What level of water discharge should the packing glands have?

• A. Slight
• B. Moderate
• C. Heavy
• D. None

Answer: (A)

Packing glands on a fire pump are meant to release a small amount of water to lubricate and cool the packing around the shaft. A slight discharge shows the packing is properly lubricated without letting too much water escape. If the discharge were moderate or heavy, it would mean excessive leakage, which can waste water and indicate worn packing or a loose gland. If there were no discharge at all, the packing might be too tight or sealing improperly, risking overheating and damage. So, the best answer is a slight water discharge because it balances lubrication with minimal leakage.
