What You Should Know About Backflow Prevention March 16, 2020

What You Should Know About Backflow Prevention, St. Paul, Minnesota

Some properties need backflow prevention devices for their plumbing systems. These pieces of equipment keep sewage and irrigation runoff from backwashing into your supply, but if they aren’t maintained properly, they could fail. That’s why it’s important to have them tested by a plumber. The guide below explains how backflow happens and why routine testing matters. 

What Is Backflow?

Back siphonage occurs when water flow is reversed—that is, if wastewater that should be flowing into a sewer instead comes back up your pipes. This can happen for many reasons. For example, a broken water main can cause an imbalance of pressure in the pipes that, in turn, alters the direction of fluid movement. 

This is inconvenient, messy, and potentially dangerous. Wastewater may contain contaminants like bacteria and chemicals like herbicides absorbed from soil. 

Why Should a Plumber Test Your Backflow Preventers?

By allowing water to only flow one way, this system prevents cross-contamination. However, like any piece of plumbing, a backflow preventer will begin to wear over time, and eventually may fail if not properly maintained. 

To reduce the risk to your property, have a licensed and certified plumber inspect any such devices at least once annually as required by law and repair or replace them as needed. Owners of rental properties must have similar inspections performed to protect their tenants.
