What is Backflow?

Backflow is when water is pushed in an opposite direction to its intended path. Backflow can be described as a problem. This is more serious than a blocked drain. This means that instead flowing out of your toilet, bathtub and into the sewer system it flows into your plumbing, and out of the toilet, sink, or bathtub drains. The problem could be caused by a number of things.

There are many reasons you may have backflow issues

Broken Backflow Prevention devices: Cross contamination is possible if the backflow preventer in your system is damaged. Modern plumbing fixtures include backflow prevention as an integral part of their design.

Problems with water pressure: A drop in water pressure can lead to cross-contamination between potable and non-potable waters. To prevent backflow (or back siphoning), the pressure must be maintained. This is when water is pulled through the system like a vacuum.

Different types of backflow prevention devices

Certain situations may require that backflow prevention devices be used in plumbing codes. These devices are not required for residential properties, except in cases where there is an irrigation system or large boiler or fire suppression system.

You have a variety of options when it comes to preventing backflow from happening. These devices include:

Air gap: A space between the flood level and water outlet of a plumbing fixture is called an air gap.

Double Check Valve (DCVA) or Double Check Valve Assembly (DCVA). This assembly is made up of two valves that are placed at different points in the plumbing system. This valve works well to prevent backpressure and back siphonage.

A Pressure Vacuum Breaker is a device that prevents non-potable water from contaminating the water source.

The Reduced Pressure Zone Device, also known as RPZD or RPV, is a device that uses two spring-loaded check valves with three vertical testcocks and two shutoffs. These devices can only be installed outdoors if it is above freezing. They can also be used where there is no interruption in meter service. Two backflow prevention devices can be connected in parallel.

How to Test for Backflow Problems

If you don’t feel like hiring a professional to do the job, there are many ways to check your backflow prevention devices. A test kit can be purchased that includes all the necessary tools to perform the test.

No one should be surprised that the first step is to shut off the water. Next, take a look at the device and check to see if it is a reduced pressure device. The device should have information that indicates the flow direction of the water. All the bushings and test cocks that you will need are available. Numinate the test cocks. Switch off the number 2 shutoff valve. Connect the test kit hoses to the test cocks. Now, you can turn the water off.

You will need to turn off the water supply and then run the taps immediately to test the backflow prevention system. You should replace the relief valve if it doesn’t work when water is trying to pass through the system. You should replace the valve assembly if pressure rises.
