I have problem with puzzle in abandoned building. I did bring the right pressure reading to all required pressure points . After that , I placed pipes from inventory on empty spaces. Than I connected the tip of the blowtorch on the release nozzle that has 100 pressure reading, welded to seal 3 pipes from inventory. but when I placed blowtorch at the top left - Holmes said : 'It isn't enough gas, the pressure isn'n high enough'.
What could I be missing ? All previous epizodes and puzzles was done right. Please, help me! Any ideas would be helpful . In inventory I have 3 items - knife, perfume atomizer and rusted iron dishes(?).

Hi joky,

Did you weld all pipe sections completely?

Take a look at THIS YouTube video excerpt, it should help you figure out what you might have missed doing.

, let us know how you get on.

Read the walkthrough carefully - there is one with good images of the valve positions: I had this same problem but solved it by checking I chose the correct valve directions. Also, I think the game MAY be a bit buggy, so get in the habit of saving frequently in this game (and most others, it cannot hurt!) so you can reload an older save if needed.

Hi, I got it ! A thousand thanks all of you for a kind help !

Great!
Enjoy the rest of the game.
