Fix a Toilet Not Flushing: Troubleshooting & Repair · Step 3 of 3
In this video
Allow the tank to fill completely without interference. Observe the final water level once the fill valve shuts off on its own. The water level should be about a half-inch to one inch below the top of the overflow tube. If the water level is too high and constantly spills into the overflow tube, the fill valve float needs to be adjusted lower. If the valve never shuts off at all, it needs to be replaced.

FAQs
What tools are absolutely necessary for this project, and are there any others that would be helpful?
You will minimally need pliers and a multi-bit screwdriver. It's also helpful to have a sponge or small bucket to remove excess water from the tank before replacing the flapper, and a utility knife can be useful for trimming the new flapper chain if it's too long.
What safety precautions should I take before starting this toilet repair?
Always turn off the water supply to the toilet using the shut-off valve behind or below the tank before beginning any work. This prevents accidental flooding. It's also advisable to wear gloves for hygiene and have old towels or rags on hand to manage any spills.
Is this project genuinely suitable for a beginner, and what's the typical cost?
Yes, this project is very beginner-friendly and primarily involves simple adjustments and part replacement. The total cost is generally low, usually less than $20, as a new flapper typically costs $5-$15 and basic tools like pliers and a screwdriver are common household items.
What should I do if my toilet still isn't flushing correctly after following all the steps?
First, re-check all adjustments: flapper seal, chain slack, and water level. If problems persist, inspect the flush handle mechanism for breakage or looseness, and ensure the fill valve is properly refilling the tank. Mineral buildup in the rim jets of the toilet bowl can also impede flushing and may need cleaning.
