Add a piece of wire to the water tank of the toilet to control the valve in the tank to be closed at any time. The flushing volume is only 1/5 of the original flush. This is a small secret for toilets discovered by Master Zheng of Beijing. According to a report from the Beijing entertainment newspaper, Zheng’s toilet tank and toilet are separate. Nowadays, there is a wire made of “elastic device†in the water tank. The wire is tightly wrapped around the overflow pipe of the tank first, and then the two ends of the wire are placed on the valve of the tank. When the water is flushed, the valve lifts the wire and releases the wrench of the water tank. Then, the elastic force of the wire springs the valve back to the closed state. "When flushing, just give the skin valve a little force and the valve will close." Master Zheng explained the water-saving principle of the toilet.
After measurement, after using the water-saving device, the amount of water used to flush the urine can be controlled at about 1/5 of the total volume of the water tank, which is 2 liters of water. According to a family of three rushing 10 urinates a day, if you use a 10-liter old toilet, you need 100 liters of water a day, and you need 3 tons of water a month; if you use Master's water-saving device, only use 20 liters of water a day. Only 0.6 tons of water was used for one month, saving 2.4 tons. And the cost of such a water-saving device is less than a dime.
