Floor drain and S-Trap q's
This is related to a replacement basement sink

What is the best way to attach an S-Trap to a floor drain that is not coming out the floor straight?

The floor drain is iron pipe, I removed the old metal cleanout and chrome/brass s-trap but left the metal 1-1/2" nipple on the iron "hub". (Looks like a reducer with female threads was leaded into the hub with a 1-1/2" nipple attached)

Here is what I did: Attached a 1-1/2" threaded male adapter to the nipple(female thread/coupling). Then a 1-1/2" T fitting with a male adapter/cleanout plug and a 1-1/2" compression type fitting on the top.
Then installed a S-Trap, seen here: .

The s-trap leaked at the middle s-trap joint(the slip joint where the 2 U shapes meet), so I dissasembled it, added joint compound to the middle joint and made that up first, then tightened the other joints.

This stopped the leak but how long is it going to last? The drain being slightly bent coming out of the floor is an issue, IMO tightening the pipe that went to the drain first was not allowing the middle joint to seat properly.

Any thoughts on this or better methods?

Well since an S trap is not even legal anymore you off to a bad start.
Got any pictures of what your trying to do?r

Why illegal?

I have no pics at the moment, its in an old house and basically replacing the the old with new.

Is there even a vent for this sink?
Without a picture you get lots of questions and fewer ansewers.
It has to do with the traps getting sucked dry when using a S trap.

Ill take some pics and post them today

As far as venting, I would say no...the house is probably early 1940's and the original setup was basically exactly as what I replaced.

I thought the same thing myself, no vent piping seemed strange, so i just replaced the old with new.

If we are talking about the replacement of an existing S-trap, in an assembly that dates to the '40's, then legality should not be an issue what-so-ever
