234 views

Toilets run intermittently usually because of a faulty flapper, which may not be sealing properly. Over time, flappers can warp or accumulate debris, causing leaks. To fix this, turn off the water supply, drain the tank, and inspect the flapper. If it's damaged or dirty, replace or clean it. Another cause could be the fill valve; if it's malfunctioning, consider adjusting or replacing it. Regular maintenance can prevent this issue and save water.
