What is the purpose of tightening hose valve caps during manual valve testing?

• A. To prevent rusting
• B. To prevent unauthorized use
• C. To prevent leaking during the test
• D. To seal against pressure loss after test

Answer: (C)

During manual valve testing, the goal is to verify the valve and its connections by applying pressure and watching for leaks. Tightening the hose valve caps creates a sealed outlet, so water cannot escape through the hose connections while the test pressure is applied. This containment is essential for obtaining accurate test results and for preventing water spray or pressure loss that could mask leaks elsewhere in the system. Other options aren’t the primary focus here: the caps aren’t mainly about preventing rust, security against unauthorized use, or sealing after the test. They serve to stop leakage during the test itself, ensuring the test is valid and the pressure remains where it should.
