The correct answer is: Both materials and fixtures

Plumbing codes are comprehensive regulations that ensure safety, health, and efficiency within plumbing systems. One critical aspect these codes regulate is the materials used in construction, as certain materials can affect water quality, system durability, and overall safety. For instance, specific pipe materials must comply with standards to prevent contamination and ensure longevity under varying pressures and temperatures. In addition to materials, plumbing codes also regulate the types of fixtures installed. This includes everything from sinks and toilets to showers and bathtubs, with guidelines on their design, installation, and performance. Codes often specify minimum water flow rates, requirements for accessibility, and even performance standards for fixtures to ensure they function correctly and efficiently. The inclusion of both materials and fixtures is vital as plumbing systems must operate seamlessly together. This integration ensures that the entire system adheres to safety standards and performs effectively, which is the essence of plumbing codes.
