I would like to have a floor drain in my hall so it's easier to wash the floors
I have a radiant floor in a 4" slab. I had the concrete guy leave a 12x12 opening where I intend to put a floor drain in. I can see the 3" Pvc drain crossing under a corner of the opening but just barely.
It's not much to work with but if I cut a section of the 3" drain out by working under the drain and cutting upward toward the bottom of the slab, removing about 6", I figure I can attach a tight elbow on each end, then attach a trap on the end where the water comes in from the laundry, then attach a verticle T with 1 end coming straight up flush with the floor, (where the the floor drain is visible) and the other T end attaching to the water going out.
I cannot cut any of the slab for fear of hitting a radiant line. So all the work has to be done from the 12x12 hole to access the drain line.
Have I forgotten anything?
