Can I place kitchen sink 3' from plumbing?
My kitchen sink sits right in a corner. I'm getting a new sink and adding some cabinets and counter perpendicular and to the right of the current sink placement. I want to move the sink onto this new stretch of counter on the right. To get it out of the corner, I can put the sink toward the right side of a blind corner cabinet and run the plumbing lengthwise through the cabinet. Using this cabinet would leave me access to the wall on the left (skinny end of the cabinet) where the supply lines and drain are located.
My big concern is that the main drain and P-trap would now be about 30" from where the waste pipe goes into the wall instead of the current sink's 12". Likewise, the faucet will be about 20+ inches further from the supply valves. I'm okay on sink depth versus waste pipe height.
I believe code allows for a pretty long run of waste pipe, but do you see any practical problems with this? I'd rather not go to the expense of moving plumbing if I can avoid it, but I want to make sure it really works. It would be a lot harder to change after the cabinets go in!
My second concern is the access if I keep the plumbing on the skinny end of the 48" blind corner cabinet. The person working on it would have to stick her head and arms into a 24" wide opening, and reach 24" to the valves, etc. Would any sane plumber walk off the job when he sees this access situation?
