Basement Laundry rough-in help

Author: NubeDIYplumb (NC)

I am in the process of relocating a laundry room to the basement in a house I just bought. The previous owners had moved the laundry from the basement to a spare bedroom upstairs. The standpipe that was left in the basement and the pipes through the cement floor are all 1 1/2" abs pipe. Should I plumb my remodeled laundry all in 1 & 1/2 pipe, or 2" with a reducer where the pipe exits the cement? Any and all advice is appreciated.

Author: packy (MA) no... you never want to reduce the flow of a drain. keep it the same but do cut it and add a cleanout fitting for the future. also, while you have it open, run a snake wire into it and then flush it well with a garden hose to make sure you start with a nice clean pipe.

Thanks for the information
Author: NubeDIYplumb (NC) Thanks for the information. I’ll keep all the laundry at 1 1/2”. It’s either that or cut out 15 feet of concrete floor. Edited 1 times.
