Fix a Toilet Not Flushing: Troubleshooting & Repair · Step 2 of 3
In this video
Take the chain from the new flapper and attach its clip to one of the holes on the flush lever arm. Adjust the chain length so that there is very little slack. The chain should not be tight enough to lift the flapper, but it should be taut enough to open it immediately when the flush handle is pressed. Remove any extra chain links if necessary to prevent it from getting caught under the flapper.
Goal: Set the correct chain tension for proper flushing
- If the chain is too long (too much slack), the toilet may not flush completely. If it's too short (too tight), the flapper won't seal properly, and the toilet will continue to run.

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.
