Undermount double uneven sink drain pipe is not lined up to p-trap!

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!

Is the drain pipe lower than the bottom of the sink? If it isn't it won't work. Can you post a picture of the situation?

Hi Blue Sky,
You should be able to do this without resorting to flexible pipes. The pipe running between the sinks can be shortened and the trap should be able to be twisted so the down pipe from the drain lines up with trap. Generally the traps aren't glued under the sink so you can loosen the nuts and swing them around to line up. If it is glued you could cut off the existing trap and get a new one at the home center that will give you more flexibility in lining things up.

Good luck. It looks like you figured out how to load pictures to hgtv.com congrats!

Also cut a little off the vertical piece on the left so it is really vertical and so the horizontal piece has a drop slope to the P-trap. You don't want water setting in that horizontal piece.

That plastic drain pipe material is very easy to work with. You can cut it with any fine-tooth saw; smooth the cuts so there are no burrs to catch anything.

Great advice from both Sparky and Bob.

You really first need to get the drain pipes from the bowls set up - connected to each other, with one end straight down, and then make adjustments to the p-trap line to get the connection.

You can do it.

Regards.
