Can I tie my bathroom sink and utility sink drains together? As well as vent?
In the picture you'll see my existing stack that was put in when the house was built for the basement rough-in. (Pay no attention to the hose coming out of the plug, it's a water softener drain that was not done correctly. I'll be taking care of that in another way.)
To the right of this picture i'll be installing a bathroom sink and to the right of that a utility sink.
My questions are:
1. - Can I bring the utility drain over to the bathroom drain and attach with a "T"?
2. - Can I use the existing "Y" in the stack for the drain or should I leave this as a clean out and put a new "Y" above the one in the picture?
3. - Can I again tie the two sinks together in the same manner for a vent and attach further up in the stack?
