On Monday night we had a big leak in the Education Library, coming down the wall in the entrance to the Reader/School Journal Room on the ground floor. We rang security, and they came over fairly promptly, then they called in a plumber who isolated the problem after a while. He had to open up a wall over by the videos to access the pipe with the leak. He said he will be back tomorrow to fix the problem. The broken sign on one of the upstairs toilets relates to this. There will probably be wet carpet still tomorrow morning.
