Commercial Backflow Testing in Cleveland: Who Needs It and How Often
If you own or manage a commercial building on Cleveland Water, a letter about your backflow test shows up every year. Here's what the requirement is, why it exists, and where owners get stuck, especially when a test fails or a device has to be moved or replaced.
This is general information based on Cleveland Water's published backflow policies and Ohio's backflow rules. Your water supplier's requirements for your specific connection always control.
The Short Answer
Who: Every commercial water service connection on Cleveland Water needs a backflow prevention device. Some residential connections do too.
How often: The device is tested when it's installed, when it's repaired, and every year.
By whom: A tester with a valid State of Ohio certificate of competence.
Reporting: Results are submitted online to Backflow Solutions Inc. (BSI), the company Cleveland Water uses to track backflow data.
If results aren't submitted: Water service may be interrupted.
What Backflow Is and Why the Water Department Cares
Cleveland Water explains backflow as a pressure change that reverses the normal direction of flow. If that reversal happens at an unprotected cross-connection, it can pull contaminated water back into the drinking water supply. Examples include a boiler, an irrigation line, a fire sprinkler system, or process equipment. A backflow preventer keeps water moving one way. Cleveland Water says it requires the devices to comply with Ohio EPA regulations, which are in Ohio Administrative Code Chapter 3745-95.
Who Needs a Backflow Preventer
According to Cleveland Water's backflow prevention page, devices are required on:
All commercial water service connections
Residential connections with irrigation systems
Residential connections with fire sprinkler systems
Residential connections with swimming pools or hot tubs that have automatic fill valves
Cleveland Water decides the type and location of each device on domestic and fire lines, based on the degree of hazard. Every assembly must be on Cleveland Water's Approved Backflow Device List. If you're applying for new water service and a device is required, Cleveland Water's policies call for a signed, notarized letter of intent stating that one will be installed.
Buildings with an auxiliary water supply, such as a well, cistern, pond or storage tank, have extra steps. The policies call for a private water system survey form. The owner then either disconnects and seals the auxiliary supply under board of health requirements, or keeps it and installs a reduced pressure assembly at the water meter.
How Often Testing Happens
Cleveland Water's program requires a test at installation, after any repair, and once a year. The utility says it notifies customers in writing when a device is due. State rules line up: OAC 3745-95-06 requires inspections and operational tests at installation or repair and at least once every 12 months, at the consumer's expense.
Lawn irrigation is on its own schedule. Cleveland Water requires a pressure vacuum breaker or a reduced pressure assembly on every irrigation system, commercial or residential, with annual testing at start-up in the spring or summer.
How the Annual Test Works, Step by Step
Watch for the notice. Cleveland Water mails it when your device is due. In a multi-tenant building, make sure that mail reaches whoever handles the building, not a tenant's suite.
Hire a qualified tester. The tester must hold a valid State of Ohio certificate of competence to test backflow devices.
Make the device reachable. The tester needs access to the assembly and its test ports, and may need water briefly shut off downstream. Plan the timing with tenants.
The test is performed. Cleveland Water requires current Ohio Department of Commerce procedures, with readings that depend on the device type (double check, reduced pressure, or pressure vacuum breaker).
Results are submitted to BSI. The tester must submit passing results online through BSI Online within a reasonable time.
Keep your own copy. OAC 3745-95-06 says the consumer must keep records of inspections, tests, repairs and overhauls and make them available to the water supplier.
When a Device Fails or Has to Move
Under OAC 3745-95-06, a defective backflow preventer must be repaired, overhauled or replaced at the consumer's expense, and Cleveland Water requires a new test after any repair. Owners are often surprised to learn that the fix isn't always just swapping a part. Cleveland Water's installation rules can turn a replacement into a small plumbing project:
Location. On a domestic line, the assembly goes immediately downstream of the meter or at the first point of entry inside the building.
Fire lines. The assembly goes at the curb stop in a vault or heated enclosure, or at the first point of entry. If the curb stop is 50 feet or more from the point of entry, the device belongs in an underground vault or an above-ground heated enclosure at the curb stop.
Reduced pressure assemblies. These must be above ground and protected from freezing. State rules also say they may not sit below ground in a pit or vault, and their relief port discharge has to be visible, with adequate drainage.
Indoor clearances. Indoors, the assembly should sit 12 to 30 inches above the finished floor, at least 12 inches from the nearest wall, with 24 inches of clearance in front. Side-mounted test ports must face into the room, and the area must be free of noxious fumes.
No unprotected bypass. A bypass line needs equal protection.
Inspection. Cleveland Water inspects the installation after it's connected.
A device squeezed into a corner, mounted at ceiling height, or sitting where a reduced pressure assembly has nowhere to drain may need to be relocated, not just replaced. That is plumbing work: new piping, possibly a floor drain, and coordination with the water shutoff.
Pitfalls We See Owners Run Into
The notice goes to the wrong person. Tenants, previous owners or old management companies get the letter, and the deadline passes.
The test was done but never reported. Cleveland Water goes by what's in BSI. Ask for confirmation that the results were submitted.
Irrigation is forgotten. A separate irrigation device has its own spring start-up test.
Build-outs add hazards. A new restaurant kitchen, a car wash bay or a sprinkler upgrade can change the degree of hazard. That can change the device Cleveland Water requires. See restaurant and commercial kitchen plumbing.
Freeze damage. Devices in unheated spaces, and irrigation devices left charged into winter, can crack.
Does This Apply Outside the City of Cleveland?
Cleveland Water serves many communities beyond the city. If your bill comes from Cleveland Water, its backflow program applies. If your water bill comes from another utility or from your city, ask that supplier about its backflow program. The state rules in OAC 3745-95 apply to public water systems across Ohio, but local procedures and reporting differ.
Where ACC Solutions Fits
ACC Solutions coordinates commercial plumbing in the Cleveland area, including the work that often follows a backflow test: replacing a failed assembly, relocating one that doesn't meet clearance or location rules, adding drainage for a reduced pressure assembly, and installing new devices during build-outs and service upgrades. ACC partners with several plumbing companies and coordinates the work, so you have one point of contact. Plumbing is quoted after a walkthrough, because the device's location, the piping around it, and the water shutoff all change the job.
