Hi there
I c you are online and read a few of your posts.I was hoping you could give your opion on something.
I am renoing a bathroom and am putting the bathtub where the vanity war .my question is can I use the 11/4 sink drain for the tub.I know it should be 11/2 but if I could use this 11/4 it would save me hours in labour .it would be vented and about 4 feet from stack .but would love an experts opion .
Hope to hear from you .

Tubs and shower drainhs are nornally roughed a 2 inches to prevent clog and blockages. Anything smaller and you're asking for a clog.
Now, explain to me how a tub that picks up under the floor line can use a lavatory stubout that sets 18 inches off the floor. Regards, Tom

The drain from the sink goes into the wall under the floor to the stack.I was goint to cut and cap the sink line then put a 11/4 t under floor to pick up the new tub.I figured it may be OK the old tub was reduced 11/4 from tub to 11/2 p trap .so its about clogs then not flow rate? Would increasing the drain angle help at all?
p.s sorry about the message I didn't relize it was a different search for each topic .
Think I figured it out now.I am not the most computer literate as I should be srry

No problem for me. I just have to jump around a bit more to answer PMs and E-mails. You can't lay a sanitary tee on its side. Use a wye or a combination wye and eighth bend instead. You can use 1 1/4 to drain your tub but I wouldn't recommend it. If you do I would install a cleanout near the tub trap to be on the safe side. good luck, Tom

Cool thanks for the info .
Would increasing the slope help any? Also does it matter where the tapper happens ?I could run 11/2 from tub to about 1 foot from stck where it would have to reduce to 11/4 .I just can't get my hand any further without some major demo.

Do the above points make any difference.ie slope?and when tapper happenes? just want to be a sure as I can before I start cutting .

Increasing the pitch won't prevent clogs. You can try 1 1/4" if nothing else works but I would install a cleanout next to the trap just to be safe. Regards, Tom
