The answer to 'how to fix toilet repair' is to first identify the specific issue with the toilet, such as a clogged or leaking toilet. For a clogged toilet, use a plunger to try to clear the blockage. If that doesn't work, you may need to use a plumber's snake or auger to clear the clog. For a leaking toilet, check the wax seal under the toilet and replace it if needed. You may also need to tighten the toilet bolts or replace the fill valve or flapper if the leak is coming from those components.
Fixing a toilet yourself can often be done with basic tools, but if you're not comfortable doing the repairs or the issue persists, it's best to call a professional plumber. They have the expertise and specialized tools to properly diagnose and fix toilet problems.
