Bilge pumps

I''ve got a Rule 3700 submersible pump in my deep bilge which is not easily accessible. If it''s not the switch, it''s the pump that''s acting up. I pulled, cleaned and replaced the pump and it worked for about 2 weeks. Nothing seems out of the ordinary; not clogged but sounds like it''s cavitating when it''s not working. The discharge has to pump 5'' of head and 25'' long.
This is my first experience with submersibles and was wondering if it were possible to replace it with a diaphragm hooked to the float switch. It would mean a world of difference when it came to maintenance.
What would you recommend? Thanks, Oz
