Washers are tiny rubber or silicone parts inside taps that help stop water flow completely when you close them. Cheap, poor-quality ones harden or crack quickly, leading to annoying drips. Drip-drip-drip not only wastes water, it also drives you slightly crazy at night.
Better-quality washers last longer, seal more effectively, and withstand pressure and temperature changes better. The price difference per piece is usually very small compared to the cost of calling a plumber repeatedly.
It’s like buying decent tyres for a car—small part, big impact on how smoothly things run.
