I have to get a sewer pipe replaced and it is located in a tight space near the ceiling (and electric box and wires and water pipes, etc, etc. and right over my central vac canister. Plumber said he could not use his "whatever neat slicer" so has to actually saw through the cast iron pipe and admits it willbe a big mess. Am putting up plastic over all I can but I have not outside access door to the basement and the only way to get the plastic full of black iron (and probably germs) is to go upstairs through the hall and out the front door or push it through the basement window which is partly underground with a window well around it. Which do you think is the better way to go? It will be all over the sides of the window and in the window well from pushing it out or if he rolls it into itself and takes it out the front door....I know the sewer pipe will have to be taken out through the front door - won't go out the window because of the angle.

What about clean up? He has a shop vac that I BOUGHT a HEPA filter for so it won't go in one end and out the other. However, there is just so much a plumber will do and I don't even know if he will take the plastic with him or leave it for me. ugh. I wouldn't be so worried about it but had a mastectomy and low immune system. Do I have to wash down he basement with bleach before I re-vacuum as he thinks the dust will go right through the plastic but it will be less than if nothing was put up. Hopefully, the dust sticks to the plastic.

Any advice would be helpful.

Has the plumber suggested possibly wrapping the piping with plastic (throw away drop cloth type) and then snaking the line to make sure it is clear and Water Jetting the line using bleach to kill bacteria as the jetter scours the lines clean?

Then when it comes time to remove the cast iron in sections it will be a much cleaner operation.. It will also be easier to install new NH Cast iron

Thank you for responding.

Plumber hasn't said anything at all except it is in a tight spot. It is not a long bad section and it is the one from the kitchen sink and is curved. Even though it is not from the toilet there was a garbage disposal when we moved in that we took out a few years ago. Would it do to pour 10% bleach water down the kitchen drain before he comes that morning? I guess I am more concerned about the fact he can't use his tool that cuts right through and doesn't make a big dust mess like he says it will with the saw or grinder or whatever he has to use because of the tight spot. I had a toilet leak a few years back and it was an old toilet so the plumber then had to cut the flange to make the newer toilet fit and since the door was off the bathroom as we had to have the floor ripped out I put up 4 mill plastic in the doorway and taped it tightly and there was still black dust on the walls in the hall and the bathroom was unbelievable. I just cleaned it all up and didn't worry about it but I was healthy then. Maybe I am overreacting but I was told esp. since there was a garbage disposal the pipe is still bad even though it is not a toilet sewer pipe. I am being very careful not to pour boiling water in the sink or use bleach now - I just spray the sink with Clorox Clean Up as it is not dripping yet but in bad shape so maybe if I save the bleach water for last -- hopefully -- please let me know. Also with your experience would using my central vac (canister right under that sewer pipe) after he vacuums take care of the dust. I just can not wash down the basement in my condition and have no one to help me. There is an open "shaft" from the basement to the attic right in that area that has water pipes and electric wires running across the opening and I can't close it up - also openings to the back of the shower in the downstairs bathroom. I will be putting 2 mill plastic up over these the best I can. Other than that I guess I have to trust the plumber.

Thanks for any encouragement you can give me.

There are many tools available for close quarters cutting .

The kitchen sink waste line is normally 2" some places allow 11/2

A Lenox carbide blade does wonders when cutting CI and there are many type of cast iron cutters that allow a pipe to be cut with 1" space around it from 11/2" - 6" then there are snap cutters of various types
