§ 36-25-15.1. Scope and objectives of plumbing standards and rules.

It is the intent of the Legislature that the rules promulgated pursuant to this chapter, in compliance with chapter 1-26, shall include the following requirements and the plumbing commission shall exercise no greater authority than is necessary for the fulfillment of this chapter:

(1)    Plumbing fixtures, devices, and appurtenances shall be supplied with water in sufficient volume and at pressures adequate to enable them to function properly and without undue noise under normal conditions of use;

(2)    Plumbing shall be designed and adjusted to use the minimum quantity of water consistent with proper performance and cleaning;

(3)    Devices for heating and storing water shall be so designed and installed as to guard against dangers from explosion or overheating;

(4)    Drainage systems shall be designed, constructed and maintained to guard against fouling, deposit of solids and clogging, and with adequate clean-outs so arranged that the pipes may be readily cleaned;

(5)    Plumbing materials shall be made of durable, smooth, nonadsorbent and corrosion resistant material, be free from concealed fouling surfaces and shall be free from defective workmanship and so designed and constructed as to give satisfactory service for its reasonable expected life;

(6)    Each fixture directly connected to the drainage system shall be equipped with a liquid seal trap;

(7)    Drainage systems shall be designed to provide an adequate circulation of air in all pipes with no danger of siphonage, aspiration, or forcing of trap seals under conditions of ordinary use;

(8)    Vent terminals shall extend to the outer air and be so installed as to minimize the possibilities of clogging and the return of foul air to the building;

(9)    Plumbing systems shall be subjected to such tests as will effectively disclose all leaks and defects in the work or the material;

(10)    No design for a plumbing system shall permit the entry into the system of any material that will clog or accentuate clogging of pipes, produce explosive mixtures, destroy the pipes or their joints, or interfere unduly with the sewage-disposal process as it enters the building drainage system;

(11)    Proper protection shall be provided to prevent contamination of food, water, sterile goods and similar materials. When necessary, the fixture, device or appliance shall be connected indirectly with the building drainage system;

(12)    Where a plumbing drainage system is subject to backflow of sewage from the public sewer, suitable provision shall be made to prevent its overflow in the building;

(13)    All plumbing fixtures shall be so installed with regard to spacing as to be accessible for their intended use and for cleansing;

(14)    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; and
