Certified plumbing inspectors ensure and maintain the safety of our water supply. Hamilton County Public Health inspects backflow devices, water heaters, and new and remodeled plumbing installations. When complaints about incorrectly installed plumbing or permit compliance arise, inspectors investigate and work to remedy problems.
