A pressure vacuum breaker, or PVB, is a backflow prevention device designed to keep contaminated water from entering your clean water supply. It works by using a spring-loaded check valve and an air inlet valve that open and close based on pressure changes in your system. When pressure drops unexpectedly, the vacuum breaker allows air into the line to prevent dirty water from reversing flow. Radiant Plumbing & Air Conditioning installs and services these devices to help protect plumbing systems that require secure backflow prevention.
A properly installed vacuum breaker should not negatively affect water pressure. However, if your pressure vacuum breaker is leaking or faulty, it may cause a noticeable drop in flow. Our licensed plumbers at Radiant can inspect the unit, identify internal issues, and restore proper pressure with repairs or replacement—whichever solution is best for your system.
Testing a pressure vacuum breaker backflow preventer involves checking both the air inlet and check valves for proper operation, usually with specialized gauges and a test kit. It’s a job that’s best left to trained professionals. Radiant Plumbing & Air Conditioning provides inspection and testing services to ensure your PVB is working as intended and compliant with local plumbing codes.
While it’s technically possible for a homeowner to install a pressure vacuum breaker, backflow prevention devices are regulated for a reason. Proper installation requires correct placement, elevation, and isolation from shutoff valves. At Radiant, we make sure your pressure vacuum breaker installation meets all code requirements and functions as a reliable safeguard for your plumbing system.

Our team will remove the faulty unit, install a new, code-compliant PVB, and make sure your system is leak-free and protected for the long haul.
When it comes to protecting your plumbing system from contamination or pressure issues, the pressure vacuum breaker (PVB) plays a critical role. This often-overlooked device quietly ensures water flows in the right direction—and alerts you when something’s not right. Whether you’re dealing with a leaking pressure vacuum breaker, need a fresh install, or just want to make sure yours is still functioning correctly, Radiant Plumbing & Air Conditioning is your go-to expert.
A pressure vacuum breaker is a compact but powerful valve designed to stop water from flowing backward into your plumbing system. It’s typically installed at outdoor hose connections, wall-mounted fixtures, or exposed lines that are vulnerable to sudden changes in water pressure. While it’s commonly mistaken as something used only in irrigation, the PVB is just as essential in residential plumbing systems that need a high level of control and safety.
These devices respond to pressure changes in your system. If pressure suddenly drops—for instance, during a main line shutdown or after a valve closes too quickly—the PVB allows air into the system, breaking the vacuum and stopping water from reversing direction. The result? Safer, cleaner, and more stable plumbing flow throughout your home or business.
Like any plumbing component, PVBs wear out over time. Exposure to sun, wind, debris, and temperature shifts can all take their toll. Here’s how to know it’s time to call Radiant:
