Fix a Toilet That Won't Flush: Troubleshooting Guide · Step 3 of 3
In this video
The most common cause of a running toilet is a faulty flapper or seal. Inspect the flapper for any signs of wear, warping, or mineral buildup. If it appears old or damaged, it should be replaced. Before installing a new flapper, it is crucial to clean the flush valve seat where the flapper rests. Use a soft cloth with white vinegar to wipe the seat clean of any deposits to ensure the new flapper can create a perfect seal. It's recommended to replace the flapper or seal every three to five years as a part of routine maintenance.

FAQs
How difficult is it to fix a toilet that won't flush, and how long does it usually take?
This is typically a beginner-level DIY repair, making it very accessible. Most issues, like adjusting the chain or water level, can be fixed in 10-20 minutes. Replacing a flapper might take slightly longer, around 30 minutes, especially for first-timers, but is still straightforward.
What essential tools do I need for this toilet repair, beyond the cutting pliers mentioned?
Besides the Angled Head Diagonal Cutting Pliers for chain adjustment or replacement, you'll primarily need a good pair of waterproof gloves for hygiene. A sponge or old towel can be useful for drying the tank if you replace the flapper, and a bucket might be handy to catch any remaining water.
Are there any important safety precautions I should take before starting this repair?
Always turn off the water supply valve behind the toilet before working inside the tank to prevent accidental overflows. Wear gloves to maintain hygiene, as toilet tanks can harbor bacteria. Avoid using harsh chemicals to clean inside the tank, as they can damage components.
I've adjusted the chain, and the water level is correct, but my toilet still flushes poorly or runs constantly. What else could be wrong?
If the chain and water level are correctly adjusted, the issue is likely with the flapper itself. Even if it doesn't look visibly damaged, an old, stiff, or ill-fitting flapper can cause leaks and poor flushing. Replace the flapper to ensure a tight seal and proper water release for optimal function.
