How to find the Hydro-Puzzle safe
First, you’ll meet this safe while doing the “Hydro-Puzzle” side quest. To trigger that quest, finish “Power Gambit” and then start the main quest “A New Strain.” After that, you’ll get a message from Pietro asking you to check water pressure at a nearby Pumping Station.
Go into the Pumping Station and check the pressure meter. Note that several zombies appear awake as soon as you enter, so either rush the meter and run, or clear the room before exploring. After that step, Pietro asks you to search the chief engineer’s office at the Waterworks Repair Facility.
To reach the office, climb to the roof, enter the open air vent, and crawl inside. The Hydro-Puzzle safe sits in that office area; it’s tucked away, so look around carefully and clear any nearby enemies before fiddling with it.
Once you’re in the office, there’s a locked door to the left when you leave the safe room. It’s a *very easy* lock, so if you don’t have a lockpick, craft one from the crafting menu. You’ll need three scraps to make a lockpick; loot zombies or dismantle a weapon if you’re short.
Hydro-Puzzle safe code
After opening that left door and clearing the small room, check the desk for a note. The note lists the safe code. The code is 27-01-15.
Enter 27-01-15 into the safe to get a wristwatch and a key to the chief engineer’s office. Then, head left from the safe room and clear the large storage area to unlock access to the engineer’s space below.
Next, go to the Sewer Maintenance Point in Old Town. You can lockpick the door, then follow the yellow pipe to the source of the clunking noise in the sewers. Expect a tough fight with many undead down there. Once you clear the building, the “Hydro-Puzzle” quest completes and the water issue progresses.
