RSDB help

[anomie]

Hello all! I was wondering if I could ask for a little help. I'm trying to plump my RDSB and have run into a few problems with my plumbing. I have used 1/2 bulkheads with an mj1200 to feed the bucket. My main problem is that the water isn't draining out as fast as it is being pumped in and overflows. When the lid is on tight, it works well until I lift the outlet hose higher than the bucket which causes leaks around the lid. I'm gussing pressure within the bucket is helping at this point to force the water out. I was trying to similate my sump height by lifting the hose. I'm at a loss when it comes to plumbing which is why I had a professional help me with my tank's intial installation.


Do I need a bigger bulkhead for the outlet? Should the outlet be lower than the inlet? Any tips? What am I doing wrong?

Thank you for looking and trying to help me out.
