🔍 Key Concepts

• MODU fire main system layout and purpose • Location where pump discharge pressure is most accurately measured • Difference between pump location, manifold, and fire stations

💭 Think About

• Where do you need to know the pump’s actual discharge pressure to be sure the fire main is working as designed? • Which location is common to all fire lines and not dependent on how many branches or fire stations are open? • Think about where adding a gauge would give engineers and operators the quickest way to verify pump performance.

✅ Before You Answer

• Identify which option describes the immediate outlet of the pump, before the system branches out • Eliminate any locations that vary a lot depending on how many fire stations you have • Focus on the point in the system where pump performance (not local line losses) is best indicated
