When you pull the plug on your tub you expect the water to drain, however sometimes it drains so slow you think it’s hardly draining at all. Before you call a plumber there are a couple of things you can try yourself. First of all, remove the drain cap, as demonstrated in this video, and remove any hair or other materials you can see. If that doesn’t work you can try to clean the drain with baking soda and vinegar. If these don’t help your problem it is probably time to call in a plumber.
