Each dwelling unit should have at least one water closet, a kitchen sink, a lavatory, and either a bathtub or shower to meet basic sanitation and hygiene requirements.
Plumbing fixtures should be made of smooth, non-absorbent material, free from concealed fouling surfaces and located in ventilated enclosures.
The drainage system should be designed, constructed, and maintained to safeguard against fouling, deposit of solids, clogging, and with adequate cleanouts for easy cleaning.
All piping should be made of durable, approved materials, free from defective workmanship.
Each fixture directly connected to the drainage system should be equipped with a water-sealed trap.
The drainage pipe system should be designed to provide adequate air circulation.
Vent terminals should extend to the outer air and be installed to prevent clogging and the return of foul air to the building.
Plumbing systems should be tested to identify any leaks or defects.
Substance that could clog pipes or damage components should not be allowed to enter the building drainage system.
