Radiant helps homeowners protect their irrigation and water systems with properly installed and maintained pressure vacuum breakers.
Pressure vacuum breakers play a key role in protecting your irrigation system and home’s water supply from contamination. When installed incorrectly or left unmaintained, they can fail to prevent backflow, putting your water at risk. Radiant’s licensed plumbers ensure your PVB is installed at the proper height, tested for performance, and maintained to meet code requirements. Whether you’re installing a new system or addressing a failing device, we make sure your backflow protection works reliably when it matters most.

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.
Yes—we do that every day. Whether your pressure vacuum breaker is leaking, cracked, or just outdated, Radiant Plumbing & Air Conditioning offers fast, professional replacement services. 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.
