How close should the fixture water supply pipe be extended to within for residential structures?

10 inches
20 inches
30 inches
40 inches

The correct answer is: 30 inches

The correct distance to which the fixture water supply pipe should be extended for residential structures is 30 inches. This standard ensures that the plumbing system is adequately prepared for the fixtures that will be connected, allowing for proper installation and maintenance. The 30-inch distance provides enough flexibility to accommodate necessary adjustments during fixture installation while ensuring compliance with building codes that dictate how plumbing should be routed to fixtures. In residential plumbing, this measurement helps to standardize practices across installations, promoting safety and functionality within the plumbing system. Understanding this distance is essential for plumbers as it influences how and where water supply lines are installed, impacting not only the performance of the fixtures but also ensuring that building safety and accessibility standards are met. Adhering to these guidelines demonstrates a plumber’s commitment to quality and regulatory compliance within the plumbing trade.
