Why is my toilet bubbling and not flushing properly?

Your toilet may be bubbling and not flushing properly due to a clog in the drain pipe, a malfunctioning flapper or fill valve, or a problem with the vent stack. It is recommended to check for any obstructions in the drain pipe, inspect the flapper and fill valve for any damage, and ensure the vent stack is clear of debris. If the issue persists, it may be necessary to seek professional Plumbing assistance.
