yeah... I thought of that, but a piece of pvc cut in half and screwed together with a nylon bolt should be pretty safe. Id be more worried about junk from the fuge and I'm not really worried about that either.

It might even be safer to use the pvc glue instead of the nylon bolt. One way or the other, there shouldn't be very much pressure against it, not like the filter floss. I just have to find something that will catch bubbles but allow the water to flow well.
