To do this, take hold of the stopper with your fingers, and try and turn it. If you do not feel any give, or if there are no signs of movement (other than spinning on its axis), then your stopper will require more work.
If the first step worked for you, then congratulations, you have achieved your goal, and you no longer need to follow this guide. However, if your bathroom sink stopper is still wedged tight, then it’s time to progress to the next step.
The third step requires your flashlight. Use this to locate the horizontal plunger rod that connects the strap to the stopper itself. Once you have located this, then look for the rod that connects the vertical strap.
Before you do this though, place the bucket underneath the pipe, just in case there is a back up of water. You don’t want to have a water damaged bathroom floor, and this is something that can stop a minor task becoming a much more time consuming.
If you have followed these steps correctly, then you should be able to release and remove the bathroom sink stopper from beneath the sink, and you should be able pull it out without any issues or resistance.
