How a fluid master works?
When the tank lever handle has been pressed, it lifts the flapper/tank ball by a chain/wire. This opens the flush valve, releasing water through the jet hole and rim into the bowl, where gravity siphons the existing bowl water down the trap.
Once the flapper/tank ball drops back onto the flush valve seat and the tank begins to fill with fresh water supplied by the filln valve. As the water rises in the tank, the float cup/float ball rises with the incoming water until the preset refill level is reached.
Basically, works the same as your normal toilet does. It is just a name brand product. Do you have one?
