A plunger can be a useful tool for very minor toilet clogs that can easily be dislodged, but if you have a serious clog inside your toilet drain, a plunger most likely will not be very effective. If you have a toilet that is backing up regularly, you will need the assistance of a plumber who has the tools and equipment needed to remove a stubborn toilet clog. Toilet back ups are typically caused by flushing things down the toilet that do not belong, such as paper towels, “flushable” wipes, and feminine hygiene products, just to name a few things.
