on

The Blue Prince might seem like a cozy puzzle game on the surface, but once you dive into the estate’s darker corners—especially the mysterious Pump Room—you’ll realize there’s a lot more going on. In this guide, we’re going beyond the basics and revealing the hidden interactions, secret passages, and clever mechanics that the Pump Room hides behind its valves and levers.

If you’ve ever asked yourself “What happens if I drain this water…?”—you’re in the right place.

💡 What is the Pump Room in Blue Prince?

If you’re new to it: the Pump Room is a utility hub tucked within the Mt. Holly estate that lets you control water flow between tanks and different estate zones like the Fountain, Reservoir, Greenhouse, and more.

It's got:

  • ✔️ Four main levers for controlling water direction

  • ✔️ Two tanks (plus a reserve tank if you’ve unlocked it)

  • ✔️ A control panel showing current water levels

  • ✔️ Pipes that connect to critical estate locations

And here’s the kicker: it's not just about puzzles—what you do here can reveal secret areas, open new shortcuts, and even unlock hidden items.

🕵️‍♂️ Hidden Secrets & Interactions You Don’t Want to Miss

🪜 1. Draining the Fountain Reveals Hidden Staircases

When you completely drain the Fountain, you may notice something subtle—there’s a spiral staircase that appears at the bottom. It’s easy to miss unless you're paying attention, but it leads to a secret chamber with lore notes and sometimes even a hidden item drop.

🧠 Tip: You need to route water from the Fountain to the Main Tank, then drain the tank afterward to fully clear the area.

🗝️ 2. Reservoir Tricks – Unlocking Submerged Doors

The Reservoir has a secret underwater chamber that becomes visible when the water is lowered just right. If you drain it too much, you won’t see it; too little, and you can’t enter it. It’s all about precise control.

You’ll find a half-submerged doorway behind a rock wall near the edge once you’ve hit the sweet spot.

🧠 Tip: Watch for bubbling water and mossy walls—they’re often subtle clues that something is hidden nearby.

🧬 3. Persistent Water States Between Runs

One wild mechanic that many players overlook: water levels persist between runs. Yep, drain a pool today, and it’ll stay drained tomorrow—unless you reset it manually.

That means:

  • You can set up future shortcuts

  • Solve multi-day puzzles

  • Slowly uncover areas that require precise setups across multiple days

🧠 Tip: Keep a journal or screenshot your Pump Room settings at the end of a run. It’ll save you time and confusion later.

🥀 4. Greenhouse Growth Mechanic

If you pump water into the Greenhouse, certain plants will grow and reveal climbing paths or item caches hidden in vines. Some players have even found staircases hidden under overgrown roots once the area becomes lush.

🧠 Tip: Run water into the Greenhouse for at least two days in a row for full effect.
