Hi, we got reversed (80:20, bigger-right side) undermount double sink (Alba sink) but main sink drain to p-trap is not lined up. The sink is 8-9 inch depth, so there is not much room from strainer (main drain sink hole) to p-trap. Do you think we can use a flexible plastic drain from stainer to p-trap? I am not sure anyone has problem? I tried to google for installation of uneven double sink but so far nothing! Any input very much appreciated. The black pipe is old metal pipe (p-trap) and someone suggested to cut the black metal pipe but then how easy to cut solid metal without compromising p-trap? thank you!
