Plumbing shall be designed and adjusted to use the MINIMUM QUANTITY OF WATER consistent with proper performance & cleaning3
Devices for heating and storing water shall be so designed and installed as to prevent dangers from EXPLOSION through overheating.4
Every building having plumbing fixtures installed and intended for human habitation, occupancy or use on premises abutting(adjacent to) a street, alley or easement where there is a PUBLIC SEWER, shall be connected to the

Plumbing fixtures shall be made of SMOOTH NON-ABSORBENT MATERIAL, free from concealed fouling surfaces and Shall be located in ventilated enclosures7
The drainage system shall be designed, constructed and maintained to safeguard against fouling , deposit of solids,
clogging and with adequate CLEANOUTS so arranged that the pipes may be readily cleaned8
All pipings of plumbing systems shall be of durable NAMPAP APPROVED materials,

STRUCTURAL MEMBERS and the prevention of damage to walls and other surfaces through fixture usage21
Sewage or other waste from a plumbing system which may be deleterious (harmful/ toxic)to surface or sub -surface waters shall not be discharged into the ground or into any waterway, unless first RENDERED INNOCUOUS through
