plumb with pvc. As for the two holes there are several things you can do. You can have it drop to a fuge and the other to your sump. You can also buy a y however you will have to make sure the two ends are 1 inch that goes to a 2 inch. But if you ask me that is a lot of pipe. My 1 inch pipe drops 700gph.
