It looks like my pump is on it's last legs and I'm not exactly sure how to figure out the maximum size pump I can put in.
I know it has to do with the size of your sand filter....right?
I have a 26 inch sand filter (see sig line)
The reason I ask is I have a brand new 2 hp Challenger pump sitting in my garage, two of them actually. Long story.
Anyway, any advise would be greatly appreciated.
