Fire Service Mains
& Water Tanks License
Ohio's Fire Service Mains and Water Tanks License is among the most demanding credentials in the plumbing trade. Pipe Doctor's licensed specialists install and service the underground water supply infrastructure that feeds fire suppression systems — work where precision and code compliance are non-negotiable.

Install, test, and maintain fire hydrants, post indicator valves, OS&Y gate valves, and other control valves on fire service water supply systems.
Install and service above-ground and underground fire water storage tanks, including fill lines, suction connections, overflow piping, and level controls.

Conduct hydrant flow tests, system pressure tests, and acceptance testing to verify fire water supply meets the design demand for the protected facility.
