this is fun !
what i would do is cut the drain that goes into your sump either slightly above the water line in your sump or just at the water line.
the problem is the water in your sump is creating back pressure on your drain line. it could also be the reason you had to get so nuts with the durso. cut it 1/2" above the waterline and place a filter sock over it.
*this is just a guess* MR members please correct me if im wrong!
oh yea... thats a wierd durso..wtf...
