I've only been living on my own for 10 months so forgive my naivety!
I just flushed the chain and water started pissing out of the top bit, so I lifted the lid and there's like water spurting out of plastic hole bit?
What do I do?!
If I leave it, I'm not going to wake up to a flood am I?
My brother (housemate) doesn't come home from work til 7am.
