Good Morning Everyone!
This site and the members have taught me so much and have saved me a ton of money, thank you!

I have a question regarding a new pump install to existing plumbing. My suction lines are 1.5 in PVC the pump I purchased is a Pentair 011028 which has 2inch pump connections. My question is should I run 2in pvc from the Pump to the suction lines then use a reducer to mate the 2in to 1.5. Or just run 1.5 to the pump with a 2in to 1.5 threaded slip collar. Or does it matter? Thank you everyone in advance.
