Will this fit a DE7220?
My parts diagram shows the number as SP0410X5025 (note that it ends in 5 instead of the "s" you show above.

Will this backwash valve fit my Nautilus 46 DE filter I installed in November 1991?

Hi, Rad. This Hayward Slide Valve will not fit the Nautilus DE Filter. The Pentair Push Pull Valves can be used depending on which Nautilus Filter you have.

Correction. My Nautilus DE filter is the NS-48 model. Is this backwash valve compatible?

Hi, Charles. This valve can be used with selected Hayward filters. However, NSS-48 is not a Hayward model that I'm familiar with. Please double check the make and model of your unit and let us know so that we can locate the correct valve.

Hi David, No this is NOT the correct replacement valve for the HRPB30 Sand Filter. You will require this HRPB30 Slide Valve

Will this fit my DE3620? (old manual calls for a SP0410X5025, for all intents and purposes this appears to be the same 2" part)
