A toilet flushing slowly or sluggishly is typically caused by insufficient water volume in the tank, a flapper that closes too quickly, or mineral scale buildup blocking the rim feed holes underneath the bowl rim. When calcium and lime deposits harden inside the tiny rim jet holes, they restrict the flow of water needed to wash the bowl and trigger the siphon jet, resulting in a lazy, weak flush that fails to clear waste effectively. Verification: Inspect and clean rim jet holes with a piece of wire and verify that the tank water level reaches the fill mark.
