Under normal conditions, water flows from the public main into your building. Under certain conditions, such as a main break or a sudden drop in supply pressure, water can reverse direction and flow back into the supply. If that water has been in contact with irrigation systems, boilers, fire sprinklers, chemical dispensers or other equipment, it can carry contaminants into the drinking water system.
Backflow prevention assemblies stop that reverse flow. Because they contain springs, seals and check valves that wear over time, water suppliers typically require them to be tested regularly by a certified tester. We provide backflow testing, repair and documentation for homes and businesses across Goldsby, OK.
How backflow happens
Backflow occurs in two ways. Backsiphonage happens when pressure in the supply line drops below atmospheric pressure, creating a vacuum that draws water backward. Main breaks, heavy water use during firefighting and pump failures can cause this. A garden hose submerged in a bucket of fertilizer during a pressure drop is a classic example of how contaminants can be drawn into household plumbing.
Backpressure occurs when pressure on the building side exceeds supply pressure, pushing water back toward the main. Boilers, pumps, elevated tanks and pressurized systems can create backpressure. Without protection, water from those systems can enter the potable supply.
Cross connections are points where potable water can come into contact with non potable substances. Irrigation systems, fire sprinkler systems, boiler feed lines, commercial dishwashers, chemical injectors and medical or laboratory equipment are common cross connections. Plumbing codes and water supplier rules require appropriate backflow protection at these points.
The level of protection required depends on the hazard. High hazard connections, where contaminants could cause illness or death, require more robust assemblies than low hazard connections, where contaminants might affect taste or appearance but not health.
Types of backflow prevention assemblies
Reduced pressure zone assemblies, often called RP or RPZ assemblies, provide the highest level of protection. They contain two independently acting check valves with a relief valve between them. If either check valve leaks or pressure changes, the relief valve discharges water to atmosphere, preventing backflow. They are used for high hazard applications such as chemical systems, boilers and many commercial connections.
Double check valve assemblies contain two independently acting check valves in series. They protect against both backsiphonage and backpressure for low hazard applications, such as some fire sprinkler systems without additives.
Pressure vacuum breakers protect against backsiphonage only and are commonly used on irrigation systems. They contain a spring loaded check valve and an air inlet valve that opens to break a vacuum. They must be installed above the highest downstream outlet.
Each assembly type has specific test procedures and installation requirements. Testers use calibrated differential pressure gauges to verify that check valves hold tightly and relief or air inlet valves open at the correct pressure.
What happens during a backflow test
Testing follows standardized procedures for each assembly type. The tester connects a calibrated test kit to the assembly's test cocks and temporarily shuts off water to the downstream system, so building occupants should expect a brief interruption.
For a reduced pressure assembly, the tester checks that the relief valve opens at the proper differential pressure, that the first check valve maintains the required pressure difference and that the second check valve holds tight against backpressure. For double check assemblies, each check valve is tested for tightness. For pressure vacuum breakers, the air inlet opening pressure and check valve tightness are verified.
If the assembly passes, the tester records the readings and restores water. If it fails, the tester identifies the likely cause, such as a fouled check valve, worn seals or a damaged relief valve, and provides a price for repair. Many repairs involve cleaning or replacing internal parts using manufacturer repair kits.
After repair, the assembly is retested to confirm it passes. Test results are documented on the forms your water supplier requires and submitted by the deadline, or provided to you for submission, depending on local procedures.
Compliance, deadlines and record keeping
Most water suppliers require annual testing of backflow assemblies, and many require testing after installation, repair or relocation. Notices are typically sent to property owners with a deadline. Missing the deadline can lead to follow up notices, fines or, in some jurisdictions, suspension of water service until compliance is demonstrated.
Testing must be performed by a tester certified according to the requirements of the local water supplier or state program. Test kits must be calibrated at required intervals. We maintain certification and calibration records and provide them when requested.
Keeping records of tests and repairs helps with compliance and budgeting. We provide copies of every test report and can remind you when your next test is due.
For commercial properties with multiple assemblies, we can schedule testing of all assemblies in one visit and provide a consolidated report, minimizing disruption and simplifying record keeping.
Installation requirements and common problems
Backflow assemblies must be installed correctly to function and to be testable. Reduced pressure assemblies need clearance below for the relief valve to discharge without being submerged, and they must not be installed in pits where water can accumulate. Pressure vacuum breakers must be installed above the highest downstream outlet. Assemblies need enough clearance around them for testers to connect gauges and for repairs.
Outdoor assemblies on irrigation systems are exposed to freezing temperatures. Water left inside can freeze and crack the body or damage internal parts. Draining the assembly before winter or installing insulated enclosures prevents this damage. We can help winterize assemblies as part of an end of season service.
Debris from the supply line, such as sand or scale, can lodge in check valves and prevent them from sealing, causing test failures or relief valve discharge. Installing a strainer upstream, where permitted, can reduce this problem. After main breaks or water system work in your area, it is common to see more assemblies fail tests because of debris.
When an assembly is old, has failed repeatedly or parts are no longer available, replacement may be the most practical option. We can replace assemblies with current approved models and perform the required initial test.

Common questions about backflow testing
How often does backflow testing need to be done?
Most water suppliers require annual testing, plus testing after installation, repair or relocation. Your water supplier's notice specifies the requirements and deadline.
Will my water be shut off during testing?
Water to the downstream system is shut off briefly during the test, typically for a short period. We coordinate timing to minimize disruption, especially for businesses.
Why is my backflow preventer leaking?
Reduced pressure assemblies discharge water from the relief valve when a check valve is fouled or worn or when supply pressure fluctuates. Continuous discharge indicates the assembly needs repair.
Do residential properties need backflow testing?
Homes with irrigation systems, fire sprinklers, boilers or other cross connections may have backflow assemblies that require testing. Requirements vary by water supplier.
What happens if my assembly fails?
The tester explains the likely cause and provides a price for repair. After repair, the assembly is retested. Results are reported to meet your supplier's requirements.
