Freezing temperatures, hard water buildup, or debris can all damage or affect a backflow preventer from sealing properly. Once properly installed, backflow repair parts will keep your backflow preventer in working order—and protect your drinking water from potentially toxic pollutants being siphoned into your water supply. Shop PVB replacement parts as well as Y-strainers, test cocks, ball valve replacement parts and any other parts for your RPZ and DCA devices.

Even the best backflow devices reaching a breaking point. From a cracked PVB pipe to general wear and tear, there are several factors that go into system failure. The objective is to keep your system ticking as long as possible by making smart choices, whether it’s choosing brass backflow replacement parts over plastic or taking proper measures to prevent backflow device freeze damage.

Now that we've identified the causes, let's get to some solutions. Tap the PLAY button and watch Sultan of Sprinklers, Dwayne Smith, show you what to do when your system breaks down.
Reduced Pressure Zone Assemblies (RPZ): These provide advanced protection for large, complex plumbing systems by using a series of check valves and relief valves.
Double Check Assemblies (DCA): These backflows are relatively simple in design, and are the most common type of backflow preventer for underground or in-line installations.
Inspect your backflow preventers annually to ensure they’re functioning properly. Consider hiring a certified backflow tester, especially for complex RPZ systems. In colder climates, ensure that backflow preventers are properly drained or insulated to prevent freezing damage. If the backflow preventer ever starts to leak, shut off the valve immediately.
How can I tell if my backflow preventer is not working?
Signs of a failing backflow preventer include water leaking from the relief valve, fluctuating water pressure, unusual noises, or visible damage. Consider preemptively ordering sprinkler backflow preventer parts or a repair kit to make changes before they cause water contamination.
What causes a backflow preventer to fail?
Like any mechanical device, backflow preventers wear out over time. Common causes of damage include worn seals, mineral buildup, corrosion, or freezing. High water pressure and debris in the water can also damage internal components, leading to failure. Lack of regular maintenance and testing can speed up this wear.
