plumbing questions

[hammer1]

since most of use here have a bit more knowledge of hands-on working of things than the common man, i have a plumbing question:

I need to tap into a 3" pve drain line, with either a 1-1/4 or 1-1/2 pvc drain for a sink. Is there any sort of "saddle" type fitting, where i would cust a hole, put a fitting in, and glue some sort of flange around it? or should i cut out a section, put in the tee fitting, and use flexible rubber couplings.
i dont think i have have too much play side-to-side wit the 3 inch drain, but i have not tried, since its not cut.
BTW..the 3" drian is horizontal under the floor, and the sink drain will come across the open bay between the studs, at whatever angle works
thanks

just a cut a reducing tee into it. once you cut the 3" you'll find more movement than you thought you had.

Brian is right. We cut tee's into our cpvc pipe all the time. The bigger the pipe, the harder to spread if it's tight. If it's too tight, go to where it tee's or 90*'s parallel to the joists and stick a 2x4 between the pipe and the joist & use for leverage to pull the joint apart. You will probably need a helper for that though.

Good luck!

Oh, and don't forget to cut your take-out out of the 3" for the 1 1/2 outlet.

i thought it was a given, that two cuts would be made in the 3".

Just a reminder. I've seen experienced people fighting to cut a tee in when they forgot to cut out the take out
