Toilet repair
A toilet that runs needs a new flapper or fill valve. One that rocks or leaks at the base needs a new wax ring and possibly a flange repair. A toilet that clogs every week may have a partial blockage in the drain line or a low-flow design that can't keep up.

About toilet repair
A running toilet can waste far more water than most people expect, enough to show on a monthly bill. A leak at the base is worse: it soaks the subfloor quietly, and in a second-floor bathroom it eventually shows up in the ceiling below.
Toilet repairs are usually quick. The plumber's job is to tell a simple part swap from a damaged flange, a cracked tank or a drain problem.
