FAQs
Is BSDI accepted in my state?
BSDI condition codes are based on PACP®, which 900+ U.S. municipalities already require for public mains. Many private-lateral programs accept BSDI reports today. Check the map inside the course portal.
Do I need PACP before BSDI?
No. BSDI is designed for plumbers who may have never taken a NASSCO course.
What equipment do I need?
Any push camera with on-screen footage timestamp. We cover optimization tips inside Module 2.
How long before I can advertise the certification?
Immediately after you pass the exam you’ll receive a digital badge, printable certificate and your directory listing goes live within 24 hours.
