Hi,

Please help me figure out how to fix this botched kitchen sink install. I know that the t-joint should be turned 90 degrees, so that there is a straight shot from sink to p-trap. But how do I fix where the drain enters the wall, looks way too high. Thanks!

For starters your P trap is backwards and you're right from the looks of it it looks like the actual drain in the wall is too high you're going to have to remove that and move it down I suggest going to the Home Depot and getting a kitchen sink install kit it should have all the parts you need.
 
and also make sure that you use all ABS and yeah like Voleti said, get a sink that fits the height making sure that the p trap goes into the lowest point i e the p trap cannot be higher than whats draining
 
and also make sure that you use all ABS

Never use ABS under a kitchen sink unless your homeowners insurance is paid up and you enjoy filing a claim. ABS fails after a few years in kitchen sink installs and causes costly water damage. After you cut in to the wall and lower the wall outlet by at least 6 inches, use tubular drainage pipe to re-plumb.

Is this one of those times where things in Canada and the States are different? Never, ever have I saw or heard of ABS piping or fittings failing in a residential drainage application. Where I'm at, it's all that used in houses. Comercial is PVC of course.

What have you saw that makes you dislike ABS so much? If you don't use it on kitchen sinks, where would you?

Also,me don't use tubular p-traps here. Inspectors won't pass them. I have repaired more leaks on those set ups then I ever will on glued p-traps
 
From my service plumbing experience I have noted a high failure rate on ABS piping attached to kitchen sinks. I believe it to be a result of the very high temperature caustic detergent filled waste water from dishwashers which are usually attached to the kitchen sink plumbing. I am often called to repair these leaks when they occur. Lucrative for me, not so good for the owner of the plumbing. I always use poly slip fit drainage tubing and when installed correctly there should never be a leak and it is easily serviceable.

ABS is still often used by plumbers in my area. I was working with a very experienced journeyman last year and he was using solvent welded ABS on a kitchen sink install. When I questioned his decision, he told me he knew of the problems I mentioned but his old bosses had trained him to use ABS so they could guarantee a follow-up call 10 years down the line to repair the deteriorated pipe. I choose not to work that way.
 
I always use abs with trap adaptors and have never had an issue. All my guys do the same thing. Have seen abs outlast the basket strainers. It's easy to take apart and clean by removing trap adaptors and union on p trap.
 
Has there been a new sink installed? The drain doesn't look super high in reference to the base of the cabinet. Has a Deeper sink been installed? This would cause an issue making the connections. A shallower sink may resolve problem.
