Backflow Testing & Certification
For backflow prevention, testing is essential and required by Illinois EPA regulations.
Backflow testing, inspection and certification
The fact that clean water flows throughout your building’s commercial plumbing system is sometimes taken for granted. Fortunately, your plumbing system was designed to protect your water from pollutants and contaminants using backflow preventers. Organizations like the EPA also help to protect building occupants from unforeseen emergencies.
The EPA requires backflow prevention devices to be installed on all domestic water supplies, fire protection water supplies, lawn irrigation system lines and the like. Those backflow valves or assemblies must be tested every year to ensure they are working as designed. The design allows water to flow in one direction but never in the opposite direction to prevent drinking water from becoming contaminated by stagnant water. Backflow prevention, simply put, prevents contaminated water from flowing back into clean water supplies.
What We Do
Backflow Testing & Certification
The EPA requires that all backflows be certified by a Cross-Connection Control Device Inspector (CCCDI) licensed plumbers one time per year. At Valley Fire Protection, our CCCDI licensed plumbers will test and certify backflow devices and submit all required reports to the appropriate municipality on your behalf.
- Inspection of cross-connection control device
- Repair backflow assemblies
- Installation of reduced pressure zones (RPZs) and backflow prevention devices
- Testing and certification of new and existing backflow devices
- Submit all required reports to local municipalities
- Contact you annually to schedule testing
Cross-connection control and backflow prevention
Drinking water piping is run throughout your building; where it connects to various plumbing fixtures, a cross-connection exists. Drinking water contamination occurs if and when a contaminant is introduced to one of those plumbing fixtures and it flows back (backflow) into your clean water system. But if your domestic water system is fitted with backflow prevention devices, they will protect the integrity of your system and your drinking water.
Cross-connections can occur in places like a faucet, washroom, garden hose or dishwasher. If a faucet, for example, is situated lower than the top of a bathtub or laundry tub, and the tub is filled with water containing cleaning chemicals, the clean water supply would immediately be contaminated. There are dozens of contaminants like bacteria, waste, pesticides, metals, and toxins, that can be introduced into a system. The solution in this case would be to raise the faucet higher so that it’s situated above the lip of the tub, which creates an air gap between the faucet and contaminated liquid.
Another example of how cross-contamination occurs would be if the end of a garden hose was placed into a pail of dirty water, allowing the dirty water to flow back into the clean water supply. Backflow preventers like vacuum breakers are placed on hose bibs to prevent this type of contamination from occurring.
Backflow also occurs when the pressure in the water delivery main is lower than it is supposed to be. Should there be a ruptured main, back-siphonage can occur, which is also a form of backflow.
Finally, backflow can occur when a water pump gets cross-connected with the internal plumbing system. Since the EPA requires annual backflow device certification by a CCCDI-licenced plumber, your building and its occupants should always be in good hands. Backflow preventers, when installed correctly and well maintained, can keep that consistent, clean flow of water going in the right direction.
- Backflow preventers on fire protection systems Because there are cross-connections on fire protection systems, they must be properly protected, which is why backflow prevention devices, must be installed, inspected and maintained.
- Ensuring you have backflow protection for your commercial plumbing system Only certified backflow inspectors are qualified to ensure that your commercial property has the protections necessary to prevent backflow contamination. They know what to look for, they know when action needs to be taken and they can give commercial property owners the assurances they need to remain confident that their water will remain uncontaminated, regardless of what’s gone wrong with the plumbing system, inside or in the main lines from the municipality.
For backflow testing, inspection and certification, contact Valley Fire Protection. Our certified, licensed professionals can inspect your entire plumbing system.
Backflow prevention services for commercial irrigation systems
Because many commercial irrigation systems are tied to potable water lines, reduced pressure zone (RPZ) valves need to be installed to protect against back siphonage.
- Conducting annual RPZ backflow testing To ensure that your commercial irrigation system is up to code, a certified contractor must conduct an annual RPZ backflow test.
- RPZ inspection Valley Fire plumbers have years of experience inspecting RPZ valves, which means they know exactly what to look for as they go over your commercial irrigation system’s RPZ protections.
- Backflow certification Certification is mandatory, but Valley Fire handles the paperwork for the client and ensures that the local municipality gets the documentation they need, keeping the client up to code.
- Backflow preventer installation Our services make it easy and pain free for our clients, including with the installation of backflow prevention solutions.
- Backflow preventer repair and replacement Like any mechanical device, the mechanical parts in a backflow prevention system will wear down over time, so after several years a backflow prevention device may require minor repairs or replacement. Valley’s plumbing vehicles and shop are equipped with replacement parts from a range of manufacturers, so repairs are done quickly and with little to no disruption to your business operations.
Our client references testify to our high- quality approach to what we do, whether it’s performing an annual RPZ inspection or installation, maintaining, repairing or replacing any portion of a commercial plumbing system. Our customer-centric approach is second to none.

RPZ backflow certification
Building owners pay for dozens of property upgrades and upkeep services every year, but backflow service protects the health and safety of every tenant so it may just conceivably be the most important expense.
Annual RPZ backflow certification protects your employees and clients from coming into contact with contaminated water. It’s so important that Illinois requires that your RPZ backflow assemblies be certified, which is a service we provide at Valley Fire Protection. By some estimates, roughly five percent of backflow prevention devices are currently experiencing issues that could lead to failure, which is a good reason to keep our number handy and to keep your system in check with regular testing.

Types of backflow preventers
Backflow preventers come in many different shapes and sizes and are built to protect against very specific situations. Some are only installed in systems where the hazard threat is considered low, while others are only used in high-hazard situations. The following is a list of some of the most common preventers in use in commercial properties today.
- Reduced pressure zone (RPZ) One of the most reliable and effective backflow preventers, often placed in food and beverage processing plants, chemical refineries and other facilities where backflow could lead to contact with highly toxic material.
- Pressure vacuum breaker (PVB)Most often associated with irrigation and sprinkler systems, PVBs are very common units almost always installed right after the isolation valve.
- Double check valve assembly (DCA) Steam generators, heating equipment and swimming pools are mostly considered “medium hazard situations,” requiring the installation of a DCA.
- Double check detector assembly (DCDA) The DCDA is used in continuous and non-continuous pressure applications. It is installed in low-hazard situations, such as fire sprinkler systems and to the system supply main to detect leaks and unauthorized use of water.
- Atmospheric vacuum breaker (AVB) Lab sinks, commercial laundry and lawn sprinklers are often the go-to systems for AVBs. However, they aren’t designed to protect against back pressure or continuous pressure, but they are used in low and high hazard situations.
- Spill-resistant vacuum breaker (SVB) Almost always used in indoor installations, the SVB is similar to a pressure vacuum breaker, but is less apt to discharge upon filling. It’s designed to be used for applications where there is constant pressure.
- Reduced pressure principle assembly (RP) An RP has two independently acting approved check valves that are hydraulically operated. It’s for continuous and non-continuous pressure applications and prevents back-siphonage and back-pressure conditions.
- Reduced pressure principle detector assembly (RPDA) This is a line-sized approved backflow assembly that has a bypass water meter and a reduced pressure principle backflow prevention assembly. It provides back-siphonage and back-pressure protection and can be used in low and high hazard situations.
A single commercial property might be equipped with several different types of backflow preventers; each requires the expertise of a certified and licensed plumber to install, repair or certify. Fortunately, the plumbing professionals at Valley Fire Protection have experience with all types of backflow preventers.
