Subtech Manufacturing Adds Its New Inspector Drain Camera

“The Nick Gromicko model”

TURLOCK, CA. (September 8th, 2020) – Subtech Manufacturing is pleased to announce its newest Sewer Scope Camera for the Home Inspection Industry, the “Nick Gromicko Model”.

Designed and built exclusively for home inspectors in consultation with Nick Gromicko.

Home Inspectors wishing to inspect the plumbing drain lines on their client’s home will now have a unique tool designed specifically for the home inspector to quickly and easily view and record the drain lines condition.

Subtech and Jack Felix have been designing and manufacturing Pipeline Inspection Cameras since 1992 and in recent years, working along with Nick Gromicko and Jim Krumm of the Sewer Scope Training Class for InterNACHI, we have created a unique camera system that is being used by home inspectors worldwide.
