Omg, what a shocking thread!  What were they thinking?!  I can't even wrap my head around why someone would think that was a good idea?  Did they think the sump went to a floor drain or something??  Some people really don't understand how our tanks work, but wow this is a new level!  
Props to Concept for helping out!  What is the damage?  It sounds like it is mostly going to pull through?  I hope...
