I am just setting up my sump for my new set up and i was looking and originally going to use a mag 18 which has a 3/4 inch inlet. But came into a much better pump for my PM bullet 2 the panworld 100px, and now i have a diamond hole saw and a 3/4" bulk head but a 1" inlet. would i be ok using a 3/4" bulkehead and pvc plumbing into the panworld pump or should i buy a new bit and bulkhead?
