Installation Of Drainage Pipes
AryanConstructions

Hi. I am replacing the old cast iron drain pipes with pvc pipes but the connection to the main sewer from my house is at a higher level than my already of laid pipes I cannot raise the level of the pipes as that would mean redoing my entire kitchen from the base as a pipe is going under my kitchen. also i have a problem of seepage in walls and if i backfill or do any kind of filling to reach the sewer pipe then my foundation and part of my house goes under the soil. Currently the drain is at four feet depth and if i put my sewer pipe at the drain level so that all water gets drained then i will have to cut into the main drain at 2 ft from top so my pipe will be just 2 ft from bottom of main drain. Is it safe to do that as i do not want any water from the drain entering my house.

How was your old CI drain pipe set up? Was it draining properly?
You should have placed your new pipe in exactly the same height/location.

I can't give you more without actually seeing what you have. My advice, call 2 or 3 local plumbers who install drain lines for their opinions.

...And another thing: check if a new main drain line has to be inspected in your town. If it does, then pull a permit.

You should have started from where the sewer line entered the home. At this point your only other option is to install a sewerage pump with a tank. (which would be a totally stupid thing to do)

AMEN! Whenever you're re-diong any entire system you either follow the original or you design the new system to work with whatever it interfaces with. Assume nothing, discover everything, plan thoroughly, then execute the plan. You've got a lot of re-do ahead of you- experience is a hard but fair teacher.
