My downstairs bathroom sits over a utility room in the basement, and you
can see the pipes that go to and from the toilet in that room. A few
months ago, I noticed water on the floor and thought I had a leak. So, I
had my roommate go to the bathroom and flush. Here's what happened:

Toilet flush.... everything OK
Tank starts filling.... starts leaking into the utiltiy room like crazy
Tank completes filling.... leaking totally stops

I found it strange that the leak only occurred when the toiled tank was
filling. Once it was full all leaking stopped. Since it did not leak
during the flush, I assume that the water was clean. It seemed strange
and didn't know how to diagnose it.

Any ideas?

It gets even more complicated:

So, I made that bathroom off limits until I could find a plumber (which I
never did), but my roommate accidentally flushed the toliet there today.
Since I was downstairs, I ran to check out the leaking. Well, guess what?
No more leak. Now I'm really confused, and how am I going to ask a
plumber to fix a leak that no longer exists?

I am asusuming that the leak stop is only temporary, either that or the
plumbing gods have smiled on me. Any thoughts, ideas, or opinions are
greatly appreciated!

Thanks,

Mike

possibility there is a hose that should be clamped onto the overflow tube in
the tank, but the hose has become loose and is spraying water up and it's
leaking out the top of the tank, try removing the cover and checking it

here's a diagram of what you should see inside the tank, the overflow tube
is the second white rectangle from the left inside the blue area (tank
water), the hose comes in from the top (and should be clamped onto the side
of the overflow tube)...be careful putting pressure on the overflow tube,
they can break easily at the base, requiring the whole assembly be replaced
