PVC DWV "disassemble" to add in new line

I have an old house with a new building sewer through basement wall. Doing major changes/renovation inside so all pluming will be replaced.

I would like to tap into the new building sewer in the basement without having to redo any more of it than necessary. Unfortunately the fittings are all very close together with only a enough of a pipe stub to join them together. To tap into the building sewer with a the new building drain I will either need to "disassemble" the exising setup a little and add in my new drain or be forced to cut the line outside the house near the cleanout and put in new pipe/fittings through the wall and into the basement to connect to the new building drain. I could do this, but there is enough to do already and I'm trying to avoid having to dig the hole, etc.

Is there a way to take apart a solvent welded PVC joint at a fitting so a new pipe/fitting can be solvent welded in?

Thanks,

Joel

pipe

No, and even if there were you would still have to have enough movement in the piping to slide the pipes out of the fitting and then into the new fitting. There are probably several ways to do what you want to without digging, but you might need a plumber to decide the best way is.

Oh well

Thanks HJ.

That's what I thought the answer was, but I thought I would ask anyway.

The easiest and cheapest way I know of to splice into a bunch of fittings joined too closely together is with this new fitting for PVC and ABS: http://www.afittingcompany.com

overfitting

You still need room to spread the pipes if it is not at a corner, and also need a minimum of pipe between the existing fittings.
