ATTRIBUTION:

Functional Statement:

F81

To minimize the risk of malfunction, interference, damage, tampering, lack of use or misuse.

F40

To limit the level of contaminants.

Objective:

OH1.1

 

APPLICATION:

Depth, design and sealing of traps, in plumbing systems in buildings.

INTENT:

To limit the probability that inertia of the water flow [pressure differential] and evaporation, or malfunction of mechanical devices, will lead to the failure of trap seals, which could lead to the leakage of sewer gases into the building, which could lead to a negative effect on indoor air quality, which could lead to harm to persons.
To limit the probability that leakage from the failure of trap seals will not be identified and corrected, which could lead to the leakage of sewer gases into the building, which could lead to a negative effect on indoor air quality, which could lead to harm to persons.
