A toilet that runs every 15 minutes usually indicates a problem with the flapper or fill valve. First, check the flapper for wear and tear, ensuring it seals properly. If not, replace it. If the flapper is fine, inspect the fill valve for any debris or malfunction and clean or replace it as necessary. This should resolve most issues.
