Toilet Fill Valve
Toilet Fill Valve

Your toilet is a precision-engineered appliance and is designed to work on a specific amount of water. The fill valve is the engine of this appliance; it drives flush performance and makes water saving possible by making sure that the right amount of water is used to flush the toilet.

No more - no less. As codes and legislation reduce the amount of water that can be consumed by a toilet, the fill valve becomes even more important. The new PerforMAX™ fill valve from Fluidmaster was designed to meet the needs of a changing market. It is the quietest and most powerful engine for your toilet that you can buy.
