A. Scope. The provisions of this Chapter shall govern the general regulations not specific to other Chapters.

B. Basic Principles . The basic principles of this Subsection are enunciated below as basic goals in environmental sanitation worthy of accomplishment through properly designed, acceptably installed and adequately maintained plumbing systems. Some of the details of plumbing construction must vary, but the basic sanitary and safety principles are the same. The principles may serve to define the intent of this Part and other applicable Parts of the Louisiana State Sanitary Code (LAC 51).

1. Principle Number 1. Buildings, structures and premises intended for human habitation, occupancy, use of employment, or the preparation or processing of food, drinks or other materials for human consumption shall be provided with an adequate, safe and potable water supply through a safe system of piping to all fixtures, appliances, appurtenances, etc.

2. Principle Number 2. Every building having plumbing fixtures installed and intended for human habitation, occupancy or use on premises abutting on a street, alley or easement in which there is a community sewerage system shall have a separate connection with the sewer main.

3. Principle Number 3. A dwelling type building provided with a drainage system, a community sewerage system connection or an individual sewerage system shall have at least one water closet, one bathtub or shower, one lavatory, one kitchen-type sink and an adequate source of hot water for each family unit to meet minimum basic requirements for health, sanitation and personal hygiene. Water heating facilities shall be accessible for emergency maintenance without entering any individual apartment or living unit, except that water heaters may be located within an apartment or living unit when supplying hot water to that unit only. All other buildings, structures or premises intended for human occupancy or use shall be provided with adequate sanitary facilities as may be required, but not less than one water closet and one lavatory.

4. Principle Number 4. Plumbing fixtures shall be made of smooth nonabsorbent material, shall be free from concealed fouling surfaces, and shall be located in ventilated enclosures.

5. Principle Number 5. Each fixture directly connected to the sanitary drainage system shall be equipped with a water-seal trap.

6. Principle Number 6. No substance which will clog the pipes, produce explosive mixtures, destroy the pipes or their joints or interfere unduly with the sewage disposal process shall be allowed to enter the building drainage system.

7. Principle Number 7. Proper protection shall be provided to prevent contamination of food, water, sterile goods and similar materials by backflow of sewage. When necessary, the fixture, device or appliance should be connected indirectly with the building drainage system.

8. Principle Number 8. No water closet shall be located in a room or compartment which is not properly lighted and ventilated.

9. Principle Number 9. If water closets or other plumbing fixtures are installed in buildings where there is no sewer within a reasonable distance, suitable provision shall be made for disposing of the building sewage by some accepted method of sewage treatment and disposal.

10. Principle Number 10. Where a plumbing drainage system may be subject to backflow of sewage, suitable provisions shall be made to prevent its overflow in the building.

11. Principle Number 11. Plumbing shall be installed with due regard to preservation of the strength of structural members and prevention of damage to walls and other surfaces through fixture usage.

12. Principle Number 12. Sewage or other waste, from a plumbing system, which may be deleterious to surface or subsurface waters shall not be discharged into the ground or into any waterway unless it has first been rendered innocuous through subjection to some acceptable form of treatment.

13. Principle Number 13. Plumbing fixtures, devices, appliances and appurtenances shall be adequately supplied with water in sufficient volume and pressure to enable them to function properly.

14. Principle Number 14. The pipes conveying water to plumbing fixtures, appliances, devices and appurtenances shall be of sufficient size as to supply water at rates that will prevent undue pressure drops at any one fixture, when any other fixture, appliance, device or appurtenance or group is being flushed, operated or used.

15. Principle Number 15. There shall be no direct or indirect cross connections, either existing or potential, between a safe potable water supply and an unsafe, nonpotable supply.

16. Principle Number 16. Adequate protection shall be provided to prevent possible backflow or back-siphonage of an unsafe or potentially hazardous fluid or material into a safe water supply.

17. Principle Number 17. Piping and connections of the plumbing system shall be of durable materials, free from defects in workmanship and materials, and systems shall be designed and constructed to provide adequate service for a reasonable life under stresses imposed by structural loading, temperature variation, vibration and other conditions.

18. Principle Number 18. Devices for heating and storing water shall be designed and installed to prevent all danger from overheating and explosion and to prevent undue flow of hot water or steam into the cold water supply pipes.

19. Principle Number 19. Refrigerators, coolers, receptacles, sterilizers, vats and similar equipment used for storing or holding foods, beverages, sterile goods and water conditioning equipment, etc., shall discharge into the building drainage system through an indirect waste.

20. Principle Number 20. Water closets, bathtubs, showers, urinals and similar fixtures shall be suitably enclosed and screened for privacy.

21. Principle Number 21. Plumbing systems, including fixtures, shall be maintained in sanitary condition and proper working order.

22. Principle Number 22. Sewage and wastes from plumbing and drainage systems shall be adequately treated and disposed of in accordance with the requirements of the plumbing official.

23. Principle Number 23. No potable water, soil or waste pipe shall be installed or permitted outside of a building, or concealed in outside walls or in any place where they may be subjected to freezing temperatures, unless adequate provision is made to protect them from freezing.

C. Repairs and Alterations. In existing buildings or premises in which plumbing installations are to be altered, repaired, or renovated, necessary deviations from the provisions of this Part may be permitted, provided such deviations conform to the intent of this Part and are approved in writing by the plumbing official.

E. Workmanship. Workmanship shall conform to generally accepted good practice.

F. Rodent-Proofing. All exterior openings provided for the passage of piping shall be properly sealed with snugly fitting collars of metal or other approved rodent-proof material securely fastened into place. (Also, additional/more specific requirements which may be applicable can be found at LAC 51:V.305.F, LAC 51:V.305.J, and LAC 51:V.307.C.)
