10 Household Items That Could Destroy Your Drains
Omelettes

Omelettes are a favorite meal, but many people misunderstand how to dispose of eggshells. Some think that crushing eggshells will keep them from blocking pipes, but this can still cause plumbing issues.
When eggshells go down the drain, even small bits can stick together with moisture and other debris in the pipes. Over time, these fragments can gather and form a larger blockage. Eggshells can also mix with grease and food, making tough clogs that are hard to clear.
The rough surface of eggshells can wear down pipes, especially in older plumbing, leading to leaks and more problems. It is important to be careful with eggshell disposal to keep your plumbing in good shape.
