There's a recent discussion on all of this, might wanna use the advanced search.
Filter mfrs say it's most efficient when pulling, based on the pump's tendency to emulsify any water in the mix if it's 1st in line. Others claim the centrifugal pump (JK) doesn't emulsify and you'll burn the pump up pulling it thru the FWS.

My kit pulls thru the FWS for 'bout 30k gallons now....... and Jeffery Epstein didn't kill himself.
