A constantly running toilet every 20 minutes usually signals a faulty flapper or a worn-out fill valve. The flapper may not be sealing properly, causing water to leak into the bowl. To solve this, check the flapper for any wear and replace if necessary. If the flapper is fine, inspect the fill valve, which controls water flow into the tank. A simple adjustment or replacement of these parts can often fix the issue and save water.
