State backflow resource
Ohio backflow certification requirements
Ohio cross-connection control is addressed in Ohio Administrative Code Chapter 3745-95 for public water systems, while backflow technician qualification is handled through Ohio building-standards rules. Candidates should check both the water-supplier side and the technician-certification side.
Certification authority
Ohio EPA and Ohio Department of Commerce, Board of Building Standards
Backflow certification can involve state drinking-water rules, plumbing or building-code rules, health department oversight, and local water supplier acceptance. Confirm the exact path with the official sources below before paying for training or registering for an exam.
What to verify
- Ohio EPA Chapter 3745-95 covers backflow prevention and cross-connection control for public water systems.
- Ohio Administrative Code Chapter 1301:3-7 describes backflow technician certification and examination qualification.
- Water suppliers retain authority over containment-principle backflow preventers required under the cross-connection rules.
Study recommendations
- Study the 3745-95 definitions and where protection is required.
- Review the experience paths for qualifying to sit for a backflow technician examination.
- Expect questions to distinguish water-supplier authority, plumbing/building code authority, and technician certification.
Important local-program note
A person may complete a training course and still need approval, listing, reporting access, or recognition from a local water supplier or authority. Treat this page as a starting point, then verify the current rule, accepted credentials, forms, and renewal process with the official agency.
