Removing a sink drain is a relatively simple plumbing task that can be completed in a few minutes with the right tools. The most common type of sink drain is a pop-up drain, which is held in place by a stopper that fits into the drain hole. To remove a pop-up drain, simply pull up on the stopper and the drain will come out. If the stopper is stuck, you can use a pair of pliers to gently pry it loose.
Another type of sink drain is a lift-and-turn drain, which is held in place by a screw that fits into a hole in the drain hole. To remove a lift-and-turn drain, simply unscrew the screw and the drain will come out. If the screw is rusted or stuck, you can use a pair of pliers to gently pry it loose.
