If your toilet only flushes occasionally, it might be due to issues with the tank's components, such as a faulty flapper or a problematic fill valve. To address this, first, inspect the flapper for any signs of wear or improper sealing and replace it if necessary. Next, check the fill valve's adjustment and ensure it's refilling the tank properly. Sometimes, a partial blockage in the toilet's trap or drain line can also lead to flushing issues, so consider using a plunger or a plumber's snake to clear any potential clogs.
