What do I need to do to move a rough-in in my basement floor?
Question:I'm going to finish the basement with help from family members who know more than I. We start framing in a couple weeks but the rough-in for the toilet needs to move about 4 feet. It's pvc in a 4" concrete floor.
Answers:
Do as they are saying above...cutting the concrete. Make sure that the most angle you have is a 45. You can't use any 90's on this like except the one that the toilet sits on. After that it's 45's. One more thing, make sure you're 12 inches from the FINISHED wall with your toilet mount. As an example, if your framing with 2X4's for the basement wall you'll need 3.5" for the wall PLUS any space behind it, normally an inch or so. Then you also need to leave room for the drywall. So the minimum space from the concrete wall is 16". That's with no space behind the framed wall. If you space your framed wall out 1' you'll need to center your flange on 17"
you need to break out or cut the concrete slab in the area you wish ti move it to. make enough room to get to toilet bend and fittings you can use askilsaw to score cut area prior to breaking out with sledge hammmer( be sure to use safety glasses and dust mask) if the line is cast iron you should find a screw clamp fitting remove toilet bend and add pipe as necesary to relocate if pipe is plastic cut with saw and add glue on coupling extend line as necessary , backfill trench mix up some concrete and repair floor
Buy a diamond blade for your circular saw and saw a 12" wide path from where the toilet riser is now to where you want it. Break out the concrete with a sledge or rented hammer, electric is preferred unless you have a big air compressor. Run the pipe from the old riser to where the new one is wanted sloping it at 1/4" per foot. I recommend a new stainless steel floor flange, one with the end on the pipe to keep stuff out until you place the toilet on top.
first you'll have to rent an electric jack hammer to get rid of the cement. map out the area you want to cut out and remove enough cement to allow yourself room to work with the pipe after your done assembling the new section of pipe pour cement in the cut out area and smooth it out with a piece of 2by 4 when using the jackhammer use the pointed bit and cut in at an angle and rock the jackhammer back and forth so it doesn't get stuck
