I have a sliding trash can drawer that would just fit under my sink, were it not for the angle of the plumbing coming out of the sink trap. I could fit the can if the drain pipe—rather than going diagonally from the trap to the exit in the back of the cabinet—went straight to the back of the cabinet, made a right angle turn along the back wall, and then another right angle turn back into the hole.
I know nothing about plumbing, though. What do I need to know before doing this project, and what parts will I need? (I have a hacksaw for cutting pipe.) Is there an issue with adding right angle turns, or anything like that?
This seems simple but I also know that there are some plumbing jobs that must be done by licensed technicians—is this one of them for some reason?
