🏰 How to Reach the Blue Prince Pump Room

To access the blue prince pump room, you first need to draft a Pool for your current run. Once you have a Pool in your manor, you can unlock several other areas, including the Pump Room, Sauna, and Locker Room. These areas will be added to your draft options for the day, giving you a chance to select them. However, the appearance of the blue prince pump room relies on RNG (Random Number Generation), so you may need to be lucky for it to show up when you draw rooms.

💡 How to Use the Pump Room in Blue Prince

Before you start using the pumps in the blue prince pump room, it's important to understand the components you'll be working with. Here's a breakdown of the items you'll find in the pump room and how they function:

1️⃣ Mt. Holly Pump Control Panel

This panel controls which water source you'll adjust. The panel has six buttons labeled with different water sources:

• Fountain

• Reservoir

• Aquarium

• Kitchen

• Greenhouse

• Pool

Each button has a set of bars above it that show how much water is in each area. If the bars are fully blue, the water source is full, and if they're completely gray, it’s empty. This panel is where you’ll begin your work in the blue prince pump room.

2️⃣ Pipes and Pumps

There are six pipes connected to the wall, each one corresponding to the water sources listed on the control panel. The pipes are arranged in the same order, starting from the Fountain to the Pool. The pipes connect to four pumps that control the direction of the water flow. Adjusting the pump levers allows you to manage the flow of water between the different sources and tanks.

3️⃣ Tank Switch

The tank switch is essential for controlling which tank Pump 2 will pump or drain water to. This switch can be found on the pipe connecting Tank 1 and Tank 2, so be sure to use it when you need to manage water distribution across your tanks.

4️⃣ Tanks

There are three tanks in the blue prince pump room, two of which hold four units of water each. The third tank is a reserve tank, which must be powered by the Boiler Room to function. Managing the tanks effectively is key to your success in the blue prince game.

🚰 How to Drain the Reservoir in Blue Prince

To drain the fountain or reservoir in the blue prince pump room, follow these steps:

1. Select a Water Source
   Start by pressing the button on the Mt. Holly Pump Control Panel for the fountain or reservoir you want to work with.

2. Follow the Pipe
   Once selected, follow the corresponding pipe to the pump connected to that water source.

3. Adjust the Pump Lever
   Change the direction of the water flow by raising or lowering the pump lever. This will either pump the water to the tanks or drain it from the selected source.

It’s important to remember that any changes made to the water sources in the blue prince pump room will persist until the next day. For example, if you've drained the pool or fountain, it will stay drained until you adjust it again in the pump room.

🔄 Managing Water Flow Across the Estate

You can adjust water flow to multiple areas at once by using the blue prince pump room to direct water from the fountain, reservoir, or other sources. By strategically draining and filling these areas, you can optimize your gameplay and unlock various features in the blue prince game.

🔄 How to Drain the Fountain in Blue Prince

To begin draining the fountain in the blue prince pump room, follow these steps carefully:

1. Use Pump 2
   The first thing you’ll need to do is use the middle pump (Pump 2). This pump will partially drain the fountain water. You can also utilize both tanks by flipping the switch at the back of the pump room.

2. Transfer Water to Other Areas
   To make the process more efficient, redirect the drained water to other locations. For example, you can use the kitchen (draining -3 levels), the greenhouse (draining -4 levels), and the pool (draining -1 level). By doing so, you will reduce the amount of water in the fountain and help maintain control over the water levels.

3. Check the Water Levels
   After transferring water, you’ll be left with +4 levels/pips for the fountain. This means the fountain is now partially drained but still holds some water.

4. Final Adjustment
   To fully drain the fountain in the blue prince pump room, continue draining water into the tanks and adjust the levels accordingly. Once you’ve finished, you will have successfully reduced the fountain water level to zero.
