We have bought a new sink to replace our existing one. The problem is that the new one is 2" deeper to the bottom of the drain. Under the drain, there is a T where the other side of the sink drain come in, and below that a piece that has a nipple for the dishwasher hose. Neither of these are long enough to take out the 2". Right below these, is the trap. My question is - if I want to keep everything else as it is, can I add the 2" between the other (exit) side of the trap and the drain pipe going to the main drain line without any problems? Thanks.
