Improper Installation Results in Corroded Gas Line and Gas Release in Residence

Location: Terrace

Regulated industry sector: Gas

Incident overview

A high-efficiency furnace in a home discharged corrosive condensate directly onto a black iron gas pipe due to an improperly installed drain. This led to pipe corrosion and an uncontrolled release of natural gas. Gas concentrations reached dangerous levels before the issue was reported by a postal worker and mitigated by a gas utility technician. The incident was attributed to installation errors in the condensate drainage system.
