Does anyone know how to install drain and faucets for triple bowl sink? We have a franke triple bowl with draini on side. Delta faucet is is a three hole contraption: 1-faucet 2-hot cold shut off 3-sprayer. This faucet is soft water. In addition there is a separate line for purified water, and it is hard water. We had a two bowl, but this is confusing. Also, lest I leave something out the center small bowl will have a garbage disposal, and there is a dishwaster attached as well.

Does anyone know how to install this mess? Do we need to add an additional drain? Would it feed into main drain? HELP. Thank you.

 

You need a disposal-with-drain or a regular sink tailpiece in the middle tied together with drains from both sides.
You only need one trap, which will be connected to the main drain pipe.
Connect the trap from the drain nearest the main drain, and 90 or T off the other two above it.
Connect the dishwasher to a tailpiece-with-dw-connection at the drain nearest the dw side, or you can tie it into the disposal dw connection, if that works better. If you use the disposal dw connection, don't forget to tap out the knock-out plug in the disposal with a hammer and screwdriver.
Good luck!
