This may seem a silly question, but here it is. My sump pump is over 20
years old. It stopped pumping yesterday and after draining the sump manually
and removing this pump I found the problem to be a rusted away pipe near
what appears to be an impeller housing. Whats left of some of the pipe is
rusted to that housing. Considering everything, I'm replacing the pump with
something new. What I have is a pedestal type, and over the last few years
I've spent too much time fiddling with the float and it's guides.

Can I replace this style with a submersible one? From photos they seem more
compact and the float seems simpler.
TIA,
Gerry
