True or False: No part of a drain, waste, and vent (DWV) system can be joined or fitted with a solder or flux containing more than 0.2 percent lead according to the Illinois Plumbing Code.

  1. True

  2. False

The correct answer is: True

The statement is true. The Illinois Plumbing Code mandates that any solder or flux used in the assembly of drain, waste, and vent (DWV) systems must contain no more than 0.2 percent lead. This regulation is designed to protect public health by ensuring that the plumbing systems do not contribute to lead contamination in drinking water and other uses. The emphasis on minimizing lead content aligns with broader public health goals and regulations aimed at reducing exposure to hazardous materials in plumbing systems. Thus, adherence to this standard is crucial in maintaining safe and compliant plumbing practices within the state.
