'Backflow’ is the flow of water in the opposite direction — back into the water supply.

Backflow preventers hold the pressurized fire sprinkler water line from flowing back into the municipal water line — a probable case if there is a loss of pressure from the municipal water line.

Backflow preventers reduce the chances of polluting the municipal water system through cross-contamination.

So, What Actually Is A Backflow Preventer?

A backflow preventer is a mechanism devised to keep water inside a fire protection sprinkler system and other water-based arrangements installed on a property — securing that it solely travels in one direction: from the water main into the pipes of the system.

Approved backflow assemblies have met the requirements of different certified testing agencies and each one is intended for particular applications. The most common assemblies include:

Double Check Valves (DCV)

Specifically outlined to prevent backflow in fire sprinkler systems, DCVs incorporate an inlet (upstream) shutoff valve, two independently operating spring-loaded check valves (usually inside a single valve body), four test cocks, and an outlet (downstream) shutoff valve.

Reduced Pressure Zones (RPZ)

RPZ backflow preventer assembly is most commonly used when hazardous chemicals like antifreeze or corrosion inhibitors are introduced.

RPZs dilate upon the double check valve notion. With a hydraulically operated relief valve that makes them exceptionally dependable, RPZs integrate an inlet shutoff valve, two spring-loaded check valves separated by a pressure differential relief valve, four test cocks, and an outlet shutoff valve.

Reduced Pressure Principle Detector Assembly (RPDA)

Primarily used in fire sprinkler systems, RPDA is a specially designed assembly composed of a line-size approved reduced pressure principle with a specific bypass consisting of a particular water meter.

How Does A Backflow Preventer Work?

 Under normal conditions, the pressure between the two check valves — is sustained at a lower pressure than the supply pressure. If either check valve shall leak — the relief valve is devised to open and discharge water to the outside, ensuring backflow never eventuates.

Please note that RPZ assemblies, while being reliable, encounter much higher pressure and volume loss than double-check assemblies.

Now, inconsistent flow inline pressure (upstream or downstream) will prompt a properly functioning RPZ to periodically release small amounts of water. But during a backflow condition, a large volume of water will flow from the relief valve. And hence, for this reason, RPZ assemblies should not be installed in areas that are subjected to water damage.

Also, it must be noted that both types of backflow preventers scale down the available downstream water pressure.

A proficient contractor must account for this when designing fire sprinkler systems.

Is It Necessary To Have Backflow Preventers In Fire Sprinkler Systems?

Yes. Fire sprinkler systems must have backflow preventers. Municipalities, water purveyors, and plumbing inspectors have outlined, enforced, and set forth plumbing codes and directives for installing backflow preventers so as to protect local drinking supplies. So, please do check and acquire knowledge from your local water authority about the particular requirements for backflow preventers in your area.

Remember: Backflow from fire protection systems can contaminate the potable water. Thus, it is absolutely essential to install backflow preventers in your sprinkler systems. By doing so, you can prevent avoidable accidents — and meet code requirements in the area.

So, ensure to check with your local authority having jurisdiction (AHJ) on the exact backflow prevention requirements in your area, system, and occupancy type.

Let’s Wrap Up:

Thus, if you need to get a backflow preventer installed in your fire sprinkler system or want to get it checked and maintained, be sure to contact Millbrook Fire Protection We can remove or install and double-check and reduce pressure zone backflow prevention assemblies.

It is mandatory for every property owner to install a high-quality backflow device and have a Backflow Testing procedure annually by a certified plumbing company that can perform the backflow test. The test has to be conducted by observing some standard guidelines and to ensure that there should not be any code violations. This short article is all about understanding more about the said test and its importance.

Let's talk backflow prevention. Did you know that only a licensed plumber with a backflow endorsement on that licence can test your backflow device? Did you also know that it is the owner's responsibility to have the backflow device tested annually? Don't worry! We've got you covered! Not only do Gold Coast Plumbing Company's plumbers have the mandatory endorsement to do backflow testing, we also carry the specialised, calibrated instrument required to carry out the test. We will test your backflow device and submit the Form 9 to the City of Gold Coast, and we will send you a copy too!

There is more involved in maintaining a healthy water supply than simply installing a prevention system. Your plumbing and water quality are directly related, so it’s always recommended that you get your plumbing inspected as needed. Learn warning signs that you need backflow testing.

Prevention is better than cure. You’ve probably heard of that a lot of times. I thought it was just for health in general, but recently I found out that it could also apply to plumbing. Yes, you read it right, plumbing. I’m not the type of neighbor who snoops on what’s happening to other people in the community, but this one was definitely something to write about. It just might teach you a lesson or two.

As what I’ve been told, a back-flow prevention device has leaked in one of the areas in the community, an area where establishments were located. So you ask me now, what on earth is that? I actually researched about it, because, like some, I am no star in plumbing. This device acts somewhat as a barrier between the dirty water and the clean water. The dirty water comes from homes and go straight to the sewers while the clean water is actually the water that we drink.

What happens when it gets a leak? The dirty water gets mixed with the clean water. And you could probably imagine how horrible and disgusting that scenario would be. A procedure such as the backflow testing could be done to prevent such scenario. Licensed plumbers do backflow testing to remedy the current situation and make sure it doesn’t happen again. The professional plumbers in Hialeah was luckily easy to contact at that time. The business owners of that establishment were lucky enough that the situation didn’t get worse, or else it would have cost them a hefty fine.
