Step 5: There you go you earned enough CAPS to buy new gears,refill your ammos,buy explosives and even buy Legendary/Unique Gears and Weapons.
Step 3: After you connect your Water Purifiers-Industrial leave them, because Purified Water don't generate at faster rate( I suggest you explore the commonwealth do side-quests or just do the Dora the Explorer thing)(PS: I don't suggest you to wait or sleep 24 hours because it won't work just leave them) Step 4: Once you played the game over an hour or more goo back to your Settlement and check the Workshop if you have enough Purified Waters let's say x100 Purified Waters sell them. Step 2: Connect them to Medium Generators because they require 5 Power in order to run.
Step 1: Build 4 or more Water Purifiers-Industrial.
