Any plumbers around here?

[LilBastage]

I want to remove our basement toilet and add a utility sink using the cold water supply. My only problem is with the drain. All the basement drains go to a sump where it's all chopped up and pumped to the septic outdoors.

Is there any way I can convert the plastic toilet waste line to accept the plumbing for the utility sink drain? It's a shared line with the shower and floor drain in the sauna, I believe. I REALLY don't want to have to start busting concrete, so if that's the case I'll need to think of something else.

Thanks.

Technically, there's no reason why you shouldn't be able to do that, it's just a matter of figuring out how to do it with the least number of parts in a semi-attractive way. When you say 'plastic toilet waste line', do you mean ABS pipe? It should be 3 or 4" black ABS if it's like most houses. If so, you only really need to do a couple of things:
1) Remove the toilet flange, if it's still on there. This may be bolted into your cement to keep the toilet from rocking, and glued to the pipe. This is easier said than done, but it should be possible.
2) Glue a reducing bushing into the pipe, (which is hopefully ABS?!) of the appropriate size, using ABS glue. You're trying to get from 4" or 3" to 1.5" which is the size of your utility sink drain, so you may need to make this change in a couple of steps, with reducing bushings, or reducing couplings.
3) Once you've made it down to 1.5", you'll just need a part called a trap adapter, which will make the transition from your pipes in the ground, to the drain piping of your utility sink. This part will glue into the ABS, and compress onto the thinner pipe of your S-Trap.
4) You may need to grab an S-trap kit from your local home improvement store, in addition to the other parts I mentioned. Most of the time they'll try to give you a P-trap (that thing your wife makes you take apart when she loses her wedding ring down the drain), but P-traps are for when you want to connect to your drain through the wall, S-traps are for connecting out the floor.

All this should cost you less than twenty dollars, and shouldn't take too long, with the exception of getting the toilet flange off, which can be a bitch. I however take no responsibility if your basement floods with sink water, or anything like that, so caveat emptor. I hope that answered your question.

Thanks for the help. With this response and a couple of PMs, I think I can handle the situation.
