Overview
Flapper valve
When a toilet's handle is turned, a discharge mechanism is activated by means of a rod or chain. The mechanism may be a flapper valve, which is designed to sink more slowly than the water, which will exit to the toilet bowl below, so that the tank may empty. As the tank water level drops, the float descends and actuates the fill valve. Water is fed to the tank to replenish its supply, and a smaller flow is directed into the overflow tube to refill the bowl. Once the flapper valve closes, th…
Siphon valve
Another discharge mechanism, common in the United Kingdom, is a siphon (or syphon). The rod or chain lifts a piston that pulls an initial charge of water up into the siphon. When the column of water passes over the siphon bend and starts to fall down the exit pipe, the siphon action continues to empty the tank until the water in the tank falls below the siphon intake.
Ballcock valve
Toward the end of the discharge process, the ballcock responds to the drop in water level and refills the tank. Should the float or valve fail and allow the water level to exceed the fill line, the water will pour into the overflow tube and out to the bowl (in the flapper valve type) or to an outside drain (in the siphon type). Although this does not stop the wastage of water, it avoids the flooding that would otherwise occur after a single-point valve failure. Typically the fill valve is se…
