Starting in July this year, the new national standards for the sanitary ware and sanitary industry began to be implemented. The new standard clearly stipulates the average water consumption of water-saving toilets: the average water consumption of urinals does not exceed 3 liters, and the average water consumption for toilets does not exceed 6 liters. The average water consumption for a squatting pan does not exceed 8 liters. Products that do not meet these mandatory standards will not be allowed to be sold.
Sanitary new national standard implementation of the first month of water-saving toilet has become "a big waste of water"
When the new national standard is implemented for one month, what is the situation on the market? When reporters conducted inspections at home stores, the amount of water used for water-saving toilets (ie, "toilet traps") displayed on the market could basically meet the requirement of less than 6 liters. There was even 3.5% of water consumption on the market. Lith around the super water-saving toilet. However, at the same time, the reporter also discovered that the water-saving toilets are heavily trapped in the market, and some toilets that are known as water-saving toilets are actually large users of wasted water.
Water-saving toilet is popular
When the reporters visited the site, they found that toilets with a displacement of 6 liters or more had already been withdrawn from the market. Toilets with 6 liters and 6 liters or less had become mainstream in the market. The water consumption of these toilets is generally between 3.45 liters and 6 liters, and for some two-flush toilets, the water consumption for low-grade flushes is about 3 liters. Meet the requirements of the new national standard.
This kind of water-saving product is currently very popular in the market. Because water saving in summer has become a problem faced by many cities, relevant data surveys show that bathroom water accounts for about 60% to 70% of household water, among which flush toilets become large water users and account for three of domestic water consumption. More than one point, reducing the amount of toilet flushing is essential for saving daily water consumption. Coupled with the rumors that water prices are rising, the water-saving toilet on the market is very popular with the market.
Feeling tired but in it
However, it is such a water-saving toilet with less than 6 liters of water, but it may become a big waste of water! The reason is simple. Some toilet flushes use less water each time, but one flush is not clean and needs to be washed two or three times repeatedly. Water saving naturally becomes a waste of water.
Li Haiyun, the person in charge of the Dongpeng Sanitary Ware Business Department, told reporters that the selection of the toilet cannot be seen only in its nominal water consumption. If a small amount of the toilet is not flushed cleanly, then the wasted water is still more, so the comprehensive flush rate should be comprehensive. And indicators such as water exchange rate to measure the effectiveness of toilet flushing indicators.
What are the factors that affect the final water use in the toilet? Li Haiyun told reporters that the water configuration, toilet pipe design and ceramic glaze are all relatively technical, and it is easier to show product differences.
â€œAfter the same 4 liters of water, if some water parts take 2 seconds to allow the water to flow out completely, and some water parts will take 0.7 seconds to make the water flush out, it is of course 0.7 seconds for the water to make Faster water flow and better scour capacity, while larger diameter drain valves can achieve rapid draining, many toilet flush valves on the market are only 2 inches in diameter, and this series of products are 3 inches in diameter and 4 in diameter respectively. Inches, it is equivalent to its instantaneous water capacity of 2.25 times and 4 times the 2-inch product." Li Haiyun tells the reporter with Dongpeng Oscar toilets as an example.
The second factor is the toilet's pipeline. "Everyone knows that the thicker the pipeline is, the better it is. Therefore, the drainage diameter of 48mm or more is certainly better than the conventional 42mm. However, in the cramped space below the toilet, it is necessary to keep the pipeline smooth. Keep enough water seal height to avoid odor spills, and the technical content is not small."
The third factor is the glazed ceramics. Some of the products of small brands are not glazing in the interior of the toilet, and some of them are not glazing, but they do not choose a good glaze or the process does not pass, so the toilet is not easy to clean. . In addition to affecting the effect of flushing, if the toilet glazed surface is not smooth, it is easy to stink and odor, resulting in mold, affecting the service life of the toilet and negatively affecting the user's health.
