🔍 Key Concepts

• Relationship between air charge in a hydro-pneumatic (compression) tank and system pressure fluctuations • How a pressure switch starts and stops Pump "A" based on system pressure (cut-in vs cut-out) • What short cycling means for a pump in a potable water pressure system

💭 Think About

• Look at the compression tank in the illustration: when the pump stops, what keeps pressure on the distribution system, and what role does the trapped air play? • If the air volume in the tank is too small or too large, how does that change the amount of water that can be drawn before the pressure switch reaches its cut-in or cut-out setting? • Which listed condition would cause the system pressure to bounce quickly between the pressure switch settings, forcing Pump "A" to start and stop frequently?

✅ Before You Answer

• Be clear on the definition of short cycling: very frequent pump starts and stops over a small pressure range. • Ask which option mainly affects the compressibility / storage capacity of the system, rather than pump efficiency or suction supply. • Verify from the illustration which component (not Pump "A" itself) is primarily responsible for smoothing pressure changes and providing draw-off volume between pump cycles.

According to the illustration, which of the following conditions would most likely cause Pump "A" to short cycle? Illustration GS-0173

The hydro-pneumatic expansion tank is operating with an insufficient air charge.

The hydro-pneumatic tank is operating with a low water level.

A low water level exists in the potable water storage tank.

Pump "A" wearing rings have excessive clearance.
