Plumbing Inspection

The duties of the Plumbing Inspection Division of the Warren County Health District include plan review for new plumbing in commercial and residential buildings, inspection of the plumbing work through all phases of construction, and final approval of the plumbing work prior to occupancy.

The Plumbing Inspection Division is responsible for protecting the water supply by ensuring, through plan review and inspections, that the plumbing has no cross-connections or possibility of backflow. The plumbing inspectors are also responsible for ensuring the waste plumbing is properly vented and trapped so the plumbing safely carries waste away while causing no health problems.

The Warren County Health District employs five State of Ohio Certified Plumbing Inspectors. By law, only State Certified Plumbing Inspectors can inspect plumbing work. The plumbing inspectors are responsible for plan review and inspection of all residential commercial plumbing work whether it is a remodel or new construction in Warren County.

In addition, to the aforementioned duties, the five plumbing inspectors provide technical consulting services to homeowners installing their own plumbing. They also work closely with the Environmental Health Division on plumbing related problems in restaurants and grocery stores.

Permit Applications

WCHD has transitioned over to iWorQ for all Plumbing Permits and Registration. All forms must be submitted in to the iWorQ Portal and proper payment be made to ensure all applications are processed in a timely fashion. When filling out your permit application and/or homeowner’s permits, please fill in ALL information.

Backflow Devices

Warren County Health District has contracted with Backflow Solutions, Inc., also known as BSI Online, to assist with State required cross-connection/backflow tracking regulations. BSI Online has partnered with over 550 water purveyors to develop and manage effective cross-connection control programs to help protect all our water resources. BSI helps water purveyors by sending notifications, assists with customer service inquiries, and manages required data on behalf of Warren County Health District.  BSI Online will serve as the primary point of contact for the program and can be contacted below:

A backflow prevention device is used to protect water supplies from contamination caused by a backflow situation which may be caused by a loss of water pressure.

In municipal water supply systems, water is normally maintained at a significant pressure to enable water to flow to and out of the plumbing fixtures in your home or business. When the pressure drops for some reason such as may occur when the fire department connects to a fire hydrant to fight a fire or a water main breaks or some other situation happens, contaminated water may be drawn into the system. To prevent such an occurrence, there needs to be some type of backflow prevention method utilized. The best and safest type of backflow prevention is an air gap ( a physical separation between the water outlet and the rim of the fixture). If an air gap is not possible, then the proper backflow prevention device is required. This backflow device is considered a “containment” backflow preventer and is regulated by the Ohio Environmental Protection Agency and your water supplier.

Section 312.10 of the Ohio Plumbing Code covers the installation, repairs and testing of isolation backflow preventers (BFP) and Section 608 of the Ohio Plumbing Code addresses protection of the potable water supply within a building these devices are known as “isolation” BFP. Again, the best type of backflow prevention is an air gap, such as the outlet of a faucet and where water would flow over the rim of a sink or bathtub. The Warren County Plumbing Department checks to ensure there is an air gap, if there is no way to provide one, then we check to see that the proper BFP device is installed. These BFP’s, if testable,  are required to be tested (by a certified backflow preventer tester) upon installation and at least every twelve months thereafter.

The simplest and most effective way to provide backflow prevention is to provide an air gap. An air gap is simply a space between any device that opens to a plumbing system (like a valve or faucet) and any place where water can collect or pool. Some cities and municipalities do their own testing of backflow devices for their area. Please contact the appropriate office with any questions or concerns you may have for testing your device:
