How to unclog your bathtub drain? So you’re gonna need a standard Phillips head screwdriver. Take your tub stopper and either this top will screw off or you can unscrew the whole thing. But some tub stoppers have a set screw underneath. Find that set screw with your finger and try to locate it and give it a couple turns counterclockwise while pulling up. Then this stopper will come right off and there’s the set screw don’t lose that. Here’s the reason it’s clogged is so much hair stuck. so we’ve taken off the tub stopper and the drain crossbars in here and that’s where this hair is catching. After pulling all that nasty hair out and this is what the drain looks like nice and clean. The next step is to pour some baking soda and vinegar to clear out the p-trap. Two tablespoons will do and then take some vinegar. Just letting that baking soda and vinegar reaction go through the peach wrap and push all that gunk through your pipes. To avoid hair building upon these crossbars you can go to drain funnel. Drain funnel and what it does is it bypasses these bars by funneling all the hair and water towards one quadrant of the drain. To install it is located one of these back holes and then push the drain funnel in. That it sits nice and snug in your drain and it fits all standard 1.5-inch tub drains. So you never have to take this funnels out, once you put it in your drain it stays in your drain and it funnels all the hair down.
