OH2 Sanitation



Intent 1:

To exempt certain fixture drains from the requirement for an indirect connection in Subclauses and, and to permit direct connection to pipes that:

  • are terminated to form an air break above the flood level rim of fixtures that are directly connected to sanitary drainage systems, and
  • are extended through roofs when fixtures on 3 or more storeys are connected to them.

This is to limit the probability of backflow protection, which could lead to sewage contamination of food preparation fixtures or sterilization devices, which could lead to unsanitary conditions, which could lead to harm to persons.
