I recently had a plumber cut the concrete in the basement to install a sink, disposal, and dish washer drain to connect to a sewage pit with an ejector pump.
After the pipe was installed, I noticed that he had put in 1 1/2 pipe rather than 2 inch. He told me that the 1 1/2 was adequate for the 8 foot drain length.
My understanding is that 2 inch is required under concrete by code.
My real concern is if 1 1/2 inch will handle the load.
