Plumbing drain question

[Rick]

I have a reasonably new split bath, with the vanity/sink in one room and tub and toilet in the other. I want to install a very small pedistal sink between the toilet and bathtub. The wall is accessible thru a closet in the next room. Routing supply lines isnt't a problem. The drain pipe, though, is not easily accessible as it runs too far from the wall, under the floor. The only part I can tie the new sink into is the straight piece of PVC that connects the bathtub overflow to the tub drain. Is it OK to install a T there to drain the sink? The sink would have its own trap, but the wastewater would also go thru the tub trap. Thanks.

No codes or standards permit such a connection. You will have to access the drain line after the tub trap and also meet the standards for venting to make a proper connection. You may need advice for your particular situation from someone who can actually see and evaluate it on site.
