Understanding Backflow and Backflow Prevention Devices

Backflow Prevention 101 

A lot of cost and energy goes into treating freshwater resources to ensure it is safe for drinking and daily use. First, the water must be chemically treated to remove pathogens. After the water is safe, it is transported through a vast network of piping before it arrives at homes. Once the water reaches the house, it still has to be safe to drink, and it must remain so as long as it sits in the pipe. 

Even in small towns, the journey that water can take before it comes out of the tap can be through miles of pipes. At every point of use along the way, there is a possible point of failure where contamination can happen that can ruin the water for everyone down the chain. Various devices exist to protect treated water from contamination, but most people are unaware of the ones in their own plumbing systems. Here is a quick article about backflow, backflow preventers that protect treated water from contamination, and the importance of regular backflow testing. 

Backflow 

While plumbing systems are designed to reduce the chances of problems, backflow is a fairly common threat to the water supply when not prevented. When the flow of water increases in the system, the larger lines can pull water backward through smaller pipes in an action similar to siphoning. When these smaller pipes are in contact with chemicals or contaminated water, this can be a big problem, allowing pollutants into clean water supplies. 

Backflow has been documented in a number of settings and has exposed people to harmful pollutants like medical waste, sewage, and dangerous chemicals. When backflow occurs, the only thing that can be done is to flush the system until the threat no longer remains. In some cases, this has taken millions of gallons of water to flush contaminants out of the system. 

How Is Backflow Prevented? 

Backflow prevention devices and methods are used to prevent backflow and water contamination. These can range from small attachments on hose bibs or large pipe fittings on irrigation equipment to air gaps in the system. When these devices are correctly installed and the methods properly implemented, they act as a check valve, only allowing water to flow in one direction. 

Small backflow preventers are also known as vacuum breakers because they allow air to be sucked into lines under backflow conditions instead of polluted water. These devices are recommended for use on hose bibs outdoors. Larger devices also may be required by certain municipalities to prevent backflow.

How Often Is Backflow Testing Needed? 

If there is any doubt about the presence or requirement of backflow preventers on a property, it is always best to consult a professional. Professional plumbers can offer invaluable advice to protect the water supply. Plumbers also perform backflow testing when it is required. 

Most municipalities require backflow preventers to be tested annually and certified. A plumber will be able to check that they are working, so they can continue protecting water from backflow. This ensures they are always ready and functioning correctly to protect public health.
