I'm trying to figure out how much pressure I would lose if I have a 1" external bulk head and then I reduced it down to 3/4" for the intake of the return pump. On the way up to the DT the 3/4" outlet would switch to a 1" pvc pipe. It would be easier if my return pump has a 1" inlet/outlet but it doesn't. Does it matter?
