pump problem...

had a loose connection from the return pump in my sump which caused a bit of
a volcanic reaction when the tubing popped off. yes it was a big mess...
but the only thing I had handy was one of those metal plumbing tape things
that you tighten with a screw. The tubing is too thick to tighten with a
zip tie -- and I'm a girl -- not very "tool' saavy. Anyone tell me what I
can use to replace the metal thing -- I'm afraid the metal will rust and
foul my water -- am I right? thanks
