What You Need to Know about Backflow Prevention

Backflow prevention is a necessary part of both residential and commercial plumbing systems. The purpose of a backflow preventer is to stop the bacteria and other contaminants in the wastewater side of the plumbing system from entering into the freshwater side and polluting it. A backflow prevention device makes certain that sewage can only flow one way through the plumbing system; a valve closes to prevent wastewater from rising the wrong direction when there is a change in pressure from either the freshwater or wastewater sides.

Here are few things you should know about backflow prevention in your home.

First, you probably already have a backflow preventer in place

A backflow prevention device is legally required to be installed in a home’s plumbing system; this is an issue of public health. However, you may at some point need to have your current device replaced, and only a licensed technician can do this.

Second, influences outside your control can cause backflow

When backflow occurs, it is rarely because of something that you did in your home. The cause of backflow is an abrupt shift in pressure: a loss of pressure on the freshwater side, or an increase in pressure on the wastewater side. This can happen because of problems in the municipal sewer system or a huge drain on freshwater because of the fire department. You can’t control these occurrences, so you must rely on a working backflow preventer to keep your water safe from contamination.

Third, you should have your backflow preventer tested annually

Many Central Florida municipalities require annual testing of a home’s backflow preventer. Only specially certified technicians can provide this test to determine if the backflow preventer is working correctly or if it needs repairs or a replacement. Schedule whatever work you need done as soon as possible from licensed plumbers.
