How does the Fluidmaster fill valve “signal” water leaks?
When a tank leak lowers the water level, the Fill Valve’s float cup drops, triggering the Valve to refill the tank (even when the tank hasn’t been flushed). This on/off sound is an immediate indication of water waste. The cause is typically a faulty flapper. Rod-and-ball type units begin refilling after only the slightest water loss, a silent process than can go undetected, wasting water for months (or longer). Back to top. 18. Yikes! My toilet is about to overflow! Quickly reach into the tank and (A) lift the float up to stop the fill, or (B) push the tank stopper or flapper down onto the valve seat and hold while you turn off the water supply valve. Back to top.
