The water came out but much slower than you had intended. Upon leaving the building, you somehow managed to accidentally shoot or smash the glass door without noticing. The DI climbed out, found a replacement door somewhere and then replaced the smashed door from the inside, taking some kind of escape tool with him. He then used the escape tool to break the glass. The DI left a puddle in the ring room, which the woman slipped on, had a heart attack then landed on the puddle so her clothes could soak it up.
