Millions of questions toilet recalled
According to a recent report by the US "New York Daily News", the Consumer Product Safety Commission of the country has received 304 complaints about toilet explosions since 2011. Among them, 14 consumers were injured, some people were injured by injuries, some injured their faces and Front chest. The problem toilets use the third generation of pressurized flushing system 503 produced by Sloan Flushmate. The toilet products produced by the well-known American toilet brands such as Kohler, American Standard, Gobo, and Ajia from 1997 to 2008 may have safety hazards caused by explosions and injuries due to the use of problematic accessories.
It is understood that the problem accessories are used more in the United States. Since June of this year, Flachmet has recalled millions of problem accessories in the United States. In Canada, approximately 9,000 toilets have been “impliedâ€.
The staff of the Flachmet Beijing office said that the Chinese market uses the company's fourth-generation 504 series. The technical specifications of the two series are different, and the fourth generation does not need to be recalled. In addition, the involved toilet brand companies also launched self-examination. American Standard and Kohler have issued a statement recently saying that the toilet products in the Chinese market did not use the batch of problem accessories.
There have been toilet bursts in my country.
According to Flachmet, the recalled toilet flushing system releases air pressure, which may cause the tank lid to be flushed or even the tank to burst. According to reports, the pressurized flushing system is a pneumatic flushing device that uses the raised water surface to compress the internal stored air when the water tank is filled with water. Pneumatic flushing is like a “pushing†force, which is higher than the traditional flushing device and saves water. However, if the pressure is released when the air pressure is released, the water tank will instantly become a powerful "bomb". The device is likely to break the water tank cover, and may also blow up the toilet and threaten personal safety. .
Xie Xin, secretary-general of the National Federation of Industry and Commerce Sanitary Committee, pointed out that since July last year, the bathroom special committee began to investigate the mainstream brand of toilet products in the industry, and has not found the above problems. The design concept of the domestic water-saving toilet is mainly to use the siphon principle to save water through the water pipe equipment, without the need for external pressurized equipment, generally no such bursting problem occurs.
There have been too many toilet bursts in our country, mainly because the physical strength of the toilet is not enough. The qualified toilet finished product should be fired at a high temperature of 1200 ° C for about 20 hours. Some inferior products have a short firing time and the surface looks very smooth, and in fact does not reach enough strength. Once the water pressure of the flushing toilet is large, it may burst.
In addition to the Vlasmet brand, there are also domestic companies that produce and sell pneumatic flushing devices, most of which are used in toilets for hotels and restaurants. Zhao Gang, director of the Plumbing Inspection Department of the National Building Materials Hardware Plumbing Testing Center, said that in 2011, China issued the national standard “Pressure Flushing Device for Sanitary Ware Toiletsâ€, which involved the relevant testing standards for pneumatic flushing devices. Therefore, after the products produced after this have passed the test, there is generally no bursting problem.
Users can self-check or overhaul
If you are still worried about the safety of your home toilet, you can check it yourself or ask a professional to overhaul it. Generally speaking, the toilet tank using the air pressure flushing device is a closed container, and the whole toilet is connected. When flushing, a pressure is formed from top to bottom to wash away the dirt, and then the inner wall will eject a Small shares of clear water.
Pick a product that is heavier and has a crisp sound. The high-quality toilet has high temperature during firing and has reached the requirement of full porcelain. The weight is heavy. The firing temperature of the middle and low-grade toilet is low, the firing time is short, and the weight is light. Tap the toilet. If the sound is hoarse and not crisp, the product is not cooked and there may be a safety hazard.
Shop for well-known brands and keep notes. When the toilet uses a pneumatic flushing device, it is necessary to use a sealed water tank. It is difficult for consumers to judge the quality of their own when purchasing, and keep the good bills for the future.
The glaze should be smooth, uniform and free of flaking. According to the national standards, the inner and outer pipes of the toilet should have ceramic sealing glaze to avoid the smell and smell. In particular, it is necessary to touch the inner corner. If the glaze is used very thin, uneven, and the hand feels rough, the toilet will have a higher chance of leaking in the future.
