Question 71

Condensate drain piping from a condensing boiler should NOT be allowed to discharge onto a street or an alley.

Discharging condensate drain piping from a condensing boiler onto a street or an alley is inappropriate due to potential environmental hazards and regulatory compliance issues. Such discharge can lead to slippery surfaces and contribute to drainage problems in public areas.

A) onto a street or an alley

This option is correct because discharging condensate onto streets or alleys can create safety hazards such as slippery conditions for pedestrians and vehicles. Additionally, it may violate local plumbing codes or environmental regulations aimed at preventing pollution and ensuring public safety.

B) onto a flat roof

Discharging onto a flat roof is generally acceptable as long as the roof is designed to handle such drainage and there is proper drainage to prevent water accumulation. This option does not pose the same public safety risks as discharging onto streets or alleys.

C) into a French drain

Discharging into a French drain is permitted, provided that the French drain is appropriate for handling condensate. This method can effectively manage excess water and prevent pooling, making it a suitable option compared to discharging onto public walkways.

D) to a grassy area

Discharging to a grassy area can be acceptable if the area is designed to absorb and manage water effectively. Unlike streets and alleys, grassy areas can help mitigate potential runoff issues and are less likely to create hazardous conditions.

Conclusion

The correct answer is option A, as discharging condensate onto streets or alleys poses significant safety and environmental concerns. The other options either contain acceptable practices or do not present similar risks, highlighting the importance of appropriate discharge methods for condensate drain piping from condensing boilers.
