I hope it's okay to ask this question and that maybe someone can save
me the cost of calling a plumber.  I read somewhere that borax is good
for cleaning the toilet and I poured some into the toilet bowl.  It was
an old box of borax and instead of flowing out of the box, it came out
in largish chunks.  After an hour or so the chunks didn't dissolve.  I
flushed the toilet and everything went down.  But now when I flush the
toilet, it takes awhile for the water to empty out.  I assume the
chunks of borax are stuck in the pipes somewhere.  I'm wondering if
very hot or even boiling water would dissolve the borax and if I tried
that, would I damage the toilet? I have a plunger, but not sure I have
enough strength to use it properly. I'm going to bed now.  If I'm
lucky, maybe it will all dissolve overnight.
