Sewers

Sewer line replacement/repacking trench? We recently replaced our sewer line and are left with a 2-3 foot high mountain range of dirt in our front yard. Will this go away with settling or do we need to have our plumbers pack it down more before we pay them? The trench was roughly 10 foot deep and the contract said they would smooth it to ground level and mound for settling. Is 2-3 foot of dirt necessary for that? Thanks for the reply.

Cost of sewer line replacement from house to main sewer?

HELP with sewer line replacements!? ok here is the deal. i own a dupex in los angeles an poop and toilet paper was flowing through the releif in the backyard. tried a snake and we ran into tree roots. so we dug up 6 feet of the line and found cracks where roots grew in. dug up 10 to 15 more feet and fund the same. this pipe goes from the rear of the yard down the drive way to the side walk. where it connects to the city the ditch was nearly 6 feet deep. im guessing 200 feet. or so. im wondering how much should i be looking to pay for materials and labor. we will have to break through 70 feet of concrete as well. this old pipe was clay.

where is "behind the curb line" for sewer repair? We are having sewer replacement on our block. Our letter states "As part of this project, the sewer service connection and sewer pipe are to be replaced behind the curb line." Is "behind the curb line" past the curb into the street or past the curb into my yard? It makes a big difference in additional work I will need.

Which is the better material to use to replace a buried section of clay sewer pipe, ABS pipe or cast iron? I have to replace part of a main sewer line. The line is clay. I want to use either ABS pipe or cast iron as the replacement piece for the 8-10 ft section. This will mostly be buried 4 ft underground, with one cleanout sticking out above ground. Apparently both materials are used in such situations: can anyone tell me the merits or demerits of either material?
