How many feet of vertical CPVC must be supported at each floor level?

The requirement that vertical CPVC (Chlorinated Polyvinyl Chloride) must be supported at each floor level is based on the need to ensure stability and prevent sagging or bending over time. Each floor provides a secure point for support, which is crucial for maintaining the integrity of the piping system. This method of support minimizes stress on the fittings and the material itself, reducing the likelihood of leaks or failures that could be caused by unsupported sections of the pipe.

In addition, supporting CPVC properly at every floor level helps in complying with building codes and industry standards, which are designed to guarantee the safety and functionality of plumbing installations. Properly installed and supported piping systems contribute to the overall reliability of the plumbing infrastructure within a building.
