How To Prevent Backflow In Residential Areas

‘Backflow’, as the name suggests is not healthy for you and your plumbing system. Your residential plumbing system is structured in a way that wastewater stays away from your potable water. The clean water enters your home through municipal water pipelines while dirty water takes exit from your home through Municipal sewer lines. So basically, backflow is a situation when filthy water flows in the wrong direction, flows backwards into clean water lines, and enters your home plumbing systems. For instance, a toilet is overflowing and backing up with dirty water instead of flushing out through sewage lines. Let's get aware of the kinds of backflow issues and their prevention. These two kinds of backflow problems are back siphonage backflow and back pressure backflow.

What is Backpressure backflow?

When the pressure of non-potable water is greater than the pressure of the main water, backpressure backflow occurs. This downfall in potable water pressure can occur due to line flushing, breakage in the main water line, or elevation differences. This situation might arise due to high booster pumps, which create downstream pressure or high temperature or heat expansion from boilers.

What is Back-Siphonage backflow?

This type of backflow occurs due to negative pressure in the waterline that means the pressure in the supply line falls below the atmospheric pressure. This leads to a reversal of non-potable water into a clean water supply. The differential pressure and cross-connection creates a link between the clean water and the dirty water source. Likewise, backwater backflow can cause due to construction activities, breakage in the main water supply, or firefighting activities.

Threats of backflow

A backflow problem contaminates the clean water by mixing the clean water with filthy water. Potable water is essential for the survival of life around us.

  • Air gaps
    This is a common practice to maintain the pressure in the plumbing system to avoid backflow.Where there is no scope of air gap their backflow preventer is to be installed.
