Which statement best describes securing caps and plugs on a water spray system during testing?

• A. Be in place and free to operate as intended
• B. They must be removed during testing
• C. They can be secured with tape
• D. They should be glued in place

Answer: (A)

During testing, caps and plugs belong where they are in the system and must be left in place so the hydraulics and seal integrity reflect normal operation. They keep the test from creating unintended leaks or alternate flow paths that would skew results, and they prevent debris or moisture from entering the system. Removing them would alter pressure and flow conditions, leading to inaccurate test outcomes. Tape or glue is not acceptable because it isn’t a reliable, code-compliant way to manage these fittings and could prevent proper removal or fail under pressure. Keeping caps and plugs correctly secured and in place ensures the test verifies the system under its intended conditions.
