A question if someone could help with an answer.
I need to lower my kitchen sink drain in the wall. To handle a little deeper sink. But I found this pic on a website. It looks like a way to do it without ever having to lower a drain.
The P trap is just taller on the output side.
I wanted advice from people here. If this meets code or are there any cons to doing it this way. Thanks for any advice.

You might get an answer if you post a clear photo of your sink and drain as it looks now, and describe exactly what change you want to make based on that photo.

My understanding is if you reverse the J-bend to make the P-trap higher to meet the wall connection the down side is:
(1) Depends on how much higher, you could raise it by an amount such that your garbage disposer is always going to be filled with some water which may lead to premature corrosion;
(2) The J Bend's "new" inlet side (which used to be the outlet side) will be very shallow so your tailpiece from the sink cannot really insert adequately into that for a good connection. If you have stuff stored in the sink cabinet like bleach, detergent, dozens of jars of other things it is very easy to knock that connection loose to cause a leak.
There are low inlet J bends available you might look into as another option.
