What is a typical symptom of a clogged discharge outlet?

• A. Reduced nozzle pressure and insufficient water flow on the attack line
• B. Increased nozzle pressure
• C. No change in flow
• D. Higher water temperature at discharge

Answer: (A)

When a discharge outlet is clogged, the water path from the pump to the attack line is restricted. The pump may still push water, but the blockage limits how much water can actually leave, so the water that reaches the nozzle is reduced. That shows up as lower nozzle pressure and insufficient flow on the attack line. The other options don’t fit because a restriction doesn’t cause higher nozzle pressure, and it does change the flow. Higher discharge temperature isn’t a typical indicator of a clog.
