room upgrades

I bought a room upgrade a few generations ago, and this weird thing is placed in the tray, but i couldn't move it or do anything with it, and if I exited the game and came back, it was gone! Then I tried to look it up and saw something about needing to lower the water pressure first? Why can I not use a room upgrade? :( please help! And I'm not playing on my computer, I'm playing on my Android phone. I'm so confused :(
