Are sink repair traps okay to use or do they go against code? I thought if I posted here I might be able to get some answers especially since this is such a great and informative site. I am currently using one on a bathroom sink because the previous j-bend had developed a really bad leak. Unfortunately, I do not think I can use a regular p-trap on this sink again because the old chrome trap arm is soldered quite far into the drain stub out. I guess I have what you would call a brass solder bushing. If I try to get the rest of the old trap arm out of the stub out I will end up losing the stub out which is soldered itself into a pipe in the wall which I do not have access to. It will be difficult for me to open the wall because the sink, which is a wall hung sink, is very close to where I would need to open the wall so I might have to remove the sink to work behind the wall and I really do not want to have to do that if possible. So that's why I want to know if it's okay that I'm using a sink repair trap. Basically the current setup is I have a j-bend attached to the tailpiece and a 90 degree elbow attached to the bend and part of the old chrome trap arm. It has not leaked at all and is draining fine. However, I plan on doing some work on the pop up assembly on this sink so I will need to remove the sink repair trap from it. And if it's not okay that I'm using it I would like to know so that when I do work on the pop up assembly I can get the right kind of p-trap on the sink as well. Any information you can provide me would be greatly appreciated. Thanks.
