Q

When stripping a tank, what is caused by excessive air in the suction line?

🔍 Key Concepts

• Stripping a tank means removing the last remaining liquid with a pump • Effects of air entering a pump suction line • Difference between suction problems vs. pressure problems in a pipeline

💭 Think About

• Think about what happens inside a pump when it starts pulling mostly air instead of liquid—does that help or hurt its ability to lift liquid? • Which of these choices would you normally associate with a pipe that is too full of liquid versus a pipe that has a lot of air in it? • If air is in the suction side, does it make the pump move liquid more easily or lose its ability to move liquid?

✅ Before You Answer

• Compare which answers describe a pressure build-up versus a loss of pumping ability • Remember that suction side problems usually affect the pump’s ability to draw liquid up from the tank • Eliminate any options that would more likely occur on the discharge side (pressure side) of the pump rather than the suction side
