Journeyman Plumber ExamPlumbing Code and RegulationsMedium
A client is requesting a new high-efficiency condensing boiler installation in their commercial building. The plumber must ensure proper disposal of the condensate, which is acidic. According to plumbing codes, what is the most common and required method for treating or neutralizing acidic condensate before it enters the building's drainage system?
- ACollection in a sealed container for periodic hazardous waste disposal.
- BDirect discharge into a municipal storm sewer.
- CDilution with potable water at the point of discharge.
- DDischarge into an approved condensate neutralization device.
Show answer & explanationAnswer & explanation
Correct answer: D. Discharge into an approved condensate neutralization device.
Acidic condensate from high-efficiency appliances must be neutralized before being discharged into the drainage system to prevent corrosion of pipes and environmental harm. An approved condensate neutralization device is the standard and required solution.
Why the other options are wrong
- A. Collection for hazardous waste disposal is impractical and not the standard method for continuous condensate discharge from boilers.
- B. Discharging acidic condensate into a storm sewer is prohibited due to environmental regulations and potential harm to infrastructure.
- C. Dilution alone is often insufficient and not an approved method for consistent neutralization, nor is it explicitly permitted by code.
Condensate Neutralization
The process of raising the pH of acidic condensate, typically from high-efficiency heating appliances, before it is discharged into the building's drainage system.
- Protects drainage pipes from corrosion.
- Prevents environmental harm.
- Achieved using a neutralization device containing limestone or marble chips.
