Identify Plumbing Materials and Connections

What happens here

Upon closer inspection, the 'plumbing system' is constructed from both black ABS (Acrylonitrile Butadiene Styrene) and white PVC (Polyvinyl Chloride) pipes and fittings. A variety of fittings are visible, including numerous 90-degree elbows, T-junctions, and straight pipe sections, all interconnected to form a dense, branching network. These connections appear to be solvent-welded or press-fit, standard methods for joining these pipe types. White zip ties are extensively used to secure different pipe sections to each other and to the underlying frame, suggesting a non-permanent or modular assembly. This configuration is not typical for a hydrostatic pressure test, which would require a sealed system designed for holding specific pressures and often a more linear, less decorative layout.

Goal: A closer look reveals the specific types of plumbing pipes and fittings used, distinguishing between black ABS and white PVC components, and how they are interconnected.
