If you suspect a leak in the discharge system during testing, what is the appropriate action?

• A. Tighten all fittings only
• B. Continue testing aggressively to verify leaks
• C. Dismiss leaks as minor and proceed
• D. Stop, inspect for leaks, check hoses and valves, and repair as needed

Answer: (D)

When a leak is suspected in the discharge system, the proper action is to stop the test and inspect the system for leaks, then repair as needed. Stop the pump, relieve any pressure safely, and examine hoses, fittings, valves, and seals for looseness, cracks, or damage. If a fault is found, tighten or replace components as appropriate and verify the system is leak-free before resuming testing. Continuing or ignoring leaks can lead to unsafe pressures, fluid loss, or equipment damage, and simply tightening everything without locating the source may not fix the real issue.
