- Pump Room configurations persist between runs unless manually altered
Discover what mysterious secrets lie concealed beneath the Fountain structure in Blue Prince’s manor grounds.
Are you attempting to empty the Fountain in Blue Prince? This decorative water feature may appear purely aesthetic initially, but experienced players quickly learn that every environmental element serves multiple purposes. Some lead to entirely new gameplay areas, while others reveal narrative clues about the manor’s history. Please note this guide contains minor spoilers about game progression mechanics.
Gaining entry to the Pump Room requires specific room drafting strategy. You must first select a Pool during your manor construction phase. Once a Pool exists in your current run layout, the game automatically adds Pump Room, Sauna, and Locker Room to your daily draft selection pool.
The challenge lies in the random selection system—you’ll need favorable RNG outcomes to have the Pump Room appear as an available choice when drawing rooms. Many players recommend saving your draft attempts for days when multiple water-related rooms appear together, increasing efficiency.
Before attempting to manipulate water levels, thoroughly study the Pump Room’s intricate mechanical systems. The wall diagram provides essential operational understanding:
- The system features two primary storage tanks—designated Tank 1 and Tank 2—plus an auxiliary reserve tank (irrelevant for Fountain draining).
- Three main pumps with control levers position before the primary tanks: Pump 1 (left position), Pump 2 (central placement), and Pump 3 (right location).
- A secondary pumping unit—Pump 4—occupies the rear section of the chamber.
Lever manipulation follows intuitive physics: pulling downward initiates water filling sequences, while pushing upward activates drainage procedures. Maintaining levers in neutral middle positions halts automated water transfer functions.
The diagram shows how the Pump Room’s mechanisms work.
The central control panel displays all water-manipulable locations throughout the manor. Select your target area by pressing its corresponding interface button, then adjust hydration states through connected pump mechanisms:
- Fountain – Controlled by Pump 2.
- Reservoir – Also managed through Pump 2.
- Aquarium – Regulated via Pump 1.
- Kitchen – Water levels adjusted using Pump 4.
- Greenhouse – Hydration controlled by Pump 1.
- Pool – Water volume managed through Pump 4.
Additionally, a configuration toggle near the rear Pump 4 unit enables switching between Tank 1 and Tank 2 utilization during water level modifications.
Approach the Blue Prince Pump Room challenge as a strategic resource allocation puzzle. The control interface displays small indicator dots representing current water volumes. The Fountain begins with 12 active pips indicating maximum capacity. Your objective involves reducing this count to zero through systematic water redistribution:
- Initiate partial Fountain drainage using the central pump mechanism (Pump 2). Utilize both primary tanks by activating the rear positioning switch.
- Redirect displaced water to supplement other manor locations: Kitchen (consumes 3 levels), Greenhouse (requires 4 levels), and Pool (needs 1 level).
- This redistribution strategy leaves only 4 active pips remaining in the Fountain system.
- Complete the drainage procedure by transferring final water volumes into storage tanks.
Important: The Fountain maintains its drained state across subsequent gameplay sessions unless Pump Room configurations undergo modification. Any adjustments to other water-controlled areas necessitate redrafting the Pump Room.
We’ve got the Fountain fully drained by transferring water to other rooms, and by filling up the tanks.
Following successful Fountain drainage in Blue Prince, investigate the exterior manor location. The newly revealed staircase descends into previously inaccessible Underground regions.
Note: The portal beneath the Fountain entrance remains secured initially, requiring acquisition of the Basement Key from the Antechamber. Any Underground access point unlocked using the Basement Key maintains permanent accessibility.
Beyond Fountain manipulation, numerous other areas permit water level adjustments. Draining the Pool frequently reveals hidden collectibles, while the Aquarium often contains environmental storytelling elements. The Reservoir represents perhaps the most significant explorable zone, containing narrative-critical discoveries. For comprehensive underground navigation assistance, consult our specialized Underground guide. Foundation elevator operations receive detailed coverage in our Foundation elevator guide, while hydraulic system mastery is covered in the Reservoir guide.
Blue Prince delivers an extraordinary adventure brimming with enigmatic wonders and concealed mysteries. Should you encounter progression obstacles during your exploration, remember to reference our extensive Blue Prince guides hub for additional support.
