To unclog a slow-draining toilet, first try a dish soap and hot water soak. If that fails, create a tight seal using a flange plunger, or clear deeper blockages manually with a toilet auger. For weak flushes, clear the rim jets and siphon jet of mineral buildup.
You can also try to clear your slow draining toilet using everyday household products. Popular methods include using liquid dish soap, laundry detergent, or a baking soda and vinegar solution to dislodge blockages.

What NOT to Do When Unclogging a Toilet
Plumbers typically use a specialized plumbing tool called a toilet auger (or closet auger) to break up or retrieve stubborn clogs. If the blockage is easily cleared, they rely on a heavy-duty flanged or bellows-style plunger to force the obstruction through the pipe.

To fix a slow-flushing toilet, first check the tank's water level and adjust the fill valve if it's too low. Next, inspect and clear clogged mineral deposits from the rim jets and siphon jet holes in the bowl, as these commonly restrict flushing pressure.
Use baking soda and vinegar - Pour 1 cup baking soda followed by 2 cups vinegar, let sit 30 minutes. Consider a toilet auger - For stubborn clogs, a toilet snake can break up the obstruction. Call a professional - If DIY methods fail or clogs keep returning.
