Blue Prince presents an intriguing puzzle challenge, enriched with a diverse array of engaging content. To completely navigate the game’s expansive environment, players must connect various rooms, establish power lines across tiles, unlock additional floorplans, and tackle numerous other tasks.
Among the game’s many mysteries, the Pump Room stands out as an especially challenging area. With its array of levers, buttons, and dials, players might find themselves in need of some guidance. Below, you’ll discover essential insights and tips to help you master the Pump Room.
Unlocking the Pump Room

To access the Pump Room floor plan in Blue Prince, your first objective is to locate the Pool area. Recognizable by its three entrances, the blue room is dominated by a sizable swimming pool. Successfully interacting with the Pool will unlock additional spaces, including the Pump Room, Sauna, and Locker Room. Notably, players can empty the Pool entirely by figuring out the mechanics of the pumps.

To drain the Fountain after making a wish, you’ll need to fill all other rooms with water, then transfer the remaining water from the Fountain into one of the tanks. This process involves utilizing a water source that provides access to both tanks 1 and 2. Be sure to utilize the Pump 2 Switch to designate the appropriate tank for water flow.
Emptying the Reservoir
If you’ve been experimenting with the pumps, you might notice the limited capacity for water in the surrounding sources and tanks. To access the bottom of the Reservoir, activating the Reserve tank on the opposite side of the Pump Room is essential. This requires connecting power to the Pump Room via a source, specifically the Boiler Room in Blue Prince.

Various floorplan tiles, such as those found in the Archive, Gym, and Lab, can link power to different areas. After activating the power in the Boiler Room, observe the highlighted tiles that can transmit power. Once the connections are established, you’ll gain access to new controls within the Pump Room, allowing you to drain either tank 1 or tank 2 into the Reserve tank situated across the room.
