[Hayakawa, Yoshimura, Yamaguchi, Takahashi.m]
We turned on Y-arm water pumps (Y1000 at 11:00 and Y2300 No.2 at 11:15).
Now all three water pumps are working (Y2300 No.1, 2, and Y1000 ).
There was some flooding from Y1600 to Y2300 in the morning, but by around noon, it was fine.
The room temperature in the Y-end may be lower because the water from pump No.2 goes through the Y-end.
