A ceramic valve is a device that controls the flow of water in a toilet cistern. It is a more durable and reliable alternative to a rubber valve.
Ceramic valves are less likely to leak than rubber valves. They are also more resistant to corrosion and can withstand higher temperatures. This makes them ideal for use in hot water systems.
Ceramic valves are also quieter than rubber valves and have a longer lifespan. They require less maintenance than rubber valves and are less likely to need replacing.
