What is a cross connection? A guide to plumbing cross connections from inspectapedia.com
Introduction
When it comes to plumbing, cross-connections can be a significant concern for both residential and commercial properties. A cross-connection occurs when the water supply for a clean water system comes into contact with contaminated water. This situation can cause serious health hazards for people who consume the contaminated water. In this article, we'll explore what a cross-connection is, how it can occur and how to prevent it.
What is a Cross-Connection?
A cross-connection is a connection between two water systems, where one system is for potable water, and the other system is for non-potable water. When these two systems connect, it can lead to contamination of the potable water system. For example, if the pipe carrying non-potable water is connected to a pipe carrying potable water, there is a risk of contamination.
How Does a Cross-Connection Occur?
Cross-connections can occur in a variety of ways. One of the most common ways is through a garden hose. If a garden hose is left lying in contaminated water, and the other end is connected to a potable water source, there is a risk of cross-connection. Similarly, if a hose is used to siphon gasoline, and the other end is connected to a potable water source, it can create a cross-connection.
The Dangers of Cross-Connection
Cross-connections can cause serious health hazards for people who consume the contaminated water. Contaminated water can contain harmful bacteria, viruses, and chemicals that can cause illness and even death. Therefore, it is essential to prevent cross-connections to ensure the safety of potable water.
Preventing Cross-Connections
To prevent cross-connections, it is important to install backflow preventers. A backflow preventer is a mechanical device that prevents the backflow of contaminated water into the potable water system. There are different types of backflow preventers, including air gaps, double-check valves, and reduced pressure zone devices. It is important to choose the right type of backflow preventer based on the specific needs of your property.
Testing and Maintenance
It is not enough to install backflow preventers; they also need to be tested and maintained regularly. Backflow preventers can fail due to wear and tear, so it is important to have them tested by a licensed plumber at least once a year. Regular maintenance can help to ensure that the backflow preventers are working correctly and protect the potable water system from contamination.
Conclusion
In conclusion, cross-connections can be a serious concern for both residential and commercial properties. They can lead to contamination of the potable water system, which can cause serious health hazards. Therefore, it is important to install backflow preventers, test them regularly, and maintain them to prevent cross-connections. By taking these measures, we can ensure the safety of our potable water system and protect the health of our communities.
