If you have a slow draining bathroom sink it may be clogged with build up or hair. Sometimes you can pour liquid plumber or drano in and that will take care of it but sometimes nothing works and it needs to be snaked to clear the pipe. Most sinks can’t be snaked untill you remove the pop up because a snake just won’t fit. Learn how to remove and replace the pop up or to replace an old one from Do It Yourself.
