NASSCO Online Certification
Why Get NASSCO-Certified?
For more than 20 years, NASSCO has helped set the standard for the proper assessment of mainline pipes through its Pipeline Assessment Certification Program, PACP™. Building on those established standards, NASSCO now certifies plumbers, drain cleaners, sewer camera professionals, and small contractors in the proper assessment and cleaning of building sewers and drains.
NASSCO is also marketing certified professionals to private property owners, realtors, and home inspectors — helping create more demand for qualified pros who can inspect and clean building sewers and drains before costly repair decisions are made.
Course Options
NASSCO offers BSDI™, Drain Cleaning, or both certifications together for professionals working with building sewers and drains.
The BSDI™ course is a self-paced online course that takes approximately 1.5 hours to complete and covers the general approach to inspection, how to complete the BSDI inspection report, and assessment codes and associated requirements for a proper BSDI inspection.
