I have a sewer line that runs about 75 feet then I have a 45 degree bend to the rest of the line which is about another 75 feet. 2 questions: first, there is plenty of drop as it is downhill all the way, but can it drop too fast? If so what is the maximum drop I would want? Second, is the 45 degree bend OK? I didn't use a sweep, rather just a short 45.I can switch to a sweep since I haven't yet buried the line.

Thanks for the help!
