ATTRIBUTION:

Functional Statement:

F46

To minimize the risk of contamination of potable water.

F20

To support and withstand expected loads and forces.

Objective:

OH2.2, OH2.3

 

APPLICATION:

Installation of lead waste pipe and fittings, in water systems or building sewers for buildings.

INTENT:

To limit the probability that inappropriate materials will lead to:
  • dissolved lead in water systems, which could lead to contamination of potable water, or
  • an inability to resist the pressure of back filling operations, which could lead to collapse of the pipe, which could lead to sewage backing up.
This is to limit the probability of unsanitary conditions, which could lead to harm to persons.
