has anyone actually done it successfully? I have a very small sump pit
about 15" wide by 18" deep and would like a smaller pump so it will
cycle less often. I only need it from Feb-April but we sometimes get
some big rainstorms (5+ inches) here in CT so I'm just worried that
the 1/3 hp (40gpm 10 ft lift) wont keep up with the 1/2 hp (53gpm -
10 ft lift).

The ONLY reason to keep your 1/2 hp pump is that during a very, very heavy
rain it runs more than a few minutes at a time and runs more than 1/2 (more
or less) of the time.

Your 1/3 hp pump is clearly more efficient than the 1/2 hp pump.
