Step 5 · Check for a Partial Clog

If the previous steps have not solved the problem, there may be a partial clog deep in the toilet's trapway or further down the drain line. A simple test is to pour a bucket of water (about 1-2 gallons) directly and quickly into the bowl. If this produces a strong flush, the issue is likely with the flushing mechanism in the tank (steps 2-4). If the bucket of water also drains slowly or swirls weakly, a partial clog is the probable cause. To clear this, use a toilet auger, also known as a closet auger or closet snake. Carefully feed the cable into the drain hole, protecting the bowl with the auger's rubber sleeve. Crank the handle to extend the cable through the trap, then retract it to pull the obstruction back or break it up.
