Whether you are looking for the location of all the water valves or want to know how to solve the water pressure puzzle in the McMillan Reservoir Assault Classified Assignment in The Division 2, I’ve got you covered with this guide.
For players who don’t know, there are two water valve or pressure, whatever you like to call it, puzzles in the latest McMillan Reservoir Assault Classified Assignment.
The first one that you come across is required for progressing the quest, while the other one drops the Silo 28 Key, which holds the new Bigfoot Backpack Trophy, an Audio Log, and a True Sons Cache.
In the wake of that, solving these two puzzles is a must for every player, and there’s a high chance that you may get stuck on it, especially on the second one.
This is where my guide comes in handy.
McMillan Reservoir Assault water pressure/valve puzzle 1
In The Division 2 McMillan Reservoir Assault Classified Assignment, the first water pressure puzzle is found within the Pump House.
Once you enter it, you will get the objective to “Correct the water pressure.”
Head to the first floor of the Pump House.
Look at the water pressure meters found in the middle of the room. Note down the pipe numbers and their corresponding pressures.
Note: Each run has a different pressure reading.
Once done, now it’s time to find the three pipes and fix the pressure.
The first water valve is found inside the Pump House Control 01 Room, at the above location, left of the pressure meters.
To access the room, you need the Pump House Control 01 Key. I already have a guide on its location. Check it out.
Once you are inside the room, reset the pressure if required and set it to the reading as shown in your game for Pipe 1.
The second pipe/valve is found at the above player icon location, inside the room found right of the pressure meters.
Set the pressure corresponding to Pipe 2 in your game.
While you are in the room, shoot down the circuit through the door to access the third pipe room.
For the third pipe/water valve, head to the ground floor of the Pump House. The electrified door should now be accessible.
Take the ladder to reach the room above. Set the pressure as per the readings in your game.
Shoot the padlock and exit the room.
Pull the lever to fix the pressure.
McMillan Reservoir Assault water pressure/valve puzzle 2
The second water pressure meters/puzzle is found right outside of the Pump House.
Head to the above player icon location. Once you arrive there, note down the pressure readings for each colored pipe.
Unlike the previous puzzle, we don’t have the 1, 2, and 3 markers on the pipe. Instead, we must identify them using the pipe colors: GREEN, BLUE, and YELLOW.
For the Green Pipe, progress the quest until you reach the water storage.
Progress until you collect and place the explosives and get the objective to exit the area.
Near the exit, on the left side, you will find the Green Pipe’s Valve, blocked by two container gates.
Shoot down the barrel on the right side to get rid of the container doors.
Climb up and set the pressure as per the readings in your game.
The Yellow Pipe is located below the Radio Tower area.
I have marked it in the above screenshot.
To set the pressure, you must first fix the fuse box. It is missing a fuse.
I already have a guide on where to find the Fuse. Check it out.
Assuming you have the Fuse, place it in the box and set the pressure for the yellow pipe as per the readings in your game.
To access the final pipe, the Blue one, follow the above marked path from the Yellow Pipe’s location.
At the above player icon location, shoot the padlock on the two doors as marked.
Now, go through the side door.
Set the water pressure for the Blue Pipe as per the readings in your game.
That’s it. Now that you have set the water pressure for the Green, Yellow and Blue pipes, head back to the pressure meter.

Pull the lever.
Collect the Silo 28 Key.
Head to the Silos area.
Open Silo 28 and collect the Bigfoot Backpack Trophy and other stuff.
