The problem I'm having is one, brand new it wouldn't start and tossed an error on the controller. I had to actually disassemble the pump and use some Molykote grease just to get it to start. Now that was 2 months ago. I lubed it up and stowed it away till my WB showed up last week and wouldn't you know the pump tried twice to spin up and finally it ran. Now the issue is my center sump chamber constantly rises and drops constantly as if the pump isn't able to remain a constant. It triggers my ATO. I've even removed the socks and all filter media and it still does it. So that's why I'm considering going with the Sicce syncra SDC 3.0
I'm pretty sure it'll fit but I'm going to be sure I can return it if it doesn't.
