Proper irrigation and water management in both residential and commercial properties have become more crucial than ever. Homeowners and businesses alike face the challenge of ensuring their water systems function effectively and safely, all while adhering to local plumbing codes. One essential component that often flies under the radar is the vacuum breaker, particularly when it comes to hose bibs. This article delves into the importance of installing a vacuum breaker on a hose bib, how it works, the potential hazards of neglecting this device, and much more.
What is a Vacuum Breaker?
A vacuum breaker is a plumbing device designed to prevent backflow in a water system, effectively protecting the potable water supply from contamination. By allowing air to enter the water system when there is a drop in pressure, a vacuum breaker ensures that water does not siphon back into the supply lines.
How Does a Vacuum Breaker Work?
When water is being drawn from a hose bib, a vacuum can occasionally form if there is a sudden stop in water flow or a significant drop in pressure. In such situations, the vacuum breaker allows air to enter the system, breaking the vacuum and preventing any contaminated water from being pulled back into the main line. This function is essential for protecting the purity of drinking water and keeping a safe environment for both humans and pets.
Types of Vacuum Breakers
There are typically two main types of vacuum breakers used in residential and commercial applications:
- Atmospheric Vacuum Breaker (AVB):
This simple device is installed above the highest point of the water outlet. It relies on gravity to function and requires a vertical installation to ensure reliability.
Pressure Vacuum Breaker (PVB):
- Unlike the AVB, the PVB can be installed at or below the highest outlet point. It includes a spring-loaded check valve that provides added resistance to backflow. This option is often preferred for hose bib applications as it can better withstand variations in pressure.
