I have read about the use of 2' vs 2.5" PVC when hard plumbing pumps and filters. I don't understand how I get to choose. Wouldn't I need to use what ever size is dictated by the ports on the equipment?
I know I used adapters on the SandPro to connect to the intex plunger valves. But we're only talking like a .25" difference.
If the pump and filter have 1.5" ports, how would it benefit me to go to 2" or 2.5" piping. I'm picturing bottlenecking / higher pressure at one end and low pressure on the other.
Kind of like a highway going from 2 lanes to 4 , pressure drops. Then abruptly returns to 2 lanes, pressure builds. Then finally releases into 4 lanes, lower pressure again, then thru the final 2 lane restrictive gate (this would be the return), higher pressure. Am I anywhere near correct? Is it that final push thru the return (causing better circulation) that we like?
In layman's terms please. I'm no plumber.
