The answer to 'how to unclog toilet repair' is to first try a plunger to dislodge the clog. Firmly place the plunger over the toilet opening and plunge up and down vigorously for 10-15 seconds. This can often clear a minor clog. If that doesn't work, you can try a toilet auger or 'snake' to physically break up the blockage.
If the clog persists, you may need to disassemble the toilet to access and clear the drain pipe. This is more involved and may require calling a professional plumber, especially if you're not comfortable working with plumbing systems. Professionals have the right tools and expertise to safely and effectively clear a stubborn toilet clog.
