I have been rethinking my drain assembly and I need to clarify my plan. So, the tailpipe comes straight down into the ptrap. The ptrap is 8 inches to the right of the waste pipe. After the ptrap, can I use a 45 or 90 elbow or two to connect the extension to the waste pipe? I think by cutting the waste pipe shorter and adding a 45, i should be able to run an extension from the 45 into the ptrap.
I read about code being no more than one slip joint between the ptrap and waste pipe and I am unsure if that applies to what I am trying to do. For what it's worth, although I would be using an angled joint, I am not planning to change the horizontal run from the ptrap to include a vertical section which I think would make an s trap which I have read are illegal.
