Toilet vs Floor drain??


Right now we have a main 4" cast iron sewer pipe running through our basement floor. The very last fixture on the run is a toilet. Can I remove the toilet, replace the final 90 degree elbow with a tee and replace the toilet in the same place, then extend the line a couple feet further and plumb in a floor drain?? (with p-trap of course)

Thanks in advance!

I can't see why not.

But you have to account for the venting. You THINK the last fitting might be an elbow? in the fact you presume that it turns upward to serve the toilet? But perhaps it is not an elbow. Perhaps the toilet already is in a wide sweep tee, and behind the tolet is the vent stack?

But anyway; if you tap into the 4 inch that serves the toilet to add pipe going to some other fixture..that in it's own right should be okay. Just search for the vent.
