I recently bought a foreclosed house in Fla. that I plan to live in once my Pa house is sold. I have a few pool issues to deal with but I thought I'd start with the obvious leak in the top of the pump between the seal plate and the main pump housing. I downloaded the manual and see there's a gasket that must be leaking. Should I replace anything else while I have it apart or leave everything else alone? I assume the pump is 10yrs old.
