How to Use the Pump Room to Drain Water in Blue Prince Game

Unlocking the secrets beneath the shimmering waters of Blue Prince begins in the enigmatic Pump Room-where mastering a maze of levers and pipes lets you drain the Pool and reveal hidden treasures. Ready to dive in? Here’s how to navigate the Pump Room’s controls to lower the Pool’s water level and uncover what lies beneath.

By accessing the control panel and pumps inside the Pump Room, you can fill and drain water sources like the pool and kitchen. However, controlling the water flow is a puzzle in itself. Similar to water jug puzzle from Die Hard With A Vengeance (just without the bomb), you’ll need to raise and drain water sources and tanks to get the perfect amount of water.

Here’s how to use the Pump Room in Blue Prince, including step by step example on how to drain the Pool.

How to use the Pump Room in Blue Prince

To use the Pump Room in Blue Prince, first ensure you have unlocked the Pool, as this adds the Pump Room to your drafting options. Inside the Pump Room, you’ll find a control panel and several pumps connected to tanks that hold water units. To drain the Pool, select it on the control panel, then operate Pump 4 by pulling its lever up to start draining water from the Pool into the tanks. Since the tanks have limited capacity, you may need to transfer water between areas using other pumps to free up space and fully drain the Pool. The Pump Room schematic on the wall helps you understand which pipes and pumps correspond to each area, making it easier to manage water levels and reveal hidden secrets beneath the Pool and other locations.

Before using the water pumps, first, brush up on the items you’ll find in the Pump Room and how they work:

Mt. Holly Pump Control Panel. This controls which water source will be adjusted. There are six buttons labeled “Fountain,” “Reservoir,” “Aquarium,” “Kitchen,” “Greenhouse,” and “Pool.” Above each button, you’ll find a set of bars that indicates how much water is in each area. If the bars are completely blue, that water source is full of water. If the bars are completely gray, that water source is empty.
Pipes. There are six pipes connected to the wall with each pipe tied to one of the water sources on the control panel. The pipes on the wall will match the same order found on the control panel, with the first pipe being the Fountain, the second being the Reservoir, and so on.
Pumps. There are four pumps that connect the pipes to the tanks. The pump levers will control the water flow direction.
Tank Switch. This controls which tank Pump 2 will pump or drain water to. It can be found on the pipe connecting Tank 1 and Tank 2.
Tanks. There are three tanks, two holding four units of water and one being a reserve tank that must be powered by the Boiler Room.

To pump or drain water, follow these steps:

Select a water source on the control panel by pressing its respective button.
Follow its respective pipe to its pump.
Change the direction of water flow by raising or lowering the pump lever.

It’s important to note that any changes made to water sources around the estate will last to the next day. For example, if you’ve drained the pool, it’ll stay drained until you change it in the Pump Room.

How to drain the Pool in Blue Prince

To drain the Pool in Blue Prince, first ensure you have drafted the Pool room, which unlocks the Pump Room in your manor. Inside the Pump Room, locate Pump 4 positioned behind Tank 1. Use the control panel to select the Pool as the target water source, then pull the lever for Pump 4 upwards to start draining water from the Pool into Tank 1. You can manage water flow between Tank 1 and Tank 2 using the switch near Pump 4 at the back of the room. This process allows you to lower the Pool’s water level and discover hidden items at the bottom.

As an example on how to use the Pump Room, here’s how to drain the Pool in Blue Prince.

If you’ve been to the Pump Room before, your water levels might be different if you’ve already rearranged the water levels. As a base, we’ll be using the Pump Room’s initial water levels when you first enter the room.

Before you can drain the Pool, you’ll need to free up some space in one of the larger sources, such as the Fountain or the Reservoir.

To do so, you’ll need to drain water from the larger sources into Tank 2 and pump that water elsewhere like the Kitchen. Then, you’ll need to drain water into Tank 2 again to free up enough space so that all of the water from the Pool can go into the Fountain or Reservoir.

To drain the pool, follow these steps:

Select the Pool button on the control panel.
Walk over towards Pump 4, which is located behind Tank 1, then pull the pump lever up to direct water into Tank 1.
Press the Greenhouse button on the control panel.
Push the lever on Pump 1 down to direct the water from Tank 1 into the greenhouse.
Interact with the tank switch located behind and between Tanks 1 and 2 so it points point toward Tank 2.
Select the Fountain button on the control panel.
Pull the lever on Pump 2 up to direct water into Tank 2.
Select the Kitchen button on the control panel.
Pull the lever on Pump 3 down to direct water into the Kitchen.
Select the Fountain button on the control panel to drain water from the Fountain into Tank 2.
Select the Pool button on the control panel to drain water from the Pool into Tank 1.
Interact with the tank switch located behind Tank 1 and 2 to point towards Tank 1.
Push the lever on Pump 2 down.
Press the Fountain button to pump water from Tank 1 into the Fountain.
Press the Pool button to drain water into Tank 1 and completely drain the Pool.

How can I activate the Pump Room to drain the Pool in Blue Prince

To activate the Pump Room and drain the Pool in Blue Prince, follow these steps:

First, draft the Pool room in your run to unlock access to the Pump Room.
Inside the Pump Room, locate the control panel and press the button for the Pool to select it.
Find the lever for Pump 4, which controls the Pool’s water flow.
Use the switch near Pump 4 to select either Tank 1 or Tank 2 as the water source. This switch only affects the Fountain and Reservoir tanks, but for the Pool, you will primarily use Tank 1.
Push the Pump 4 lever down (away from you) to drain water from the Pool into Tank 1.
Since the Pool holds 9 units of water and each tank holds only 4 units, you must first free up space in Tank 1 by draining water from it into another area (like the Fountain or Reservoir) using their respective pumps and buttons.
Once Tank 1 has enough capacity, continue draining the Pool until it is completely empty.

By carefully managing the tanks and pumps, you can fully drain the Pool and access any hidden rewards at the bottom.

What is the exact sequence to push the Pump 2 lever for draining

The exact sequence to push the Pump 2 lever for draining in a system like the Pump Room in Blue Prince involves these steps:

Identify the Pump 2 lever in the control panel.
Select the appropriate tank or water source for Pump 2 using the nearby switch.
Push the Pump 2 lever down (away from you) to initiate draining.
If the tank is full, you may need to first drain water from the tank to another location to free capacity.
Continue operating Pump 2 by holding or repeatedly pushing the lever as needed until the desired drainage is achieved.

This sequence is consistent with typical pump drainage system operation where levers control flow direction and pumps must be primed or tanks managed to allow continuous drainage.
