The trap is there to keep the drain itself from clogging. The trap can get clogged though if it meets with certain objects, like a kid’s toy, giant wads of toilet paper, or paper towels. A plunger can take care of this problem; with the rubber covering the entire hole, push up and down on the handle.
Similarly, it is asked, how do I keep my toilet from clogging?
A slow or weak flush often indicates that a clog is forming in your toilet drain. Instead of waiting until no water at all will go down, take care of the problem immediately. Plunge slow or weak flushing toilets as they occur. Use a toilet plunger, which has a necklike end on it.
