A constantly flushing toilet is usually due to a worn-out flapper or a faulty fill valve. To fix this, check the flapper first: lift the toilet tank lid and see if it's sealing properly. If it's worn or not closing properly, replace it. If the flapper is fine, the issue may lie with the fill valve. Adjust or replace the fill valve to stop the constant flushing.
