I'm re-doing all my plumbing, ordered 2" multiple port valve to replace my current 1.5" I will have all piping redone in 2" but I was looking at the specs of the pump I ordered and I'm confused, it shows pump pipe size of 2" but port size of 1.5".
How does port size and pipe size differ? I just want to mark sure I'm getting the full advantage of 2" plumbing with this unit.
