My kitchen sink is emptying very slowly. The pipes under the sink are clear. So the blockage must be somewhere in the pipe from the wall on. Unfortunately the curved pieces of pipe are in the way and I need to remove them.
Guessing from what I removed with a knife at the point pointed by the three arrows, it is glued together with silicone but when I attempted to remove it, it didn't budge :(
I don't want to force it and break something. Any suggestions on how to get it unstuck?
EDIT: Fixed picture as it was not clear. Also, should clarify, I am trying to separate the grey piece from the one coming out of the wall.
