Why are installation diagrams important for toilet repair parts?

Toilet repair parts often include multiple components. Without a clear installation diagram, users may install parts in the wrong direction, miss small components, follow the wrong installation sequence, or fail to create a proper seal. A clear diagram helps show the position and order of each part, making replacement easier for end users. It can also reduce after-sales questions and return risks. For wholesalers and e-commerce sellers, clear installation diagrams are also important materials for improving the customer experience.
