The toilet is a sanitary ware that directly contacts the stained bacteria, so its daily sterilization and cleaning is a necessary process. The emergence of various types of toilets has made our cleaning time easier, but we need to pay attention to the use of toilets. Toilet cleaners are chemicals, which may have a good effect on toilet cleaning, but the backflow of the toilet may directly lead to pollution of household water sources, and home improvement becomes a source of pollution. It is not very pleasant!
"Please do not put blue toilet blocks in the water tank of your own toilet. The toilet block is only suitable for foreign buildings with double water supply system. There is almost no such water supply system in China. There is no one-way check valve for the main valve and the sub-valve. Under the effect of negative pressure, the polluted water will flow back into the tap water system, calling for an immediate stop of this behavior!"
Recently, this news spread rapidly on Weibo and friends. Brushing the toilet is very horrible, time-consuming and laborious, and has to endure the smell. Putting a toilet block has become a choice for many people. So, does a small toilet block really bring so much trouble?
Toilet, toilet cleaner, toilet block
Neighbors flow out blue tap water
In life, there are many cases where the toilet blue water flows back into the water pipe.
In July last year, in Wolong Xiaocheng on Lianqian West Road, Mr. Wang opened the faucet, and the outflow was actually light blue tap water, but there was no similar situation in other households in the community. After testing by the technical staff of the Municipal Water Group, the blue tap water system was caused by the influx of toilet cleaner used by the residents on the upper floor.
Restore the principle of "instillation"
Toilet water back into the home
How does the blue toilet block cause the tap water to turn blue? How does the water in the tank flow into the water pipe?
Let's look at a "blue water pollution experimental model." The whole model consists of these parts: left side: simulated flushing glass water tank, simulated urban water supply pipe network from the upper water pipe; right side: simulated residential garden water supply pipe network, simulation floor.
After the experiment began, the water quality monitor put a solid toilet cleaner into the toilet tank and opened the city water pipe network valve to fill the tank with water.
As the water level in the tank rises, the solid toilet detergent gradually melts, and the original transparent water turns blue. At this time, the inspection personnel interrupted the water supply of the urban pipe network, which is the “water stop†encountered by the residents on weekdays.
A strange scene happened: I saw the blue water in the left toilet tank began to flow backwards, slowly spread to the right residential courtyard water supply pipe network, and then into the water supply point of the residents of the right unit. When the faucets of the residents of each unit are turned on, the water flowing out turns blue.
Toilet block should be used with caution
In case of "blue water", it should be put clean and reused.
It is reported that the composition of the toilet block contains various inorganic acids and corrosion inhibitors, organic acids, thickeners, surfactants, etc., which will cause certain pollution to the water source.
"Now the toilet tank is not easy to hide dirt, as long as it is often brushed, please try not to use the toilet block to avoid water pollution when returning." Water staff reminded that if you must use the toilet block, be sure to A backflow prevention device is installed on the toilet tank.
According to reports, the amount of water generally returned will not be much, unscrew the tap water tap, put more water for a while, the water will become clear. If the tap water turns blue, open the tap to clean the blue water, then boil the water before eating.
Expert: It is said that the toilet block is not very carcinogenic.
The water soaked in the toilet block is really carcinogenic as the network uploads. In this regard, Fengcheng Chemical expert Feng Zhanjun said that it is not reliable to say that the toilet block is carcinogenic.
Feng Zhanjun said: "At present, most of the toilet blocks on the market contain dyes, spices and various inorganic acids. These chemical components will cause certain pollution to the water and cause certain irritation to human skin. Injury, but to say that it is carcinogenic, the basis is small. As long as the residents do not drink water containing the components of the toilet block for a long time, they will not have much impact on the body."
Feng Zhanjun specially reminded residents to use toilet blocks, and do not use them with chlorine-containing products (such as 84 disinfectant, bleach, etc.), otherwise it will produce highly toxic. In order to prevent the toilet water containing the toilet block from flowing back, the public can clean the toilet with safe and environmentally friendly white vinegar.
