Issue Description:

Hi,

Not sure if this is one for you or Boni. I have a TiCo smeltery set up to turn testificates into liquid emeralds. I have some liquid copper in the smeltery to do the killing and an RFTools timer set to periodically pump the copper out and back in again to get it back on the top layer so the emeralds can be poured out.

I've tried with Enderfluid and Pressurised conduits. If I pump the copper back into the same Smeltery Drain that I'm using to extract it, the copper frequently vanishes. If I pump it into a different smeltery drain, there's no problem.

Obviously just a minor issue since I've got an easy workaround. Thanks!
