Main Sewer lin Replacment

I have an Old home with leaking cast iron line and it is underground under the home. I can replace with new ABS above ground but the problem will be where the New meets the old line it will have about a foot drop to mate up. Would you use two 45 degree or what would be the best plan of action. Digging up old line and running in the same trench would take forever not to mention the home has been added on to and it goes under two different footings.


Thanks for any help

try this............
