I accidentally blew up my friends pool filter and am helping him replace it. He had a 31" Hayward sand filter running a 20k gallon pool. From what I understand that is overkill. So we are trying to figure out what would be a good replacement.
We have been looking at a Hayward 24" sand filter but I am worried the pump is too big for it. The pump is a 1.5hp K48M2N110. I haven't had much luck finding out what the GPM is for this pump but looking at newer Hayward models it seems it is probably between 80 and 90 GPM.
My question is, do we have to get the pricier 31" filter or can we run a smaller one with the same pump? Of course suggestions not related to my question are very welcome.
Thanks in advance,
