. Backsiphonage - a sudden change in water pressure that causes wastewater to flow in reverse

Backflow contaminates your potable water by mixing it with unwanted wastewater. The best way to prevent this is by installing a backflow prevention assembly. Most backflow repair companies offer prevention assemblies and assist with installation. Scheduling backflow repair services to test the quality of your water is another way to protect your potable water supply and plumbing system. Frequently testing potential backflow can prevent future costs associated with significant plumbing issues.

  1. Shut off the main water – This is the first step to ensure safety and prevent others from using contaminated water.

  3. Determine the number of test cocks and bushings needed – Make sure that these materials are clean.
