In a recent inspection report of the toilets announced by the General Administration of Quality Supervision, Inspection and Quarantine, some unqualified technical indicators of toilets make people wonder: what do the indicators of washing function, water seal depth, and installation relative position mean in the end? These "unfamiliar" nouns affect the performance of the toilet? When buying a toilet, what should you watch in addition to price, shape, and water saving? Experts pointed out that the purchase of toilets should be comprehensively considered.

â—† Do not blindly pursue water saving
Toilet water consumption is the conventional 3L, 6L and other values. It is understood that some companies claim that the water consumption can reach 1.5L, that is, use 1.5L of water to wash away the dirt. Hu Yunlin, a professor-level senior engineer at the National Center for Quality Supervision and Inspection of Building Materials, pointed out that merchants now use more water for toilets as a selling point to promote their products. They also give consumers the impression of “smaller is better,†but actually, this understanding is Incorrect.
Hu Yunlin said that the smaller the number of liters, the smaller the amount of flushing, and the less water used to flush dirt, but these are relative. Businesses now focus on "provincial water", but consumers need to consider the comprehensive function of the product - after the water, can not be washed clean. According to experts, there is still a horizontal distance between the toilet and the riser of the corridor. Although toilets with too few ascents can flush dirt out of the toilet, they may not be able to directly flush it into the riser, causing dirt. Blocked in the cross tube. Some old houses with relatively long horizontal pipes do not recommend the use of toilets with a small amount of water.
â—† Little difference in flushing methods
At present, the market is mainly based on the “flush-type†and “siphon-type†toilet flushing products. When the reporter visited the market, the salesman had different opinions on the two flushing methods. For example, "siphon-type" merchants advertise their own products with low noise, while the straight-down type advertises the province's water, and point to the siphonic toilet when the flushing needs to stay for a period of time or it will not be clean and inconvenient. What is the truth? How should consumers choose?
"No matter what kind of flushing method, the key is to look like it is not clean." Hu Yunlin said that the flush toilet does save some water, and the sound of flushing the siphon toilet is indeed slightly smaller, unless the consumer is saving water and There is a high demand for noise protection, otherwise it can be ignored. As for the problem of “siphoning needs to press the button for a period of time while flushing,†the expert stated that the toilets of both flushing methods require a continuous stay. Otherwise, the parts are not fully activated, and the height of the float bucket is not enough. Not easy to clean, it may also lead to water leakage accidents. Therefore, as long as the flush is clean, regardless of the flushing method, consumers can choose, there is no real difference between the two effects.
â—† Wash function is very important
Hu Yunlin said that "washing function" refers to "the ability to flush clean water at one time." If you can't clean it at one time, you have to flush it again and you'll be charged for water. Some toilets reduce the water consumption of the toilets in pursuit of water saving. If the washing function is not good, it will outweigh the benefits, and it is not really water saving.
â—† The water absorption rate is small
"Water absorption rate" refers to the material of the toilet bowl - the water absorption rate of the ceramic itself. The higher the water absorption, the easier it is to absorb dirt. Hu Yunlin believes that because there is a layer of glaze on the surface of toilets, the size of the water absorption itself is not of much reference value. The unqualified items in this project are inconsistent with the water absorption rate of the product itself and the marked water absorption rate.
â—† pay attention to the thickness of the pipe diameter
When choosing a toilet, also pay attention to the minimum diameter of the pipe. Experts said that if the business can provide the appropriate test, consumers can put a table tennis to see if they can go through. In general, if the pipe diameter is too small, it is easy to block. When consumers choose, they can also touch the pipe to see if they are smooth and whether the glazing is even.
â—†Do not forget to check the water level
The water tank is the place for water supply and water storage. The consumers can check when purchasing the toilet: The normal conditions of the toilet tank should have the following rules: During normal operation, the water level should be lower than the height of the overflow, and the height of the outlet should be higher than Overflow port height and marked with "CL" sign. The “CL†line, also known as the safety line, must not be raised above this line to prevent the water in the tank from returning to contaminate the water supply pipe when the water supply pipe is stopped and the pressure drops. This is also a “safe water level technical requirementâ€. Content. If there is this line, it means that the manufacturer at least noticed this.
â—† water seal relationship cleanliness
"Depth of water seal", "surface area of ​​water seal" and "rescue of toilet water seal" determine whether the toilet will be returned. Hu Yunlin pointed out that the national standards have clearly defined values ​​for "water seal depth" and "water seal surface area." Insufficient "water seal depth" can easily cause odors in the sewage pipeline to return to the room. Different manufacturers use different molds. According to the characteristics of their own furnaces, some ceramics may be deformed during the firing process. Therefore, there is a possibility that the water seal depth of products of the same brand and the same model will be different. It is possible that the same brand of the same model of different products failed this indicator. If the surface area of ​​the water seal is too small, it will lead to easy contamination. “Recovery of water seal†refers to the situation where the toilet water is flushed with new water. The new stream should be quickly covered and can be maintained at a certain height.
â—† bathroom installation pay attention to details
Whether it is toilets, bathtubs or washbasins, the installation quality also has a great influence on the use of the product in the later period, and some details have to be paid more attention.
Toilets: Some workers use mounting bolts to install toilet bowls. The toilets are fixed to the floor and the base is sealed with cement. Hu Yunlin believes that this method is not recommended. First, when the bolts are fixed, it is easy to cause the ceramics to break when too much force is applied. The bolts are too tight and can easily lead to cracking of the ceramics. In addition, the expansion and contraction rates of cement, ground, and ceramics are different, and there may be toilets. The condition of being swelled. He suggested that the toilet bowl can be fixed on the ground with sealant, which can not only play a fixed role but also play a sealing role.
Basin: Hu Yunlin pointed out that if it is under the basin, it is best to use brackets to hold it. Although there is also a high-strength sealant to fix the basin under the table, it may cause the glue to tear the bowl.
Bathtub: When installing the bathtub, first place the floor level and allow the bathtub to maintain a certain gradient so that the waste water can be discharged quickly instead of forming a puddle in the bathtub. Hu Yunlin pointed out that the bottom of the bathtub needs to be cushioned, otherwise there will be support support around the bathtub. If the bottom is empty, it will easily cause deformation of the bathtub and affect the service life. The sealing of the bathtub and surrounding walls with a sealant is also a non-negligible link to avoid odors. He also reminded that maintenance holes must be left and problems could be easily repaired.
