I am remodeling a 100-year-old house, adding plumbing for a washing machine and condensing dryer. I'm installing the washing machine and dryer in the basement. In the location where I want it to go, there is a 1 1/2" brass waste pipe coming up vertically from the basement floor, about 3 inches or so. The main waste stack is about 2.75 feet away.
I believe I need to install a tee fitting, connect a waste arm to it, connect a p trap to the waste arm and a standpipe to the p trap ... similar to the below picture (except with a standpipe connected to the p trap and not a sink).
How do I connect the tee fitting to the brass drain pipe? Is a rubber reducing fitting OK?
Is my methodology correct?
The p trap needs to be 2" as per code, is it OK that the brass pipe is only 1 1/2" ?
