The tank, which sits up behind the bowl, contains reserve water for refilling the bowl plus the devices for flushing clean water into the bowl and refilling the tank. One of these devices—called a ballcock—is connected to the water supply and controls delivery of water to the tank.
The drop in water level is sensed by a float, ball, or pressure gauge, and this triggers the ballcock to refill the tank. When a conventional toilet is flushed, water from the tank rushes into the bowl through an orifice called the flush valve. Before you trip the lever, this valve is plugged with a rubber stopper, called a tank ball, flush valve seat ball, or the newer, more effective flapper or flapper ball.
When it receives a signal from the sensor, it opens or closes the water flow. The positive or negative signals from the sensor control the solenoid valve. The polarity of the signal determines if the solenoid will either engage a pull or push action. The valves control the water flow by using a rubber-like disc. When there is no signal, the valve is closed, meaning no water flow through the valve. The presence of body movement will send a positive signal to the solenoid causing it to pull the valve open for water to flow.
As a key spare part, the power source is also very important to supply the electronic parts with power. Battery replacement is easy, just open the battery box cover and put the new alkaline batteries into the box.
AC adapter, one side with a power plug and one side with waterproof connector connect with the sensor or control box, there is a power transformer inside the adapter. The input can be vv and output 6V-9V. The ac adapter is not expensive and can buy it separately. The diagramm is controlled by microchip and allows little power. Both the sensor and valve works with low power energy. Notice: please take care of the battery polarity. This is what you press to get the water flowing towards the bowl.
It is usually connected directly to the tank, and it activates a mechanism that lets the water flow down. You will also find the inlet valve. This is the part that controls the water that goes into the tank. When the tank is full, this inlet stops letting water in your skirted toilet. Then, you find the water-level ball. It is a plastic ball or a similar component that detects the ideal water level. When the tank is filled, it stops water from going in. Using the ball system, the toilet detects when it should keep the inlet open and let water drop into the tank.
The tank then stops filling when the floating ball detects enough water in the cistern. So it automatically lowers down to close the inlet valve or activates the closing mechanism to prevent the water from overflowing. So, how does a urinal flush valve work? The flush valve opens, letting water go into the bowl, covering the whole surface from side to side, and disposing of the waste by sending it into the drain.
But not all the water coming from the tank or plumbing system will go into the drain. At the same time, this S-trap provides a siphon action that makes sure every single piece of waste goes directly into the drain with no comeback. So, how a canister flush valve works exactly? What small processes go into the flush for it to work so perfectly? The water passes through small tubes or flushing holes in the rim to inundate it. Most of these holes are located on the rear part of the rim. When the water arrives at the bowl, then it starts inundating until it reaches a level where the siphon action starts.
