Novice speaking - Purchased and started install of new sink, disposal, faucet. The new sink is deeper than the original. After getting some things in place, there are two issues (maybe more) that I do not know how best to resolve - with the main question being is this DIY work?
1. Drain line going into the wall is at the same level as the disposal discharge tube (see image 1). The drain line going into the wall is about 15" from the cabinet floor to center, and the cabinet floor is about 5" above the finished kitchen floor.
2. The left strainer basket is directly over the slip joint, so I can't just simply put the p-trap back in (see image 2).
Thanks very much in advance.
The extension you will need to piece together on the disposal side will be more easily accomplished with glue up pipe than slip joint tubular, but no matter now you do it, you will have a deep trap and it will drain slowly.
Although is seems like a lot of work, you will be better off in the end if you open the wall and lower the san tee .
The proper way is to lower the TY in the wall. The easy way is to reverse the bowl of the trap so the shorter end is on the disposal. This will work with most traps. There are some traps that do not have enough slip on the lower end of the bowl to do this. But if you look around I'm sure you can find one.
A double Y rather than the single one you have would have made the left hand connection easier, and you will probably still have to find one and use it. There are NO traps that make a good connection when reversed. They have to be installed in such a way that there is tension on them so the tailpiece cannot come out of it.
