When your toilet fills up with water and then slowly drains, it's usually a sign of a partial clog in the toilet or further down in the drain line. The best immediate solution is to use a plunger to try and dislodge any blockage. If that doesn't work, a toilet auger can reach deeper clogs that a plunger can't. Regularly cleaning your drains and avoiding flushing non-decomposable items can help prevent this issue in the future. If the problem persists, calling a professional plumber may be necessary.
