Honestly I'm not sure with management, they claim that it's the building being old and having bad pressure, I pointed out that while that may be true, the pressure didn't drop on the hot water BEFORE they put in the new single handle to replace the old separate hot/cold... there's nothing obvious or the maintenance man would have dealt with it, but he's not a plumber per say so it'll likely be the contractors whenever they come back again to do another bathroom to screw with it
