water everywhere

That's right the title is correct. Last night at approximately 11:40 in the PM--the drain valve on our water heater snapped after colliding with a picture frame. Water then proceeded to EXPLODE everywhere in our office. After about 1 minute I figured out how to turn the pressure off and there was about 10 gallons of standing water on the floor. I proceeded to call a friend and basically demanding a wet vac. Luckily he was there within 20 minutes and we were able to drain the rest of the water out of the tank, and then focus on the floor. We went to bed about 4:30 AM exhausted and dirty because we couldnt shower! The good news is we can't shower until MONDAY--Maintenance was like yeah can't fix this till monday--WE CAN'T RUN ANY WATER BECAUSE IT LEAKS OUT OF THE TANK.
That's all for now
