How to choose a toilet tank inlet valve?

The inlet valve is a crucial component of the toilet. It comes in three types: all copper, copper-plastic, and all plastic, with the latter being most commonly used in households. Poor-quality inlet valves may lead to issues such as tank overflow, continuous water flow, or inability to flush despite the tank being full. Repairing such problems is difficult and may not provide a permanent solution, resulting in inconvenience. Therefore, it is advisable to purchase high-quality inlet valves from specialized stores.
