I have an above the ground pool that is 22dia. x 4ft tall. My pump has gone out. sf15110 I thought about going to a larger pump. If get a bigger pump do I also need to get a larger sand filter ?

Sorry I didn't see this sooner => NEVER increase pump size, without increasing the filter size.
Virtually ALL above ground pools have oversized pumps and undersized filters. Matched sets, like Intex sells MAY be actually matched, but I don't have data proving that.
Oversized pumps:
push dirt THROUGH sand filters
DAMAGE membranes and grids on DE filters
COLLAPSE filter pleats on cartridge filters.
What most pools need is a bigger FILTER, not a bigger PUMP!
