I need to replace a Pentair Multiport Valve (p/n 27-2120). I can't find this P/N on the site. Is there another Pentair Multiport valve to replace mine?

A  Answered on 4/28/2013 by InyoPools Product Specialist Patrick P.

I believe the part number 272120 is the sticker part number for the valve you're looking for. The valve number you're looking for should be SM1-PP2, which is meant for DE filters.

Will this valve fit onto a PacFab Nautilus DE filter model number NS 36?

Hello Mike - The 4715-0 valve will fit the Nautilus NS36.

Will this match, as replacement for my American Products valve ( do not know model number ), as the filter, is Titan RPM model 188552 DE filter.

Hi Len, The 1 1/2" P.F. D.E. Valve (SM1-PP2) can work with your Titan RPM model 188552 D.E. Filter.

Hi Robert, yes this multiport valve is compatble with the Pentair Nautilus FNS D.E filter.

Will this work with fns plus?
