yes, the 1.5 hp pump is the one that came with the pool. The original sand filter cracked so we replaced it with the one we have now (was a used one from a person in community). It would save me money to just replace the control valve (this time the control valve is cracked but not the container that holds the sand) but the label on the sand filter is long gone so I would have no ideal which brand of control valve to order. Thanks for all your patience and help!

So here is the pump and filter I picked out to go together. The pump is 1hp, 2 speed Hayward. the sand filter is 21" (200lb) also a Hayward. Does that seem about right? The 1hp combos I looked at had like a 100lb sand filter with them so this is twice as big....

Weirdly this ends up being $90 cheaper than ordering one of the combos and its a bigger sand filter..................
