As a plumbing expert with years of experience in dealing with various household plumbing issues, I can tell you that a toilet running randomly can be a sign of several underlying problems. The most common issue, as you've mentioned, is related to the flapper, which is a crucial component of the toilet's flushing mechanism.
The flapper is a rubber or plastic piece that covers the flush valve opening in the toilet tank. When you flush the toilet, the flapper lifts, allowing water to flow from the tank into the bowl. After the flush, the flapper should close tightly to stop the flow of water. However, over time, the flapper can become brittle due to age or the quality of the material. This can lead to a poor seal, allowing water to seep continuously from the tank into the bowl. This is often referred to as a "running toilet," and it can waste a significant amount of water.
Another issue that can cause a toilet to run is sediment buildup on the flapper or in the flush valve. Minerals in the water can accumulate over time, forming a hard layer that interferes with the flapper's ability to close properly. This sediment can also cause the flapper to stick, preventing it from sealing off the valve completely.
Here are some steps you can take to diagnose and potentially fix the issue:
1. Inspect the Flapper: Check the condition of the flapper for signs of wear or damage. If it's cracked, brittle, or warped, it's likely the cause of the problem.
2. Check for Sediment: Look for any signs of mineral deposits around the flapper or in the flush valve. If you find any, you may need to clean the area.
3. Adjust the Fill Valve: Sometimes, the fill valve can be set too high, causing the water level in the tank to be too high. This can lead to water overflowing into the overflow tube and then into the bowl.
4. Replace the Flapper: If the flapper is damaged or if cleaning doesn't solve the issue, you may need to replace it. This is a relatively simple DIY project that can save you a lot of water and money in the long run.
5. Call a Professional: If you're not comfortable with plumbing or if the problem persists after trying these steps, it's best to call a professional plumber to diagnose and fix the issue.
Remember, a running toilet is not just a nuisance; it's also a waste of water and can lead to higher water bills. Addressing the issue promptly can save you both money and resources.

The most common issue with toilets randomly flushing is that the flapper has become brittle or sediment has formed on the flapper/tank which prevents the flapper making a complete seal. This will allow water to slowly drip from the tank into the bowl.Jun 22, 2015
