Pipe Leak in Glendale

During an inspection of the plumbing system in a basement-level structure in Glendale, significant deterioration was identified in the cast iron drain infrastructure. The main drain lines, marked as NEWAC 4″X10′ HUBLESS PIPE (ASTM A888 CISPI 301 UPC), showed extensive corrosion and rust consistent with decades of service. White mineral deposits and scaling covered the pipe exteriors, and the concrete ceiling displayed water staining and efflorescence patterns—clear indicators of active moisture issues and aging infrastructure.

The system also included galvanized steel supply lines running parallel to the drain lines, along with PVC elbow fittings and connectors at various diameter transitions. Metal strapping bands and hangers secured the pipes to the concrete structure, but inspection revealed the original supports were worn and inadequate for the system’s condition.

To address the leak, the team reinforced the pipe support system by installing new fabric strapping bands and metal hangers, securing all lines—both drain and supply—to the ceiling structure with proper spacing and alignment. This work stabilized the corroded cast iron pipes and galvanized lines, reducing stress on compromised sections and preventing further deterioration. The newly installed strapping was wrapped with clean material, providing both structural support and protection from environmental exposure.

The reinforced piping system is now properly secured and stable. Given the age and condition of the cast iron and galvanized components, monitoring for future corrosion and considering a long-term pipe replacement plan is recommended.
