My home is 3 years old and in the master bathroom I have a dual sink, one drains fine and the other is very slow. I have taken the U trap off and snaked about 18 foot of the line finding no clog and as soon as I run water again it drains slow and I know the pipe is empty.
I looked at the vent pipes and they looked okay. Do you have any suggestions of what to try next?
