Shortly after reaching the Brentwood Sewers in Dead Island 2, you will encounter an obstacle in the form of a locked floodgate, which blocks you from exploring the western part of the map. This page explains how to solve the puzzle with setting the correct pressure - you need to set the values to 010, 075 and 045.
Location of the pressure puzzle - Brentwood Sewers
You will reach the Brentwood Sewers location for the first time during the Flushed main quest. Not long after you start exploring the sewers, you will come across a closed lock.
Opening the lock requires solving the pipe pressure puzzle. Check the west room (Automated Hydrostatics Monitoring). It's locked, but you'll find a manual by the bars and, along with it, a BWRP Hydrostatic Keycard.
Pressure puzzle solution
You can use the access card and get to the Hydrostatic Management System on the map. You need set the correct pressure a total of 3 times. The required values appear on the machine counters in the last room.
The first part of the puzzle is to get the value of 10. Reach the last room and take the water canister. Use the canister to get rid of the green substance from the side room.
You can now take the Valve Wheel. Return to the first corridor and insert the valve into the slot by the pipe with a value of 10. Then use the valve.
The second part of the puzzle is to get a value of 75. You start with value 10 from the first part and have to add more.
A pipe with a value of 20 is in the side room. When you pull the lever, it will slowly begin to return to its default position (and turn off), so you must hurry with the next step.
Reach the pipe with a value of 45 quickly. Pull the lever and you should get the desired value of 75 (10 20 45).
The third part of the puzzle is to get the value of 45. After the 2 levers get reset, you will return to the value of 10. Reach the valve from the first part of the puzzle - you have to turn it to go from 10 to 0.
You must now once again use the lever with value 45.
Watch out for new monsters that will appear in the corridor and in the main room. After the battle, you will be able to use the open western floodgate and resume exploring the sewers.
