Intent

Intent 1:

To limit the probability that:

  • inadequate airtightness will lead to leakage, or
  • inadequate venting will lead to the buildup of sewer gases within tanks or sumps, which could lead to back pressure, which could lead to resistance to flow.

This is to limit the probability of the entry of sewer gases into occupied space, which could lead to negative effects on indoor air quality, which could lead to harm to persons.
