    How to move a water closet drain 4 feet on a 2nd flloor
    I have searched this site and found what I think is the answer to my question, but I still am not quite sure. I am remodeling my master bath on the second floor of my home. I need to move my toilet approximately 4 feet from it's current location. The current drain for th toilet goes horizontally down to the basement through a wall. My question is: Is there enough room between the floor and the 1st floor ceiling (12"') to accomplish this?

    Sure, there is enough space to move it 4'. Don't worry about vertical part. Cut your existing toilet pipe between hubs, install coupling and extend in any direction you wish. Then, install "toilet bend", "closet ring" and you are finished. Don't worry about moving vent or installing new one. Since you moving it only 4' away, existing drain will vent your toilet just fine.

    What type of pipes do you have? PVC, ABS or C.I.

    Hi Milo:

    Thanks for the quick response. It seems too easy. I have all PVC. My home is about 20 years old.

    To be clear: Is there enough room to put in (2) 45 degree bends and a straight pipe within the distance between the 1st fllor ceiling and the 2nd floor ?

    Yes, 12" ( actually 11.5"), the size of your joists, is wide enough for moving your toilet pipe.

    PVC is easy to work with. HD and Lowe's carry PVC pipe and fittings.

    Thanks again!

    You've made my day! I was envisioning having to run a new pipe through the wall because I though that the pipe needed a strighter run to eliminate clogs.

    I'm ready to go.

    Thank you

    3" pipe should have 1/4" slope per foot . 4" pipe should have 1/8" of slope per foot.

    Leave existing horizontal to vertical connection the way it is. Just attach to it. Extend new pipe and bends to your new location. Glue all together.


    If you have to horizontally penetrate ceiling joists with your new pipe than Drill. If you don't have such a large drill bit and have to cut, than pre-drill with small drill and neatly enlarge with sawzall to the required size.
