Are the inlet and outlet connections the same as on my current FNS24? Can I just unscrew the slide valve off my old FNS24 and screw right on to the new FNS PLUS24? Thanks

Hi John, The FNS24  and FNS Plus 24 can use the same multiport valve.

Hello- The biggest pump size I would recommend with the 180006 FNS Plus 24 Sq Ft Filter w/o Valve is a 3/4 HP such as the 011771 Whisperflo Pump 3/4 HP.
