🔍 Key Concepts

• Hydropneumatic (pressure) tank operation in small potable water systems • Difference between pressure control and level control for pumps • How to avoid continuous pump operation and unnecessary wear in low-demand systems

💭 Think About

• Which option describes a method that keeps fairly constant pressure in the distribution piping, even when faucets open and close quickly? • Think about which control method would require fewer pump starts and stops on a small, low-use system: tank level switches or a pressure switch on a small pressure tank? • Which options would be harder on the pump over time (running against shut-off head or recirculating) versus using automatic control based on system conditions?

✅ Before You Answer

• Identify which choice mentions a pressure switch rather than a level switch. • Check which method would maintain steady line pressure without the pump running all the time. • Eliminate any options that would cause the pump to run continuously with no real flow, as this is usually avoided in small potable water systems.
