I'm planning on going from an 1 1/2" drain to 1". I suppose I could get by without the h2overflow if I put a gate valve on the main drain and have an emergency drilled. I'm going to run a mag 7 as my return through 3/4" tubing. I'm wondering how I can plumb the mag 7 though as a standard fitting doesn't tighten all the way down on the pump. The body of the pump is slightly in the way
