Hello All! I have been a lurker since last year reading all of the great advice and mods that you guys come up with. I am going to put in a Hayward wide mouth skimmer this year and decided to plumb the pool, pump, and sand filter with PVC. My question may have been answered in one of the many very detailed spreadsheets created for proper water flow. I have a Hayward pump that is rated at 70gpm, and I was going to plumb everything with 1 1/2" PVC. Is this going to be too big of pipe? or will I be good?
Thanks for all of the great info, and if someone can point me in the right direction or answer this that would be awesome.
