Common questions
Why does packing leak on purpose?
A slow drip cools and lubricates the packing and shaft sleeve. Over-tightened packing runs dry, overheats and scores the sleeve.
Which questions apply to wastewater?
Pump, motor and safety questions are shared. Drinking-water items such as residential meters only appear on water exams; wastewater items such as sludge pumps only on wastewater exams.
