So my lesson learned after moving the poo pipe was that jackhammering concrete isn't all THAT bad, although if one was to do it near a tank they should put up a blast sheild because concrete debris was flying everywhere.

But I think about how it is to cut a linear length of pipe and insert a T fitting into it. You cut the pipe, move the cut pieces apart so that you can wrestle the fitting into it, and then jam the pieces back together. How do you do that when the upstream and downstream sections are still underground? They'll have absolutely no wiggle room... or you'd have to jackhammer the whole pipe out to the endpoint and relay it all the way to the end again.

No thanks.

One laundry sink coming right out of my basement.... guess my 4 piece plumbing permit just became a 3 piece.

it is a PITA to put a T in existing. basically ya you got to hammer out a bunch. BUT, you can get rubber pipe couplings that are sealed with hose clamps. It doesnt need to be the regular PVC joints. So with the rubber couplings on either end, you cut out a section, slide the couplings on either end, set back in place and slide couplings up over the pipe. Not as bad as you think

these are what I'm talking about

I did sort of wonder about those but .. dunno, just doesn't seem as solid as cementing a joint. But I guess when you're in a bind, you do what you have to do ..

Not solid, but they seal really well, AND, your going to be burried in dirt and cemented over, right, so no movement

Tony the fittings for a 3 or 4" pipe usually have a 1" flang on either end.... Just cut the opening for the new tee about 1" shorter than the tee itself and slide the tee all the way to one side and then back on to the other side. You will end up with 1/2" insert on both sides.

Ah ok. Yeah I see. Thanks! If I do decide to go ahead I guess it won't be so bad. It still sounds a whole lot easier to tell the inspector I've decided not to have a sink anymore. What happens after he leaves is ... well .. not his or the city's problem, unless I decide to do something really dumb, which I hope I wouldn't. I figure I can just remove the sink if I ever sell the place.

you can also get expanding pvc joints you cut section of pipe out glue in your t then a piece of pipe on the other side of t then glue on the expansion joint then put your glue on then just pull it out and push it on your pipe that doesnt move . all solid joints.get them at any farm irrigation store or andrew sherets in bc.

Hey Tony, I might be in the city this weekend, I am a plumber by trade. If you want me to take a look, let me know, I am sure we can come up with something that will not involve a lot of work, like hammering up a floor. Just a thought.

Thanks for the offer. I am sort of thinking of just go ahead and doing it and then not having to worry about it. Too bad I didn't come to this conclusion when I already had the jackhammer last weekend, but oh well, at $40 to rent, it could be worse.

I've figured out where the nearest drain vent is to the roof and determined that it is just a vent (ie., not a drain from any upstairs sink). So it won't be too bad to snake a 1.5" line through the ceiling over to it and tie it in.

The main thing is time, my wife works this weekend so I have to find me some babysitters to entertain the kids while I hammer away at the floor. I'm pretty sure the floor drain line runs right underneath the laundry sink so it just needs to come up and then Y-fitting it over to the vent line that will have to snake its way up the wall and through the ceiling. This might be something I can work on during the week after the kids have gone to bed - getting it all roughed in so that all that needs to be done on the weekend is the jackhammering, tie-in, and re-concrete-ing..
