    How to move a floor drain
    I have a floor drain in my laundry room right beside a wall. My sink, washer and dryer are across the room and drain into it via a pipe across the room that just dumps into the hole in the floor. I am looking at finishing my basement (myself) and would like to move the wall in a few feet to make a family room larger on the other side. As it is now I can't move it because the drain will then be outside the laundry room so I would like to bust up the floor, move the drain to the side of the room with the washer and dryer and then move in the wall. How would I go about moving the drain?

    Hi Mom... like you said, bust up the floor, dig down and around pipe and depending on direction the pipe heads underground you will either have to cut it and shorten it or cut it and attach onto it and lengthen the pipe.

    Depending on the age of your house, you may have PVC or ABS (PLASTIC) or you could have cast iron metal pipes/fittings... YOU hope it is plastic!

    Either way, you cut pipe, move pipe/trap to where it goes and that should do it... UNLESS the vent for the floor drain is inside that wall you are moving.. or somewhere nearby and then you will need to relocate that, too. There are distance to floor drain ptrap rules, so if find this pipe let me know how far away it is from the floor drain.

    All in all, you will need a sawzall, piping, fittings, level, shovels, jackhammer or chipping hammer,

    If cast iron, job is harder, will need to ad to above list with no hub clamps, and a saw for cutting cast iron pipe... minimum.

    If you want to do this and are handy.. I say you can do it... we can help you... especially if you have pics.. you can post to this site. Anyway, let me know your thoughts.

    If this helped, please RATE THIS ANSWER. Thank you.

    How would I go about moving the drain?
    Since you didn't say I'm going to assume that you have a older home with cast iron drainage. Correct? Now I need to know if there will be any bends to the new spot or will this be a straight shot? If it's just a few feet then break up the cement over to the new location and cut the floor drain out leaving a few inches of pipe still attached. Now cut a piece of pipe that will attach to the open pipe and the floor5 drain using shielded couplings, (see image). Give the pipe 1/4" slope to the foot and keep the top of the floor drain under the floor line so the floor slopes around it a little. Good luck, Tom

    Only thing is the new drain can be straight across the room but it's got to be 15 feet or more to get to the other side of the room
    Are you concerned about maintaining slope,( around 4") for a 15foot run? If so reduce the fall to 1/8th" slope to the foot. Let bme know your concerns. Regards, Tom
