Second, the common sense of saving water is to take a shower and save water. Take a shower with a shower nozzle: (1) Learn to adjust the ratio of cold and hot water. (2) Don't leave the water in the sprinkler on all the time, let alone open it. (3) Get wet from head to toe as much as possible, then rub the whole body with soap and rinse it for the last time. Don't wash your hair, upper body, lower body and feet alone. (4) Take a bath with concentration, seize the time, don't be carefree, or wash while chatting. Don't have a big water fight with your good friends in the bathroom. Remember: time is water! (5) Don't take the opportunity of taking a bath to "wash clothes and shoes by the way". Take a bath in the bathtub, pay attention to: don't fill the water, 1/3-? ? Four pots are enough. Water Saving in Toilet (1) If you think the water tank in the toilet is too large, you can put a brick or a Coca Cola bottle filled with water vertically in the water tank to reduce the amount of water flushed each time. However, it should be noted that bricks or coke bottles should not interfere with the movement of water tank components. (2) The water tank always leaks the most, and the water stop rubber is not strict, and the water is not stopped. After the water is full, it flows away from the overflow hole; If the water stop rubber at the outlet is not tight, the water will keep flowing away, and the water inlet pipe will keep filling. (3) Using the collected household wastewater to flush the toilet can make multiple uses of one water and save clean water. (4) No matter the size or thickness of the garbage, it should be removed from the garbage passage, not flushed with water from the toilet. Tips for solving toilet leakage In the past, the bucket in my toilet often leaked. I thought of a simple and easy method, which has basically solved the water leakage problem after nearly a year. The main reason of water tank leakage is that the copper wire used to connect the handle with the leather cup is often stuck, so that the leather cup can't fall down, and the water leakage can't be completely blocked if the leather cup doesn't go down, which leads to water leakage. You can rub the plastic belt into a plastic string, put the plastic string through the iron ring on the leather cup, and connect both ends to the handle rocker arm. Plastic rope is strong and not afraid of blisters, and it is changed once every six months. Users with leaking water tanks may wish to have a try. How to save water in washing machine Washing clothes by washing machine is labor-saving and convenient, but it also has some shortcomings, that is, it uses three-fifths more water than washing clothes by hand. How to save water as much as possible? You might as well insist on washing more than three pieces of clothes with the washing machine, and the small one or two pieces by hand. Especially, you should insist on cleaning the foam before rinsing, so that the clothes will be clean after rinsing twice. As a result, more than one third of water can be saved. More than one water (1) You can wash your feet and then flush the toilet after using the face washing water. (2) A vat for collecting waste water should be prepared at home, which can completely guarantee the water needed for flushing toilets. (3) Rice washing water and boiled noodle water are used to wash dishes and chopsticks, which can remove oil and save water. (4) Water-watering flowers in fish farming can promote the growth of flowers and trees. Washing dishes saves water. When washing dishes at home, it is best to wipe off the oil on the tableware with paper first, then wash it with hot water, and finally rinse it with more warm or cold water. Toys are children's close companions. However, some toys (such as water guns) need to consume water, so they are not worth recommending, especially in places where water resources are scarce. There are also some naughty teenagers, splashing each other with water under the tap water, very happy, unconsciously, the clean ground is wet, passers-by are scared to hide, and a lot of water is wasted. How bad! In winter in the north, water pipes are easy to freeze and crack, causing serious water leakage, so special attention should be paid to prevention and inspection. For example, (1) Covered sand washed away by floods in rainy season should be filled before winter to prevent water pipes from being damaged by shallow freezing. (2) Anti-freezing equipment (anti-freezing bolts, anti-freezing wooden cases, etc.) should be installed on faucets and water pipes outside the house. (3) Where there is ice in the house, it should also be wrapped in sacks and wrapped with straw ropes. (4) The doors and windows of the house with water pipes should be pasted, and attention should be paid to the indoor heat preservation. (5) Once the water pipe is frozen, don't bake it with fire or scald it with boiling water (that will damage the water pipe and faucet due to sudden expansion). You should wrap the faucet with a hot towel to help thaw it. Household water records as the saying goes, diligent writing avoids thinking. If you record the readings of the water meter at home at a fixed time every day (at a fixed time in the morning or evening), there will be many benefits. (1) The daily, monthly and annual water consumption can be easily found out, so it is no longer blind to pay the water fee. (2) Because the water consumption has been recorded, we can see whether there is waste or not, and we also know where to start saving water. (3) It is not very difficult to write it down every day, but it will take months or years, which is a modest interference test for perseverance, perseverance, patience and carefulness. (4) Write down this journal, and you can see the change of water consumption. What is the relationship between this change and factors such as temperature, cloudy eyes, dryness and wetness? Does it have anything to do with changes in family living standards (buying electric fans, refrigerators, air conditioners, changes in eating habits, etc.)? Who says this is not scientific research? Flow is the amount of water flowing out (flowing through) per unit time (for example, 1 second). Measuring the flow of tap water at home is the same as measuring the flow of the Yangtze River, but the method is different. First prepare a regular bucket and calculate its volume (for example, 18.6 liters); Prepare another horse watch, or an ordinary watch. When measuring, firstly, open the faucet to the maximum extent, and when the water flow is balanced, move the bucket to full, stop the timing and read the duration (for example, 23.4 seconds); The measured flow value is the volume divided by time, that is, 18.6/23.4=.795 liters/second. For the sake of reliability, measure it three times and take the average of the three results. If a water meter is installed at home, you can know the water flow by reading the water meter, and it is more convenient to measure the flow. Small water-saving experiment When you think of adopting a water-saving method, you can do an experiment yourself, which must be very interesting. For example, put bricks in the toilet water tank, and you can know the change of primary water use by measuring the flow. From the household water consumption records, we can also see the change of water consumption in one day and one month, and we can roughly estimate the change. It is everyone's responsibility for water-saving propagandists to save water. Only when everyone pays attention to saving water can the water shortage leave us, life will be stable and harmonious, and the environment will be beautiful and comfortable. After we teenagers understand these truths, we should not only do it ourselves, but also do a good job in propaganda and tell our relatives and friends so that everyone can save water. This is also what we can do to contribute to society.
