Okla. Stat. tit. 19, § 19-863.40

All plumbing materials, equipment and methods of installation

thereof in every county subject to the provisions of this act shall

be in strict conformity with approved standards for health and

safety to persons and property. Compliance with the plumbing code

as said code exists at the date of passage of this act of any city

having a population of from one hundred and eighty thousand

(180,000) to two hundred and forty thousand (240,000) according to

the last Federal Decennial Census located in any county as defined

herein shall be deemed to be prima facie evidence of compliance with

this act.

The board of county commissioners of any county within the

provisions of this act are hereby authorized to create, by

resolution duly adopted, the office of plumbing inspector for such

county. Such inspector shall be a person who holds a certificate of

master plumber under the provisions of the laws of this state,

relating to cities of two thousand (2,000) or more inhabitants, and

shall have had at least ten (10) years practical experience as a

master plumber. Such plumbing inspector is authorized to inspect

all plumbing installations in any county within the provisions of

this act, to determine that the same are done within the provisions

of this act. However, where any such plumbing installations are

subject to inspection by the duly qualified, appointed and acting

plumbing inspector of any city or town, having a system of water

supply or sewerage by reason of contract with the owner or builder

of such plumbing facilities or otherwise, approval by such municipal

plumbing inspector shall be deemed to establish compliance with this

act and inspection by the county plumbing inspector or county

plumbing permits will be unnecessary.

The board of county commissioners may, on recommendation of the

county plumbing inspector, adopt all necessary rules and regulations

to carry out purposes of this act and may prescribe the necessary

permits, notices and inspection procedure and set and determine the

fees therefor. Such fees shall be reasonable and shall be

sufficient to meet the expenses of operation of the office of county

plumbing inspector. The county commissioner shall be authorized to

hire such deputy plumbing inspectors for such terms and at such

compensation as they may deem reasonable. The county plumbing

inspector shall issue, without examination, certificates of

competency to all persons holding such a certificate issued by any

city or town in the State of Oklahoma of two thousand (2,000) or

more inhabitants, provided that such certificate has been issued or

renewed for the year in which application therefor to the county

plumbing inspector is made.
