High Flow Submersible Pump Options

[Scythanith]

I have had to replace a Quietone 5000 once after about 4 years of service. It was submersed and then my new sump called for external so I re-plumbed it and in about 4 months its housing cracked (it later fried in my salt mixing pail). Also I have burnt out 2 quietone 800's which I used for odd jobs. Motors were fried.

I think the flow and noise levels were good. I have had issue with restarts after power loss though. Maybe I have to pull it apart for a good cleaning?
