Why Your Home Needs A Yearly Backflow Test

Your home needs an adequate amount of pressure so that the water does not flow back into the water system and cause contamination. To make sure that this doesn't happen and cause major health problems, you may want to perform a backflow test to protect the purity of your water.

How Water Pressure Works

Water reaches your home and can defy gravity to supply your upstairs bathroom thanks to water pressure. Many homeowners simply assume that the city will always provide enough pressure for water to flow through the pipes without an issue.

However, the city sometimes needs to use water pressure for another purpose such as putting a fire out. When this happens, you may face the issue of backflow. This can lead to contaminants making their way into your water supply such as pesticides and fertilizer. You might also have excessive bacteria enter your water supply.

Problems That Cause Low Water Pressure

If you discover that there is a problem with your water pressure, this can be a result of a problem within your own home. For example, you may have a water leak that could lead to a drop in the water pressure of your home. You will need to identify the cause of the low water pressure so that you can bring it under control. However, there are some cases where there is nothing that can be done about your falling water pressure. For example, uneven water use in your neighborhood can lead to water pressure issues.

The Importance of Backflow Testing

To keep water from flowing back into the water supply, each structure has a backflow device. This device needs to be tested every year to make sure that it is functioning properly. Because governments typically do not inform citizens of the need to perform a backflow test, the responsibility rests in the hands of the citizens. You will want to have your backflow prevention tested at least once a year by a certified backflow testing agency. 

Backflow Prevention

When a drop in your water pressure occurs, an RPZ valve opens up and dumps excess water out. This prevents contaminated water from making you sick. Another way to prevent backflow is to use an air gap. This creates a space where contaminated water can pool. Fortunately, once professionals have performed a backflow test, you can be more confident that your water will be safe to drink.
