If there are more than a thousand different toilets referenced by manufacturers, the mechanics of a toilet vary little from one model to another. To find out what to expect without calling a plumber, simply lift the top cover and take a look inside the tank where most of the items to be adjusted or repaired are located to optimize toilet operation. The system is quite simple: the water rinses the cuvette when the release lever, actuated by the handle, is activated, which raises the lever and allows the water to flow into the tank. The valve, like the release lever, is lowered automatically by closing the tank tightly with the valve, while the float plays the role of a switch for the tap to which it is connected: as long as the water is not Not sufficiently raised in the tank, it continues to flow via the float valve. Once filled, the water brings the float up to the previously defined level closing the tap at the same time: the tank is full, the toilet is ready to be operated again.
This may sound very complicated but it really isn’t. If you are still unsure then don’t hesitate to hire a professional like your local Cary NC plumbers to come out and take care of it.
