Hey there. I recently upgraded to a Waterbox 220.6 that has a manifold built into the preset plumbing. The manifold has connections for 1/2" NPT. Problem I'm running into is that my AquaUV uses 3/4" tubing. I for the life of my cannot figure out what to do about this. Google searches and the LFS both failed to turn up a 1/2"NPT & 3/4" barb. I really don't want to run this on a pump as the Waterbox sump is severely lacking in space.. I have nowhere to put the thing. Any thoughts?
