Plumbing 101: Understanding Backflow Prevention

A lot of things can happen in the plumbing system if not maintained properly. Aside from burst pipes and low water pressure, backflow can occur. If the pressure is reduced greatly, liquid gets back to the potable supply, which gets contact with contaminated water from the ground. To prevent health issues, make sure to work with the experts.

Why does it happen?

There are two main reasons why backflow happens. First is the back pressure, which happens when there’s a high compression but less than supply. Then there’s the back siphonage, which is the result of the low supply.

If the supply is interrupted, back siphonage can happen. But when the heating system at home became unvented, back pressure occurs. In this case, there must be a consistent pressure on the plumbing system to avoid these problems.

How to prevent it?     

To prevent a reversed flow of water, there are devices that can be used at home:

  • Hose bib – It’s a product that protects the single outlet in case pressure drops. This device has a spring and valve, which closes and opens as compression change.
  • Vacuum breakers – This material can be installed in pipes to regulate the movement of water. The device senses a sudden drop in air pressure, leading to backflow. If that happens, a check valve closes to prevent the reverse of liquid.
  • Individual protection – Any point of contamination in the property can be regulated by this device. This way, filtered water is safe from the contaminated one.

The best way to stop this issue from happening is to call the plumbers for help. They can reassess the situation and find the best device that can be installed in the plumbing system. Once these devices are installed, annual maintenance must be done.
