Rhode Island Journeyman Plumber Practice Exam

What should happen to the slip joints on a tub waste during testing?

1. They should remain loose

2. They should be sealed

3. They should be checked for leaks

4. They should be removed

The correct answer is: They should be checked for leaks

The correct response emphasizes the importance of ensuring that all components of a plumbing system, including slip joints on a tub waste, are functioning properly during testing. When testing a plumbing system, it's crucial to check for leaks at all joints, as this verifies the integrity of the system and ensures that there are no potential failure points that could lead to water damage or plumbing issues in the future. Slip joints are designed to allow for flexibility and adjustment during installation and maintenance. However, during a comprehensive test, confirming that these joints do not leak is essential. This can involve running water through the system while monitoring the slip joints for any signs of leakage. If leaks are present, they must be addressed before the system can be considered reliable and ready for use. While it might seem reasonable to think that slip joints should be sealed, the nature of these joints typically requires them to allow for disassembly. Removing them during testing doesn't make practical sense as it would undermine the purpose of the test, which is to assess the system's functionality. Therefore, ensuring that they are leak-free is the primary concern during the testing phase.
