Dual 1in pvc piping return, vectra m1.

[Bugeater281]

I though my pump had a 1inch return(to tank) on it. It’s actually 3/4in. I have a 6ft long tank so I was going to run dual returns. Will this affect flow at all?

I already ordered my 1in black pvc and bulkheads from brs. I’m hoping they will work fine.

The added pipe will cause more head pressure reducing flow.
