I've pretty much fixed up my bathroom since moving in. The last bit of annoyance now is this:
Not every time, but every 10 or so flushes, my toilet will run continually. It'll sound like it's water is filling up for about two minutes, then stop for five minutes, then sound like it's filling up again... on repeat. To stop it, I have to go back in and jiggle the handle.
One time I took the lid off the top of the toilet and it looked like it was slowly losing water from the top (or whatever it's called).
Any idea on how to fix this?
